Rates of reaction - concentration Essay Example for Free

Rates of reaction concentration Essay This experiment tests how differing concentrations affect the rate of a chemical reaction. It will be done using a simple experiment where one substance is constant and the other is varying. Apparatus For each experiment I will need the following; 150 cm3 2 Molar hydrochloric acid 140 cm3 water 250 cm3 sodium thiosulphate 1 conical flask 1 measuring cylinder 1 stop clock 5 pieces of paper 1 pen Preliminary Work; Prior to this investigation, I conducted a preliminary experiment to determine the strength of my method in terms of accuracy and precision. I decided to test how the temperature of an experiment affects the rate of reaction. Therefore, I got 50 cm3 sodium thiosulphate and 40cm3 hydrochloric acid diluted with 10cm3 water. After pouring the two mixtures into a conical flask I placed it onto a black cross on a piece of paper and timed the time it took for the precipitate of sulphur produced to make the solution seem so cloudy the cross disappeared. The same experiment was conducted at temperature of 10Â °C, 20Â °C, 30Â °C, 40Â °C and 50Â °C. The two substances that I have chosen for preliminary work will give me an accurate indication of the time taken for the reaction to occur in the actual investigation, as unlike with most experiments, the chemicals produce the precipitate of sulphur which turns the solution a milky yellow colour which is easy to see clearly. From my previous work, I can see that the range of temperatures was enough to give a clear summary of the investigation; therefore, I am transferring the range of temperature to use as amounts of hydrochloric acid as I feel it gives reliable results. Method After retrieving all the apparatus that is needed to successfully complete the experiment, I will begin with drawing a large cross onto the piece of paper. Then I will measure out five different quantities of both water and hydrochloric acid using a measuring cylinder in the following Display complete essay The above preview is unformatted text This student written piece of work is one of many that can be found in our GCSE Patterns of Behaviour section.

