Introduction For this Module, I chose to explain and elucidate the topic, “Oxidation-Reduction Reaction” also known as Red-Ox Reaction not just because it is required for us to elaborate the most complicated matter for us, but also for the reason that I wanted to improve my understanding and comprehension regarding this topic. I really had a difficult time especially during assessments because I wasn’t a hundred percent sure that my answers were correct—I even had questions left out unanswered. I
electrodes. These reactions can be shown using "Half - Equation". Below, I have shown them using the example of Lead Bromide. [IMAGE]The lead bromide is separated into molten lead and Bromide. PbBr(l) Pb(l) + Br²(g) When lead Bromide is melted, the ions are free to move towards the oppositely charged electrode, because Lead Bromide is an ionic substance. [IMAGE]When the positive lead ions move to the negative electrode, they gain electrons in a reduction reaction: Pb²+ + 2e- Pb
Mitochondrion make use of a process known as oxidation to make fat acids and pyruvate acid into (indirectly) ATP and Pi (inorganic phosphate). The process goes as follows: 1) Oxidation of pyruvate acid into acetyl coenzyme A. 2) Oxidation of fat acids into acetyl coenzyme A. 3) Oxidation of acetyl coenzymes from step one and two into CO2 and NADH2. 4) Oxidation of NADH2 by oxygen forming water. 5) Synthesis of ATP coupled to NADH2 oxidation by process of oxidative phosphorylation
Hydrolysis of Oxoanions Nonmetals in positive oxidation states do not exist in aqueous solution as cations but rather as hydroxides or oxides. These species often act as oxo acids which ionize to form oxoanions in solution. The general form of an oxoanion is MOxy-. Since these oxoanions are quite different in their properties, Z2/r ratios for nonmetal cations do not give accurate predictions of their chemical behavior. A different approach is needed to determine what these elements will do when they
lesson “Reduction-Oxidation Reaction” really challenged my comprehension and computation skills in many ways. The first one is the complexity of instructions that are needed to be followed in order to arrive at the corresponding answer for a particular reaction. I basically confused the oxidation and reduction half reaction wherein I don’t know what elements will be reduced and oxidized. One of the things that I’ve confused is that I’ve mistaken the monoatomic charges for the oxidation numbers, wherein
Oxidation of Cyclohexanol to Cyclohexanone The oxidation of cyclohexanol to cyclohexanone involves the removal of hydrogen from the OH group. After separation and purification, an Infrared Spectrum will be run to determine the composition of the recovered material. Infrared Spectroscopy is a very powerful technique used in the determination of molecular structure and the identification of unknown organic materials. The infrared spectrum yields direct information about the presence or absence
Definition-corrosion, rust, oxidation Corrosion is the atmospheric oxidation of metals. Rusting is essentially a process of oxidation in which iron combines with water and oxygen to form rust. Rust is the reddish-brown crust that forms on the surface of iron. Rust, a chemical compound, is a hydrated ferric oxide Fe2O3·nH2O, where n is usually 11/2. The chemical mechanism of rusting is not fully known, but is thought to involve oxidation of metallic iron to ferrous ion, (Fe++) and reaction of the ferrous ion
final weight percent yield 2,4-DNP Tollen's test pathway .42g 67% positive negative oxidation of secondary OH Good Things My experiment went well. I began my experiment with .64g of 2-ethyl-1,3-hexanediol. The molecular weight of this compound is 146.2g/mol. It is converted into 2-ethyl-1-hydroxyhexan-3-one. This compounds molecular weight is 144.2g/mol. This gives a theoretical yield of .63 grams. My actual yield was .42 grams. Therefore, my percent yield was 67%
scale which is practical. Make note as to which electrode is the anode and which is the cathode. 9. When the voltmeter reads a positive voltage, the electrode connected to the positive terminal is the cathode and is undergoing reduction. The oxidation is occurring at the electrode connected to the negative terminal, the anode. 10. Prepare half-cells in other wells of the 24-well plates. 11. First make a diagram of the order of the solutions in the wells so the different solutions will
carbon monoxide - Roasting in air Depending on the reactiveness of the metal, looking at the reactivity series, you can tell how each metal can be extracted. What is meant by oxidation and reduction in the context of metal extraction? You can use oxidation and reduction to describe chemical reactions that combine with oxygen or you can use it to describe the electron transfer. At this stage, you probably just need to concentrate on the
