(H2O2), a colourless liquid usually produced as aqueous solutions of various strengths, used principally for bleaching cotton and other textiles and wood pulp, in the manufacture of other chemicals, as a rocket propellant, and for cosmetic and medicinal purposes. Solutions containing more than about 8 percent hydrogen peroxide are corrosive to the skin. First recognized as a chemical compound in 1818, hydrogen peroxide is the simplest member of the class of s. Of the several processes of manufacture, the principal ones involve reactions of oxygen from the air with certain organic compounds, especially anthraquinone or isopropyl alcohol. Major commercial grades are aqueous solutions containing 35, 50, 70, or 90 percent hydrogen peroxide and small amounts of stabilizers (often tin salts and phosphates) to suppress decomposition. Hydrogen peroxide decomposes into water and oxygen upon heating or in the presence of numerous substances, particularly salts of such metals as iron, copper, manganese, nickel, or chromium. It combines with many compounds to form crystalline solids useful as mild oxidizing agents; the best-known of these is sodium perborate (NaBO2H2O23H2O or NaBO34H2O). With certain organic compounds, hydrogen peroxide reacts to form hydroperoxides or peroxides, several of which are used to initiate polymerization reactions. In most of its reactions, hydrogen peroxide oxidizes other substances, although it is itself oxidized by a few compounds, such as potassium perm...
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%. This was one of my highest yields yet. I felt that this was a good yield because part of this experiment is an equilibrium reaction. Hypochlorite must be used in excess to push the reaction to the right. Also, there were better ways to do this experiment where higher yields could have been produced. For example PCC could have been used. However, because of its toxic properties, its use is restricted. The purpose of this experiment was to determine which of the 3 compounds was formed from the starting material. The third compound was the oxidation of both alcohols. This could not have been my product because of the results of my IR. I had a broad large absorption is the range of 3200 to 3500 wavenumbers. This indicates the presence of an alcohol. If my compound had been fully oxidized then there would be no such alcohol present. Also, because of my IR, I know that my compound was one of the other 2 compounds because of the strong sharp absorption at 1705 wavenumbers. This indicates the presence of a carbonyl. Also, my 2,4-DNP test was positive. Therefore I had to prove which of the two compounds my final product was. The first was the oxidation of the primary alcohol, forming an aldehyde and a secondary alcohol. This could not have been my product because the Tollen’s test. My test was negative indicating no such aldehyde. Also, the textbook states that aldehydes show 2 characteristic absorption’s in the range of 2720-2820 wavenumbers. No such absorption’s were present in my sample. Therefore my final product was the oxidation of the secondary alcohol. My final product had a primary alcohol and a secondary ketone
Unfortunately, Maria is constantly aware of the children missing from her life and is border-lining depression. Didion shows readers many symptoms of Maria’s depression throughout the novel. For example, the narrator says “When she got home she thought about calling him [Les Goodwin], but instead she went upstairs and lay face down on Kate’s empty bed, cradled Kate’s blanket, clutched Kate’s baby pillow to her stomach and fought off a wave of the dread” (Didion 23). It is obvious that Maria is depressed; however, she cannot confide in anyone. She cannot confide in Carter because he is emotionally distant nor can she confide in her lover Les Goodwin because he is a married man. Thus, leading to Maria becoming self-destructive and unintentionally seeking an identity. For example after a party, Maria “was stopped for speeding outside Tonopah and when the highway patrolman saw the silver dress and the bare feet and the Ferrari registered to someone else” the officer found out it was indeed stolen ( Didion 154). Didion creatively shows readers that Maria is acting out unintentionally because of her lack of control over life. In fact, someone who was in his or her right mind would have not stolen a car from a famous person like the one Maria did. The people in Maria’s life Maria’s notices there is a problem and start to worry about her well-being. This is shown when
Maria Full of Grace is a film that depicts the struggles the protagonist, seventeen year old Maria, goes through as she becomes part of the drug trade in order for a better lifestyle for herself, her family and her unborn baby. The film begins in urban Colombia where the audience is introduced to Maria’s hopeless lifestyle, as she is the only provider for a house full of women and in a relationship with an incompetent young boy. As the film takes plight to New York City, Maria becomes a mule for the drug cartel, while pregnant, Maria is faced with many circumstances that threaten her life. Although Maria Full of Grace depicts a male dominated culture, many events portray Maria’s willingness to stand up against culturally defined
She had an abortion. Her daughter is taken away from her. She divorced carter. Her mother was killed or committed suicide on the road. She participated in BZ’s suicide but not helping him. Her career is on the verge of collapse if not already collapsed. She is in the mental health hospital. Maria has lost everything. As Tyler Durden, from the movie Fight Club says: “It 's only after we 've lost everything that we 're free to do anything (Fight Club CITE). Maria is in a position to reclaim her life because she does not owe anything to anybody anymore. A great example of hitting bottom and coming back is a success story of J.K Rowling, the author of Harry Potter Series. She recalls "An exceptionally short-lived marriage had imploded, and I was jobless, a lone parent, and as poor as it is possible to be in modern Britain, without being homeless ... By every usual standard, I was the biggest failure I knew" (Gillett). Yet she carried on and kept writing Harry Potter and chasing her dream and she ended up as the most successful writer of the modern era. She was laser-focused on her goals. That is a great example for Maria to follow. “Aside from being a good mother, her (J.K Rowling) goal was to get Harry Potter published. That’s it” (Roberston). Maria’s two goals could be rebuilding her life and getting Kate
Some of the areas that Maria would like to address are marital concerns (the romance, hanging out with people other than her husband’s coworkers, communication, spend more time doing outdoor activities), concerns regarding pleasing her parents even during adulthood (the guilt she feels about her parents making sacrifices to send her to the United States to obtain her college degree), and the pressure of her religious background (being Catholic and feeling that she could not divorce her husband, even if she wanted).