The Popular Poet William Cullen Bryant

The Popular Poet William Cullen Bryant William Cullen Bryant is one of the most popular poets of the nineteenth century. He has attended most of the public occasions with a kind of poetry that reached all levels of society. He is a poet whose consistencies have overcome his contradictions. Due to the poet hard efforts in the hardest period of his life he was able to publish more than thirty four poems. He used the best and most pure language. He also used a clear theme in his poetry. Even though his poetry may at sometimes appear complex, and controversial, the poet presented every piece of it in an interesting easily understood way. Bryants confidence was a major aspect that led him to his creativity. The poet accomplished his success in poetry through his heart and experience. To really understand any of Bryants poetry we need to use our sense of imagination, seek, select, and carefully examine every piece of it individually. His poetry should be real for its meaning, and beauty without those furtive glances. (Mclean 74 ). When discussing any of Bryants poetry in any school, we will notice his seriousness, morality, and simplicity in all of his poems. Two of the most popular poems of William Cullen Bryant are the Yellow Violet, and Thanatopsis. These two poems if compared will show the unique style and technique Bryant used throughout his poetry. There is a unique pattern of comparison between the poems that can be explained in several ways. Bryant has added a great amount of thought which gave his poem the Thanatopsis its complexity and depth. The poet himself admits that a work of this kind cant be repeated. As much as there are thoughts that constantly attempted to change the idea of the poem, they all failed due to the strengths in the phrases that are strictly aimed at one purpose and one direction. What makes the Thanatopsis style unique is that nature supports its beauty to the graves of humans. When you look closely at the poem, you will notice that the poem suggests death is lonely. The phrase The Two Graves, (Matthew 22) explains the important need and desirability of privacy in death. A piece of poetry like the Thanatopsis has a unique strong emotional power. In the Thanatopsis, Bryant is very sensitive and close to nature. He considered death to be a very important element of nature. What Bryant here realized and beautifully put in words has enlightened his viewers to the simple truth about life. Bryant in this poem is emphasizing that death is not a negative thing, but a comfort of fait. What I find interesting in this poem is that it comforts others on the death of your future. This poem simply offers a simple comforting view of death and comfort for the living. Another intersecting point in this poem is that humans live in nature although each part of them as individuals is gone. He is saying that dont be scared to be a part of nature because you are going to join others who already became a part of it long before you. In the Thanatopsis you will find comfort and inspiration; comfort in death and the reality of it; and inspiration to all his viewers to understand and appreciate the presence of nature. Another important point about the Thanatopsis is that its an easy transition piece between deism and romanticism. Its clear in this poem that Bryant depended heavily on the New England nature, and unstable environment which all give his poetry its rationality. The language and style in the poem gave it its simplicity and easiness. Its clear that the approach of this poem is the problem of death. The poet also makes it clear that not only there are many persons from the past to share the experience of death because death is the fate of men everywhere in the present and even future generations. The poet also says that humans dont accept the nature of death because they know that they are going to lose their dignity being under the ground. The nature clarifies for those men that the men before them are all of the kings, the wise, and the good. So no matter how much dignity you have, or beauty; all these nature forms lend this dignity and beauty to the grave. Its the intellectual content and strong clear language that gave the poem its strong meaning. He also emphasizes that you should live your life the way you want, and never get affected by others thoughts about how you should live. Too many times we are afraid to be different. For any human to live without regret, they have to live their lives to the fullest while they still can. Here he means to not be afraid to do anything that we always wanted to do. He is also saying that since we are going to become dirt again, no one has the right to tell us how to live our lives. The beautiful way that the poet describes death gives the living and the dying much comfort in the process. Bryant is also saying that no one will ever be alone; so its easier to let someone go in this case. Another beautiful aspect about Bryants poetry is that it provides comfort to all humans no matter what their religious beliefs are. Bryant also is saying that death is a living but in another way which is nature and how you become a part of it. One of the poets best works is the yellow violet. The yellow violet principles are moral sense, beauty, and truth, also taste. In this poem, the nature talks to the humans who she loves who are familiar with it. When those humans are satisfied, the nature speaks in a beautiful sound, with a big smile. The nature cheers its people up. The poet here is advising you that if you think of death and its scary images go outside and enjoy the blessings of nature. Bryant here is also telling his reader that after we die, we will not be able to see the sun or the ocean anymore because the earth will eventually take all humans in to their original form. The nature and its existence are beautiful. Its clear in this poem that humans the nature for their following generations. Its said that this poem is filled with pleasurable sadness. Its a way to worn a man from any pride. The yellow violet is best explained as a description of a man rambling through a sensory laden wood. The best way to really explain and clarify the poem is that to divide it into three different sections that would make it easier to understand. First the man goes into the wood, then sees the violet, and finally gets the simple beauty of the violet and then applies all that to him and all humanity. Bryant continues to braise the violet while comparing its down to earth soul and nature to other flowers. Bryant also uses a vital imagery language easily captures us. A certain narrow and overly simplistic view of human nature that excludes a more candid, introspective, ironic, and a self critical view of humanity. (24). another important aspect is that Bryant attempt to be someone better than he was, better than those people who walk through nature. The poem suggests that he better look do wn at the people beneath him because all humans are the same in the sense that they are going to become a part of the nature. When you read the poem for the first time, you will notice the beautiful use of imagination to color and erase the danger and discomfort of death. Bryant also explains that death is a great representation to the end of any humans individual status, and any other qualities that the human race created for themselves. In the yellow violet its also clear that Bryant was a good observer of nature. Bryant was a poet who was able to link the nature of life, and the nature of nature in a simple easy language. If you read his poetry and understand it, you will notice the explosion of beautiful deep meanings that are directly linked to reality. Bryant in his clever ways describes how humanity will always change, but nature will stay the same; and how humans are a major part of the nature. The poet also points out that its the poorest, less known, and invisible; people in your surroundings are the ones who cheer you up. They will never let you down. So those who become rich, and work very hard on doing so forget that at the end they are the same as those poor ones. The wonders of nature here always repeat themselves. Bryant in this poem makes very important points about life. He clearly demonstrates that while life styles and cultures change, and die away, nature will remain the same. In conclusion, for anyone to really understand the beauty and depth of Bryants work, they have to understand who he was and his origin as a human. If you hate the fact of death, you have no choice but to accept it. At one point if not know your life, you will understand the strength Bryant goes through when he wrote this piece of art.