brown when cut and exposed to air. This can be partly attributed to the action of enzymes which are organic catalysts. They speed up chemical reactions without taking part in the reaction. Enzymes are sensitive to temperature and pH and have optimal levels of each variable at which they will function at the fastest rate. For the browning reaction of an apple to occur, three conditions are necessary; 1. The enzyme know as phenolase must be present 2. The target/substrate of the phenolase
proteins that speed up chemical reactions. In their globular structure, one or more polypeptide chains twist and fold, bringing together a small number of amino acids to form the active site, or the location on the enzyme where the substrate binds and the reaction takes place. Enzyme and substrate fail to bind if their shapes do not match exactly. This ensures that the enzyme does not participate in the wrong reaction. The enzyme itself is unaffected by the reaction. When the products have been released
Sometimes the best way to learn is through experience. I have not experienced the aging process. My knowledge of the aging process has only come from what I have observed from the older people in my life and things picked up from various media. However, I have never discussed with someone, who has gone through so much of life, the process of aging and how they have managed it. Mr. Blackman taught me plenty about how to live life as it advances. I also have not had much experience working in group
Dostoevsky’s Notes from Undergound - Reactions to an Overdeterministic Existence Some of the works cited are missing Dostoevsky presents his Notes from Undergound as the fragmented ramblings of an unnamed narrator. On the surface, the character’s narration appears disjointed and reaches no conclusive end ing until the author intercedes to end the book. However, a close examination of the underground man’s language reveals a progression in his collected ravings. After expressing dissatisfaction
Reactions to Patriarchal Oppression by Jane Eyre and Bertha Mason Missing Works Cited Jane Eyre and Bertha Mason are both oppressed by the British patriarchal system were men are the makers, interpreters, and enforcers of social and political rules. However, these two women differ greatly in the ways that they accept and cope with the reality of their place in society, and it is these differences that ultimately determine their fate. Jane Eyre follows the rules. Although she initially revolts
Reactions to Hooks’ Feminism is for Everybody I am not a feminist simply because I was raised in a feminist household. I am not a feminist because I am an independent, educated woman. I am not a feminist because I am a bitter female, nor because I am a “woman scorned.” I am not a feminist because I hate men, nor because I am a lesbian nor because I like to listen to the Indigo Girls. To the contrary I love men and I am not a lesbian. While I agree with hooks that “feminism is a movement to end
"We are a peculiar people," Elder Bruce R. McConkie once said (McConkie 25). The Church of Jesus Christ of Latter-day Saints is one of a few "odd" Christian religions. Many of its practices have created much persecution and political reaction, polygamy being one of these. It created much social and political persecution of the Mormons. Most of this persecution had come from anti-polygamist Christians. This is ironic because the anti-polygamists believed in the Bible, but not polygamy, one of its
Reactions to Oppression in Jamaica and South Africa "Bob Marley said How long shall they kill our prophets While we stand aside and look Little did he know that eventually The enemy will stand aside and look While we slash and kill our own brothers Knowing that already they are the victims of the situation" Lucky Dube, Victims Lucky Dube is a reggae artist from South Africa singing in a fight against oppression in his country. Like Jamaica, South Africa has been oppressed
Reactions to Industrialism in Frankenstein and The Communist Manifesto The radical changes of the nineteenth century were unlike any the world had seen before. A sense of these changes were felt by all in many aspects; not just politically, but in social and cultural means as well. When Mary Shelley's Frankenstein was published in 1831, it was clear that many general elements of the romantic era were well reflected. Similarly, Karl Marx and Frederick Engels' The Communist Manifesto appeared
An investigation of neutralization reactions Aim Question : What is the effect of changing the concentration of an alkali, on the volume of acid needed to neutralise it, when acid is added to it? The plan is to use two acids (Hydrochloric & Sulphuric) and one alkali (Sodium Hydroxide). The reason I need to use two acids is; because the question applies to all acids and alkalis and to just use one of each would not enable me to come to a general conclusion. If there had been more
