The Scarlet Letter - Analysis Essays - English-language Films

The Scarlet Letter - Analysis Nathaniel Hawthorne's background influenced him to write the bold novel The Scarlet Letter. One important influence on the story is money. Hawthorne had never made much money as an author and the birth of his first daughter added to the financial burden ("Biographical Note" VII). He received a job at the Salem Custom House only to lose it three years later and be forced to write again to support his family (IX). Consequently, The Scarlet Letter was published a year later (IX). It was only intended to be a long short story, but the extra money a novel would bring in was needed ("Introduction" XVI). Hawthorne then wrote an introduction section titled "The Custom House" to extend the length of the book and The Scarlet Letter became a full novel (XVI). In addition to financial worries, another influence on the story is Hawthorne's rejection of his ancestors. His forefathers were strict Puritans, and John Hathorne, his great-great-grandfather, was a judge presiding during the S! alem witch trials ("Biographical Note" VII). Hawthorne did not condone their acts and actually spent a great deal of his life renouncing the Puritans in general (VII). Similarly, The Scarlet Letter was a literal "soapbox" for Hawthorne to convey to the world that the majority of Puritans were strict and unfeeling. For example, before Hester emerges from the prison she is being scorned by a group of women who feel that she deserves a larger punishment than she actually receives. Instead of only being made to stand on the scaffold and wear the scarlet letter on her chest, they suggest that she have it branded on her forehead or even be put to death (Hawthorne 51). Perhaps the most important influence on the story is the author's interest in the "dark side" ("Introduction" VIII). Unlike the transcendentalists of the era, Hawthorne "confronted reality, rather than evading it" (VII). Likewise, The Scarlet Letter deals with adultery, a subject that caused much scandal when it w! as first published (XV). The book revolves around sin and punishment, a far outcry from writers of the time, such as Emerson and Thoreau, who dwelt on optimistic themes (VII). This background, together with a believable plot, convincing characterization, and important literary devices enables Nathaniel Hawthorne in The Scarlet Letter to the develop the theme of the heart as a prison. The scaffold scenes are the most substantial situations in the story because they unify The Scarlet Letter in two influential ways. First of all, every scaffold scene reunites the main characters of the novel. In the first scene, everyone in the town is gathered in the market place because Hester is being questioned about the identity of the father of her child ( Hawthorne 52). In her arms is the product of her sin, Pearl, a three month old baby who is experiencing life outside the prison for the first time (53). Dimmesdale is standing beside the scaffold because he is Hester's pastor and it is his job to convince her to repent and reveal the father's name (65). A short time later, Chillingworth unexpectedly shows up within the crowd of people who are watching Hester after he is released from his two year captivity by the Indians (61). In the second scene, Dimmesdale is standing on top of the scaffold alone in the middle of the night (152). He sees Hester and Pearl walk through the market place on their way back from Governor Winthrop's bedside (157). When Dimmesdale recognizes them and tells them to join him, they walk up the steps to stand by his side (158). Chillingworth appears later standing beside the scaffold, staring at Dimmesdale, Hester, and Pearl. In the final scaffold scene, Dimmesdale walks to the steps of the scaffold in front of the whole town after his Election day sermon (263). He tells Hester and Pearl to join him yet again on the scaffold (264). Chillingworth then runs through the crowd and tries to stop Dimmesdale from reaching the top of the scaffold, the one place where he can't reach him (265). Another way in which the scenes are united is how each illustrates the immediate, delayed, and prolonged effects that