Final Paper on Social Theory -- idelologies, communist, democratic

I guess you quite remember the thoughts you strongly developed when you were in college? I still believe that smart brains of yours even though they are old. I hear you recently gave a public speech at the Kwame Nkrumah Memorial Centre and Kobby Graham, your Social Theory Lecturer at Ashesi was your guest speaker. How is he then? Guess what? Kobby is a strong advocate of anarchism. He believes in a stateless society. I do not know what you`ve grown to believe but I’ve always known you to be a strong fan of Socialism when you were young. I remember you constantly told us we were living in a situation you termed slavery in freedom for you think capitalism was unfair to the middle class. I guess his talk hasn`t influence your thoughts on socialism. Never mind! I know you are not that pliant. Well, I would like to emphasize on the ideology I think can provide the needed equality you always wanted for I think I also relates to the principles of socialism social democrac y for I believe in cooperation and relative equality unlike conservatives, social and common ownership unlike liberals (Heywood, 2012). I hope you are aware socialism isn’t only an ideology? If you care to know, remember when you were in college, your mum constantly told you to move to your village for your own share of the village land. Aside, the government of Ghana implemented a policy four years ago called the Single Spine Salary Structure (SSSS) which seeks to bring equity in the mode of payment of government workers. This is basically the idea of socialism especially the social democrats. Apart from being an ideology, it`s also seen as an economic system which seeks to allocate resources through a centralized system of government where mos... ...im I will be more than happy to see his anarchism work on planet earth.

Faith in Fear and Trembling by Kierkegaard Essay -- Faith Literary Ana

Kierkegaard believes that true faith can only be attained through a double movement of giving up rationality or logic, while at the same time believing one can understand logically. In â€Å"Fear and Trembling† Kierkegaard relates true faith to the Knight of infinite resignation and the Knight of faith; in this paper, I will examine this claim and show why Kierkegaard’s analogy is an excellent metaphor for the double movement which is required in one’s quest to attain faith and why. Kierkegaard’s position on faith is represented with the Knight of infinite resignation and the Knight of faith. The Knight of faith is regarded as the one who believes in that which is absurd. For, he is the knight that is able to believe in the things that are paradoxical. The Knight of faith is aware of the contradiction that occurs and rationally understands it, but believes despite this. Kierkegaard gives a description of this after relating the knight to one in love with a princess he will never have the chance to be with. He describes the knight in this situation claiming, â€Å"I nevertheless believe that I shall get her, namely on the strength of the absurd, on the strength of the face that for God all things are possible† (75). Kierkegaard gives insight into this knight by stating that, â€Å"On this Knight of faith is just as clear: all that can save him is the absurd: and this he grasps by faith. Accordingly he admits the impossibility and at the same time a ccepts the absurd† (76). The other knight Kierkegaard refers to is the Knight of infinite resignation. This is the knight who works within reason and is able to recognize the contradiction or logical impossibility when faced with a situation; such as the situation where Abraham is commanded by God t... ...at Kierkegaard expresses his honest feelings by stating, â€Å"but I do not have faith; this courage I lack† (63). Kierkegaard makes a valid point by stating that a leap of faith requires a double movement. Believing something is not possible before believing it is possible. Faith is not just something that comes and goes for some people. Attaining faith requires a growth through certain stages, the first one being accepting that something cannot and will not be. The two knights that Kierkegaard describes is one the most excellent metaphors to describe the stages a person must go through to make a true leap of faith.

