Nuclear Power After Fukushima” by Lucas W. Davis in 2011‚ attempts to break down the question and provide detailed analysis on this issue with collected data and professional knowledge. In particular‚ Davis’s research focuses on the costs during nuclear power generation and its competitive advantages in long run. On a broader spectrum‚ the writer considers both benefits and risks nuclear power brings to human life‚ and finally comes to a conclusion. As Lucas W. Davis suggests‚ the continuously

In the Texas vs Cobb case a man named Raymond Levi Cobb was first arrested in 1994 and confessed to a home burglary. In this process he denied that he killed the woman and child in the home but later confessed to his father which his father then went to report this to the police. Even though Cobb later waived his Miranda rights and confessed he was still indicted and sentenced to death. Cobb argued to the Texas Court of Appeals that after his confession he was denied his right to counsel because

to predict whether the reagents would cause an SN1 mechanism‚ SN2 mechanism‚ or both. When predicting the outcome of SN1 and SN2 reactions‚ the nature of the carbon skeleton‚ nature of the solvent‚ and the nature of the leaving group are all taken into account. The experiment called for a two part reaction‚ sodium iodide in acetone (SN2) and silver nitrate in ethanol (SN1). A series of 8 test tubes were each filled with a different substrate to be tested by these two reagents. Approximately 4 drops

the rest retain the purplish color of KMnO4. On the other hand‚ the five compounds in Bromine test with light reacted positively. In Bromine test dark‚ Hexane and Unknown hydrocarbon 1 did not react because light (UV) is absent. Lastly‚ in Tollen’s reagent‚ only Acetylene reacted positively and all the other compounds gave a negative result since they are all hydrocarbons.

The Synthesis of Organic Aspirin ABSTRACT: The purpose of this experiment was to find out how a reaction undergoes for a globally known painkiller called aspirin‚ and to become familiar with achieving successful yields. Aspirin is synthesized from salicylic acid and acetic anhydride. Those two chemicals are mixed together along with sulfuric acid to form a crude solid. Filtration is used separate the impurities from the crude aspirin. To get purified aspirin‚ the precipitate was heated until all

team searched for the presence of starch‚ glucose‚ lipids‚ and proteins through the use of indicators: Sudan III‚ Lugol’s iodine‚ Benedict’s solution‚ and Biuret’s reagent. After testing the gelatin solution in the presence of the indicators‚ the results showed that Lugol’s reacted‚ turning orange-pink (oils) and the Biuret reagent (protein) reacted with the gelatin solution‚ turning lilac. Thus it was determined that the gelatin solution held both proteins as well as oils. Introduction: Lipids

Experiment 15 & 16: Preparation of 1-bromobutane‚ an SN2 reaction Preparation of 2-chloro-2-methylbutane‚ an SN1 reaction Introduction The purpose of this experiment is to synthesize 1-bromobutane from 1-butanol and sodium bromide. In order for this reaction to reach completion there are four major operations that need to be performed. The four major operations include refluxing‚ simple distillation‚ separation‚ and drying. To begin‚ in order for the compounds to react they will be dissolved
