It does nothing for the victims of crime‚ but perpetuates the idea of retribution‚ thus maintaining the endless cycle of violence in our culture. It is a cruel and useless substitute for the elimination of those conditions--poverty‚ unemployment‚ homelessness‚ desperation‚ racism‚ and greed--which are at the

Prelab 5B Macrocyclic Synthesis OBJECTIVE: The objective this week is to produce Tetraphenylporphyrin and its metal complex. This will be carried out by condensation of 4 equivalents of Benzaldehyde and pyyrole in the presence of propanoic acid. The product will undergo UV/Visible Spectrum tests to determine its lambda max. The lambda max will show us the relationship between a conjugated system and the visible spectrum. PROCEDURE: Step 1: preparation of meso-tetraphenylporphyrin (TPP)

Nikki Vietz Ms Bontekoe Honors English 11 3 October 2013 Synthesis Essay By changing the word “nigger” to “slave” defeats the purpose of the Adventures of Huckleberry Finn being a historical piece of literature. Such a change means ignoring the past and the word “nigger” is part of that past. “Nigger” is demeaning and insulting but is its replacement any less demeaning and insulting. Changing the word would not only destroy the message that Mark Twain was trying to convey‚ but also America’s history

EXP-10 CHEM 233L SYNTHESIS OF p-BROMOANILINE Introduction: In this experiment‚ p-bromoaniline was synthesized in three steps starting from aniline. Since the amino group of aniline is a strong activator of aromatic ring‚ direct bromination is impractical (equation 1). In order to make a desired product‚ amino group needed to be protected as the acetamide which also maintained ortho and para position but slowed down the rate of reaction (equation 2). Slow reaction rate would increase

Determination of Trace Amount of Copper and Zinc in an Aqueous Solution by Atomic Absorbance Spectroscopy Abstract: The purpose of this experiment is to analyze a sample containing copper and zinc in trace amounts‚ where standard addition method was used and the instrument used is the atomic absorbance spectroscopy. The amount of copper obtained was 0.569 ppm ± 0.015 and for zinc we obtained 0.42 ppm ± 0.0027. Introduction: This method implies the excitation of particles in the solution sample

Synthesis Paper Introduction Exercise can be very challenging to commit to. As a young adult my ideas and hopes were to always begin and maintain a routine that would help me to stay active and healthy. I regretfully report that I have not yet committed to this effort. In high school‚ I ran with the track team and was faithful the Reserve Officer Training Corps which helped me to stay in shape and remain fit with much effort. This was just a part of my life and I enjoyed it

Critical Synthesis Urban Sociology introduced students to five seminal texts from the field. While studying cities (and their surrounding areas)‚ and their political‚ economic‚ and social institutions‚ it is important to understand the key themes covered in these books: contested space (both for the arenas of land development and redevelopments as well as for various geopolitical interests); residential segregation; poverty; inequality (and the roles that government agencies play in exacerbating

Synthesis The Tell-Tale Heart‚ and The Cask of Amontillado “The Cask of Amontillado” and “The Tell-tale Heart”‚ has a setting in the mid 1800’s‚ where the narrator in each stories killed another character‚ hid their victims and leaving no evidence behind. But both of these stories don’t end the same‚ one of these stories‚ the murder gets away‚ and the other faces his consequences. In “The Cask of Amontillado”‚ Montresor tells the story of the day that he took his revenge on Fortunato‚ because