Balance Redox Reaction Example Problem

Balance Redox Reaction Example Problem When balancing redox reactions, the overall electronic charge must be balanced in addition to the usual molar ratios of the component reactants and products. This example problem illustrates how to use the half-reaction method to balance a redox reaction in a solution. Question Balance the following redox reaction in an acidic solution: Cu(s) HNO3(aq) → Cu2(aq) NO(g) Solution Step 1: Identify what is being oxidized and what is being reduced. To identify which atoms are being reduced or oxidized, assign oxidation states to each atom of the reaction. For review: Rules for Assigning Oxidation StatesAssigning Oxidation States Example ProblemOxidation and Reduction Reaction Example Problem Cu(s): Cu 0HNO3: H 1, N 5, O -6Cu2: Cu 2NO(g): N 2, O -2 Cu went from oxidation state 0 to 2, losing two electrons. Copper is oxidized by this reaction.N went from oxidation state 5 to 2, gaining three electrons. Nitrogen is reduced by this reaction. Step 2: Break the reaction into two half-reactions: oxidation and reduction. Oxidation: Cu → Cu2 Reduction: HNO3 → NO Step 3: Balance each half-reaction by both stoichiometry and electronic charge. This is accomplished by adding substances to the reaction. The only rule is that the only substances you can add must already be in the solution. These include water (H2O), H ions (in acidic solutions), OH- ions (in basic solutions) and electrons. Start with the oxidation half-reaction: The half-reaction is already balanced atomically. To balance electronically, two electrons must be added to the product side. Cu → Cu2 2 e- Now, balance the reduction reaction. This reaction requires more work. The first step is to balance all atoms except oxygen and hydrogen. HNO3 → NO There is only one nitrogen atom on both sides, so nitrogen is already balanced. The second step is to balance the oxygen atoms. This is done by adding water to the side that needs more oxygen. In this case, the reactant side has three oxygens and the product side has only one oxygen. Add two water molecules to the product side. HNO3 → NO 2 H2O The third step is to balance the hydrogen atoms. This is accomplished by adding H ions to the side that needs more hydrogen. The reactant side has one hydrogen atom while the product side has four. Add 3 H ions to the reactant side. HNO3 3 H → NO 2 H2O The equation is balanced atomically, but not electrically. The final step is to balance the charge by adding electrons to the more positive side of the reaction. One the reactant side, the overall charge is 3, while the product side is neutral. To counteract the 3 charge, add three electrons to the reactant side. HNO3 3 H 3 e- → NO 2 H2O Now the reduction half-equation is balanced. Step 4: Equalize the electron transfer. In redox reactions, the number of electrons gained must equal the number of electrons lost. To accomplish this, each reaction is multiplied by whole numbers to contain the same number of electrons. The oxidation half-reaction has two electrons while the reduction half-reaction has three electrons. The lowest common denominator between them is six electrons. Multiply the oxidation half-reaction by 3 and the reduction half-reaction by 2. 3 Cu → 3 Cu2 6 e-2 HNO3 6 H 6 e- → 2 NO 4 H2O Step 5: Recombine the half-reactions. This is accomplished by adding the two reactions together. Once they are added, cancel out anything that appears on both sides of the reaction.   Ã‚  Ã‚  3 Cu → 3 Cu2 6 e- 2 HNO3 6 H 6 e- → 2 NO 4 H2O 3 Cu 2 HNO3 6H 6 e- → 3 Cu2 2 NO 4 H2O 6 e- Both sides have six electrons that can be canceled. 3 Cu 2 HNO3 6 H → 3 Cu2 2 NO 4 H2O The complete redox reaction is now balanced. Answer 3 Cu 2 HNO3 6 H → 3 Cu2 2 NO 4 H2O To summarize: Identify the oxidation and reduction components of the reaction.Separate the reaction into the oxidation half-reaction and reduction half-reaction.Balance each half-reaction both atomically and electronically.Equalize the electron transfer between oxidation and reduction half-equations.Recombine the half-reactions to form the complete redox reaction.

In depth analysis about article Essay Example | Topics and Well Written Essays - 500 words - 1

In depth analysis about article - Essay Example The article contends that foreign trade does not necessarily increases the amount of value of commodity unless it is accompanied by increase in demand. This is important facet of economic principle that heavily relies on demand and supply of goods and services for optimal profit. The influx of capital and employability within the production process results in profits either due to new technology and methods that increase efficiency or there is decrease in wages that help to increase the percentage of profit. Thus, increase in revenue or decrease in consumption will result in accumulation of capital which can be gainfully employed for production of other commodities. They are indeed, vital inputs for trade and apply equally for domestic and foreign trade. Interestingly, the article also highlights that countries tend to favor import of those goods which have relatively higher cost of production. Ricardo gives example of corn which he says would be imported by England even if it has fe rtile land. Main reason is that it gains relatively higher profits on export of wine for which it has developed improved skill and technology which lower the cost of production.