Tragedy Archetype- the Stranger

The Tragedy Archetype: The Rebirth Within Prim Lerthirunvibul Y10D (Blue) The seven archetypes is a theory in which there are seven ways of story-telling namely Quest, Voyage and Return, Rebirth, Comedy, Overcoming the Monster, Rags to Riches and Tragedy. The Tragedy archetype is one of the seven archetypes used in story-telling mentioned by Christopher Booker in The Seven Basic Plots. This archetype is known to expect a specific reaction from the readers often using grief, destruction and death.As the archetype manifests itself through time, there are many ways authors have interpreted the archetype through their stories. An element in the archetype that can be carefully observed is the notion of Rebirth where the main character eventually comprehends their misinterpretation of the world and their blunders which had caused their destruction, typically hubris. This suggests that there is a part of the Rebirth archetype in the Tragedy archetype. The question is, is tragedy a type of t he rebirth archetype?The absurdist novel entitled The Stranger (The Outsider), also known as L’Etranger by Albert Camus clearly portrays the rebirth in the story but is still engulfed by the tragedy concepts seen in many literature examples. â€Å"Once you’re up against it, the precise manner of your death has obviously small importance† (Camus, 71). The Stranger, written by Albert Camus is a tragedy book based on the story plot of a man named Meursault who is a psychologically and socially detached individual. He is also known to be amoral, not caring or knowing what is right or wrong and sees feelings in a physical sense.In one scene of the book, his mother had passed away and instead of grieving, he impassively looks at his mother’s grave and refuses the re-opening of the casket, which surprises many. He is also not responsive to human emotions such as desires and love. When the prospect of marriage was mentioned by his recent lover, Marie Cardona, he responds with â€Å"If she was keen on it, we’d get married. † (28, Camus. ) The Stranger can go under the tragedy archetype where it is classified by Booker as ‘the hero as a monster’ since Meursault himself is the cause of his own death.This happened since he stopped a friend, Raymond Sintes from shooting an Arab who was his â€Å"mistress’s† brother. And for no apparent reason, he came back and killed the Arab with a gun. A factor that may have affected his actions was probably because of the condition of the beach that was â€Å"pulsing with heat† (38, Camus). Although hubris is a common cause in the tragedy archetype, Meursault did not think of himself highly or more superior than others, but rather as an observer where reality is harsh for those who have no poignancy.He does not express himself much but with the reader as an observer as well, this creates the feeling of sadness for the main character even though he doesn’t experience much of it. As the titles of the book says, he is merely a victim tortured by the difference in perspectives, this small difference makes him unique, or even a threat to others. Not only did Meursault set up his own death, but the society in which he lived in contributed as well. The core of the consequences can be traced by Hamartia ( ), a Greek term meaning the fatal flaw of the hero which causes their death in the tragedy archetype story.In The Stranger, Meursault’s flaw can be seen as his lack of emotions and his frankness. Even though being emotionless does not affect his daily life or well-being, the environment of the situation created was greatly affected. An example is of how the people in court see him and how they also judge his beliefs, not for what he is, but what he says. When Meursault met a magistrate who tried to convert him, he called Meursault â€Å"Mr. Antichrist† (45, Camus) for being open and truthful about his beliefs, this then advoc ated his execution.Meursault sees things that other do not, which is one of the main causes of the resulting consequence. Humans often act on impulse, not by logic and the miscommunication between the other characters and Meursault creates conflict and sadly, the majority regularly wins in the tragedy archetype. The