The plotting to assassinate Caesar took nearly the majority of the play. During Julius Caesar’s parade following his victory against Pompey: Cassius took Brutus off to the side and talked to him about his plot to kill Caesar, but Brutus does not understand why he should be killed. So Cassius says, “ I was born as free as Caesar; so were you”(1.2.96). Cassius is trying to use evidence that Caesar is mortal, so he can convince Brutus to join the conspiracy. Cassius finds Casca in the forest at night and begins a speech to get him to join as well. Cassius says, “you are dull, Casca, and these sparks of life that should be in a Roman you do want”(1.3.56) to Casca. Cassius comes to Casca also to convince him to kill Caesar with him. Cassius spends lots of time going around trying to get people in his conspiracy, and once he gets people they go on and plan how/where they will kill Caesar.
As stated by Aristotle, “a man cannot become a hero until he can see the root of his own downfall;” his hamartia must bring about his peripeteia and he must have a fate that is greater than deserved. However, if there were more than one contender for this pitiable position, who would be the real tragic hero? In Antigone by Socrates, though Antigone and Creon both show traits which could depict them as a “tragic hero,” Creon wins the role by far. Despite sharing the same fatal flaw of arrogance and pride, Creon’s tribulations and actions as he goes through a series of unfortunate events more closely fit the definition of a tragic hero than Antigone’s.
In the book Tragedy Of Julius Caesar by William Shakespeare, Cassius and his conspirators did not want Caesar to gain all the power. Cassius believed that Caesar was becoming too powerful so he came up with a plan to assassinate Caesar Cassius planted forged letters Cassius even told Brutus that Mark antony offered Caesar the crown.

Hydrogen peroxide is a liquid which contains hydrogen atoms as well as two oxygen atoms. The oxygen atoms are very strong oxidizing agents therefore in order to break this substrate down it must undergo oxidation. This can be done
The first experiments investigate the order of reaction with respect to the reactants; hydrogen peroxide, potassium iodide and sulphuric acid by varying the concentrations and plotting them against 1/time. An initial rate technique is used in this experiment so ‘the rate of reaction is inversely proportional to time.’ To find the order of reaction in respect to the reactants, 1/time is plotted against the concentration of Hydrogen Peroxide using the equation:
Hydrogen peroxide is an organic molecule only containing hydrogen and oxygen. The common name for hydrogen peroxide is hydrogen peroxide. The IUPAC ID name is dihydrogen dioxide. This molecule is pale blue but colorless in its purest form. Hydrogen peroxide occurs in nature very rarely. Hydrogen peroxide can occur in multiple states, such as, liquid, and gas. This compound is also odorless and can have a slightly acidic taste. The acidity of this compound ranges from a pH of 4.3-5.1 meaning this compound is a weak acid. The molecular and empirical formula is the same, which is H2O2. This was proven by Petre Melinkishcili. The structural formula is HOOH. The functional group in this compound is a peroxo group which is an oxygen attached to another oxygen. Hydrogen peroxide is the simplest compound of peroxide anion. Yet hydrogen peroxide is much more stable than peroxide anion.
Brutus is considered an honorable, noble man in Rome and it is important to Cassius that he becomes part of the conspiracy. In Act 1, Cassius and Brutus agree that Caesar becoming king would be detrimental to Rome. Cassius starts off persuading Brutus by describing how weak Caesar is. He states, “he had a fever when he was Spain, and when the fit was on him, I did mark how he did shake; ‘tis true, this god did shake” (I.ii.119-121). Cassius is trying to show Brutus that Caesar is not perfect or better than everyone else. In fact, he is weak and infirm. Next, Cassius makes the point that Caesar is too powerful and if he becomes king, he will rule over the people “like a Colossus” (I.ii.136). Brutus says he will consider joining the conspiracy if it is
Hydrogen sulfide is a colorless gas with an obnoxious rotten egg odour. H2S is highly flammable, noxious and vitriolic in nature. Many petroleum and natural gas processing industries produces H2S as a by-product gaseous stream. Most H2S in the air comes from natural sulfur cycle. Exposure to H2S can lead to various health issues like burning/tearing of eyes, cough, and shortness of breath. Moderate concentration can lead to respiratory issues. So it is advisable to make use of this gas in other industrial operations.
