The institution of slavery was built on a corrupt foundation. William Craft explains in his novel that his intention is to create “a deeper abhorrence of the sinful and abominable practice of enslaving and brutifying out fellow-creatures” (24). Slavery as it is known now is a terrible practice that wrong millions of human beings‚ though that was not always the case. In the slave states‚ an entire race of powerless slaves was a social norm. Slaves were the backbone that built American society‚ and

The Cyclohexanol Cycle and Nylon Synthesis Samantha Stuckey CHE 233L Section 302 Department of Chemistry‚ DePaul University‚ 1110 W. Belden Avenue‚ Chicago‚ IL 60614 smstuckey@comcast.net May 8th‚ 2013 Abstract The first three labs of this organic chemistry experiment involved carrying out the first three parts of the Cyclohexanol Cycle. The cyclohexanol was first converted to cyclohexene and water by simple distillation (product: 6.5395g‚ 79.75% recovery). The cyclohexene then underwent a bromination

Synthesis of terpolymer PLGC: The terpolymer PLGC was synthesized using a reported procedure with a starting monomer ratio of 70:20:10 of L-LA‚ GL and Ɛ-CL respectively using the catalyst tin(II)2-ethyl hexanoate. The chemical reaction is given in the figure1. The yield % of the synthesized polymer was calculated by the equation: Yield %= (Weight of synthesized polymer)/(Weight of the monomers taken) ×100 Characterization of synthesized polymer: Chemical analysis using Fourier transform infrared

Unit 4 Assignment 4.3 Implementation of a Data Classification Policy Risk Assessment One the first steps in implementing an effective security plan is to periodically assess Organizational risks. Identifying and mitigating risk will help in establishing a security management structure and assigning security responsibilities. Without having an understanding of your risk you are unable to determine the proper security policies‚ procedures‚ guidelines‚ and standards to put in place to ensure adequate

Procedure 2.0 g of Mo(CO)6 and 10 mL of mesitylene were added into a 50-mL round bottom flask along with a small magnetic stir bar. A 30-cm reflux condenser was attached to the round bottom flask and a gas inlet was then connected to the condenser and to the bubbler. Since Mo(CO)6 and the product tends to react with oxygen at high temperatures this reaction must take place in an inert atmosphere. Therefore‚ the gas inlet was connected at the top of the condenser to a nitrogen source and was flushed

Thesis: According to psychologists and sleep experts‚ poor and insufficient sleep can have dramatically negative impacts on a students’ daily functioning particularly their school performances‚ which may include off-task behavior‚ drowsiness‚ irritability and students’ inability to focus so adolescents should be sleeping at least 8 hours a day in order to function at their mental best. Sleep Disordered Breathing And Daytime Sleepiness Are Associated With Poor Academic Performance In Teenagers. (NCBI)

Experiment 11: Synthesis of Dibenzalacetone by the Aldol condensation Introduction: The Aldol condensation reaction‚ under basic conditions‚ involves the nucleophilic addition of an enolate ion to another carbonyl group. The resulting product‚ a beta-hydroxy ketone or aldehyde‚ is called an aldol because it contains both and aldehyde group and the hydroxy group of alcohol. Condensations‚ including aldol condensation‚ combine two or more molecules‚ typically with a loss of a smaller molecule (including

Racism can be “defined as the hatred of one person by another or the belief that another person is less than human because of skin color‚ language‚ customs‚ place of birth or any factor that supposedly reveals the basic nature of that person. It has influenced wars‚ slavery‚ the formation of nations‚ and legal codes” (“What”). The face of racism over the past 50 years has changed but yet‚ some still stay the same. People made laws against racism and it is not as blunt anymore. But opinions and stereotypes

Preparation of Fruit Flavors (Pear) Abstract. In this experiment an assigned Ester is prepared‚ particularly n-Propanol. The Preparation was done via Fischer reaction. In this reaction‚ a reflux set-up is required. The reflux set-up was used in the liquid-liquid extraction. After adding an immiscible solution to the compound containing n-Propanol‚ the mixture now will have two layer: the Organic and Aqueous layer. The organic layer is the extract needed and its % yield is computed resulting to

Experiment # 3 Acetylsalicylic Acid Introduction: The purpose of this experiment is to create and isolate pure acetylsalicylic acid from the substances salicylic acid and acetic anhydride. Then one will find the melting point to determine purity. Procedure: Make a hot bath. Weigh some salicylic acid and place in conical vial. Add .480mL of acetic anhydride and a drop of concentrated phosphoric acid. Drop in a magnetic spin vane and attach air condenser to vial. Partially submerge it in