tragedy archetype is known to end with death, which is the norm for many stories, including The Stranger as well. Booker had also stated that the archetype sometimes involves the rebirth of the main character which usually comes before the tragic end of the main character.In comparison to Looking for Alaska, a modern novel written by John Green, The Stranger is more eye-opening since the concept of rebirth is directly experienced by the main character whilst the rebirth element in Looking for Alaska is not quite clear because the main character, Miles, continues on with his life as nearly the same person even though his friend, Alaska’s, death had a tremendous eff ect on other characters. With the longer lingering rebirth in The Stranger, Meursault finds comfort in the end where he becomes a ‘new person’ within himself, which proposes the idea of self-discovery.In his last moments, Meursault thoughts were â€Å"To feel it so like myself, indeed, so brotherly, made me realize that I’d been happy, and that I was happy still. † â€Å"For all to be accomplished, for me to feel less lonely, all that remained to hope was that on the day of my execution there should be a huge crowd of spectators and that they should greet me with howls of execration† (76, Booker). Even though the happiness was short, there was still a change in him as seen before the end of the book. In Booker’s analysis of the rebirth archetype, there are two types of rebirth which is physical and mental rebirth.An example of a physical rebirth could be found in the folktale of The Sleeping Beauty as she literally wakes up from her curse. A mental rebirth example could be found in Crash (2004), where a Farhad, a character realizes that his rage had clouded his judgment and he becomes calm and content, different from how he was from the start. The Stranger goes under the mental rebirth category since Meursault’s own conclusions resulted in the enrichment of his own mind as he begins to accept things in life.However, this does not necessarily mean that The Stranger can be directly ‘put under’ the Rebirth archetype. When referring to Booker’s analysis, it is stated that â€Å"we have only seen this return of light partially, ultimately insufficient to prevail against the forces of darkness which have been unleashed, and which eventually sweep the hero or heroine away† (Booker, 192). This means that in the tragedy archetype, ‘the light’ which is the rebirth of the character, can be seen only for a moment before it dissipates with the main character’s demise.This could b e compared to a candlelight where it flickers in the dark but does not last forever since it cannot maintain the flame and eventually, will be engulfed by darkness, which is, the sins or the consequences that slowly yet surely, catch up to the main character. All in all, even though The Stranger contains the Rebirth of a character who wakes up from an inner sleep or obliviousness, the tragedy archetype had proved itself to be more complicated and deeper with many fundamentals and forms that had manifested overtime.This then revealed the inner workings of the archetype including the profound meanings in the book. It is difficult to justify realistic and life-like story into separate categories as there are many factors, emotions and feelings brought in different events. But as they say, the end justifies the means in this particular book where Meursault dies a miserable and solitude death within the clutches of society. Again, regardless of the light’ in the story, The Strange r is a tragedy story weaved with the rebirth archetype’s features which implies that the tragedy archetype could also contain mixes but still maintain its structure throughout history whether it is in an old-world or modern literature. In short, the tragedy archetype is one of the most interesting and riveting of the seven archetypes that seem basic; but with careful observation and research can prove to be a very useful way of story-telling that can be remembered by readers despite of the era or time in which the archetype had laid itself upon.Bibliography (Citations) Innovateus. â€Å"What Is Hamartia in Greek Tragedy? †Ã‚  What Is Hamartia in Greek Tragedy?

