In this lab‚ I calculated the heat of combustion of paraffin (candle wax) by burning a candle and holding a calorimeter (a soda can) filled with 98.7 mL of water above the flame. The heat released by the candle was absorbed by the water in the can. It was important to place the metal chimney around the candle so that minimal amounts of heat would escape; having too much heat lost to the atmosphere would cause extra error in the calculations. The assumption made was that all heat released from the

It is so crucial because it allows for the understanding of how molecules interact in order to create new products. Generally speaking‚ multistep synthesis could be useful in a practical application such as pharmaceutical chemistry. Synthesizing aspirin is a common example of a multistep synthesis reaction. Aspirin is typically taken as a painkiller or as a reducing-agent for fevers. In order to synthesize this product‚ the reactants salicylic acid and acetic anhydride

Background Information: Spectrophotometry is a method that measures how much light is absorbed by using the electromagnetic spectrum. By seeing which colors are absorbed and which are reflected scientists can determine what a substance is without having to touch them. This is possible because each substance has a specific absorbance spectrum‚ meaning that the absorption spectrum of two different substances cannot be the same. Purpose/Hypothesis: 1. The purpose of the experiment was to determine

THE SYNTHESIS OF MONSTER INC. In Monsters Inc. At the beginning of the story‚ depicted a company belonging to the monsters that find and produce energy from the screams of children being made afraid by them. They’re harvesting energy to keep from becoming extinct by going back to when humans were most prominent. Monsters must have relied on anti-human instincts to believe that just touching a human would corrupt their world like it did in the past. So they scare humans to gather their energy until

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

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

However‚ backstreet abortions were done‚ often ending in permanent injury or death. The 1967 Abortion Act was introduced to provide a safe alternative to backstreet abortions (Abortion). In 1973‚ the Supreme Court handed down its Roe v. Wade and Doe v. Bolton decisions legalizing abortion in all 50 states during all nine months of pregnancy‚ for

It does nothing for the victims of crime‚ but perpetuates the idea of retribution‚ thus maintaining the endless cycle of violence in our culture.