Open-Book paper Essay

Alpha and beta decay are two types of naturally occurring radioactive decay. In alpha decay, an unstable nucleus emits an alpha particle (? ), a particle made up of two protons and two neutrons. For example:1 2 In beta decay, a neutron in the nucleus is converted into a proton and a beta particle (i ), an electron. Specifically, as protons and neutrons are both made of quarks, i -decay converts an up quark into a down quark; releasing a i -particle and an antineutrino (an antineutrino has no charge or mass, so does not affect the chemistry of i -decay). This occurs by the weak nuclear force. 3 For example:4 This table shows some of the differences between ? -decay and i -decay emissions:5 ?-decay i -decay Particle emitted helium nucleus electron Relative charge +2 -1 Relative mass 4 0. 00055 Range in air < 10cm < 10m Stopped by Paper Aluminium foil Deflection by electrical field Low High The fundamental difference between radioactive decay and nuclear fission is that, whereas radioactive decay is spontaneous, nuclear fission must be induced. In nuclear fission, when an unstable nucleus absorbs a neutron, it splits, emitting more neutrons and setting off a continuous chain reaction. This leads to products with nuclear masses around half those of the initial nuclei, whereas in radioactive decay, the initial and final nuclear masses are relatively close together. The other major difference is that fission releases considerably more energy than decay. This energy comes from mass lost in fission, according to the equation E = mc2, where E is energy, m is mass and c is the speed of light. Synthesis of Elements in Stars Stars produce their energy from nuclear fusion, in which nuclei join together to make larger nuclei. Hydrogen is used in normal-sized stars:(e+ represents a positively charged electron, and ? e is a neutrino). This process requires temperatures of around 13 million K and pressures of around 300 billion atmospheres. 6 When almost all of the hydrogen has fused, the helium nuclei can collide to make nuclei such as beryllium:7 This leads to the creation of further nuclei containing four nucleons: carbon, oxygen, neon and magnesium. Once all the helium has fused, further collisions take place between the created nuclei. This leads to the production of small amounts of hydrogen and helium, producing most of the first 18 elements, such as lithium:8. Lithium can also be produced by the collision of a Beryllium-7 nucleus and an electron. The nuclear process that takes place here is electron capture, in which an atom captures an electron, turning a proton into a neutron and releasing a neutrino. This happens by the weak interaction, like i -decay:9 Smaller amounts of lithium can also be produced in the fission of some nuclei by cosmic rays and in supernovae, when heavy stars become unstable and explode. 10 Producing Energy through Nuclear Fission and Fusion. In nuclear fission, an unstable nucleus absorbs a neutron, exciting the nucleus, causing it to oscillate and split into two smaller nuclei. This process releases more neutrons, causing more nuclei to split, and so on. This is shown in Fig. 211 with Uranium-235. The energy produced by nuclear fission, by E = mc2, is 3. 2Ãâ€"10-11 J per fission. 12 Uranium-235 is used to produce energy by fission – see Fig. 313. Controlling this reaction:   Uranium-238 is mixed with uranium-235. Uranium-238 nuclei absorb neutrons but do not react by fission, breaking the chain in the reaction. Graphite moderators placed in between the uranium rods reduce the kinetic energy of the neutrons produced so they can induce fission.   Boron-coated steel control rods absorb neutrons, and can be moved in and out of the reactor. If they are fully in, the reaction stops. Nuclear fusion takes place when, under certain conditions, two nuclei fuse together. For example, with deuterium and tritium:14 The energy produced comes from the mass lost – 3. 17Ãâ€"10-29 kg 15 16. By E = mc2, this gives out 2. 86Ãâ€"10-12 J per fusion. On earth, for this to happen the nuclei must be in ionised plasma at temperatures of 15Ãâ€"108 i C. The problem with this is that it must be kept away from the walls of the container to minimise heat loss. To do this, a tokamak is used. This uses magnetic currents to keep the plasma from touching the walls (see Fig. 417). The walls are made of graphite, which is not harmed by the temperature. Both fission and fusion have several advantages and disadvantages for use in producing electricity: Advantages Disadvantages Fission Uranium-235 produces 3. 7 million times the energy per unit mass as coal18   Uranium-235 will not run out on the same timescale as fossil fuels19. It produces no gases that directly cause global warming   Fission produces waste radioactive actinides, which are dangerous for thousands of years   Fission has led to disasters such as Chernobyl in 1986, which caused over 4000 deaths20 Fusion The fuel – hydrogen – is abundant   The radioactive waste products have half-lives hundreds of years less than those of fission   Fusion is safer than fission, as only small amounts of products are used   It produces no gases that directly cause global warming   The conditions required for fission are hard to produce. The process used to produce energy by fusion is not yet perfect – see below Challenges Facing the Development of Fusion Power Stations The major problem with fusion is generating and containing the conditions required for the reaction. As detailed above, a tokamak is used, this has some problems. The plasma still touches the bottom of the chamber, and where it does this; hydrogen reacts with the walls forming hydrocarbon radicals. These can form a film, which flakes away into the plasma, affecting performance21. Possible solutions include removing the film with lasers22 or using tungsten walls, which would not erode23. A probable source of a solution is the International Tokamak Experimental Researcher, currently being built in France. It will be used as a prototype to test the reaction on the necessary levels required. Fusion should be available to produce commercial power by 2040.
