Synthesis of benzilic acid from benzoin utilizing a multi-step reaction. Names: Arian Karim TA Name: Sayantan Das Lab Day & Time: Thursday 7:30-11:40 Lab Section #: Abstract The main purpose of this experiment was to synthesize benzilic acid from benzoin. This requires a multistep synthesis with benzyl as an intermediate product. The first step required HNO3 as an oxidizing agent and the second step required KOH and HCl. The percentage yields of benzil and benzilic acid were 59.5%

Experiment 1: Synthesis of Copper Compounds Introduction This experiment involves the synthesis of compounds originating from pure solid copper. By applying solubility rules and the reactive properties of substances‚ many compounds which would otherwise be costly to extract from nature are able to be synthesized in the laboratory. Laboratory synthesized may sometimes be more economical than natural extraction‚ however it poses its own problems with the amount of substance that is actually yielded

Discussion Questions for Chapter Four of The Great Gatsby Where are the people when the Church bells are ringing on Sunday morning? What might this tell you about their morality? (65) They are still at Gatsby’s party. Fitzgerald does this to tell us their spiritual or community values are not nearly as important to them as having a good time and partying. What is the next piece of gossip we hear about Gatsby’s possible career? (65) He is a bootlegger. According to one of the young ladies

Minimum Wage For years there has been disagreement over whether the minimum wage should be raised or not. Some believe that by raising the minimum wage‚ many Americans would be able to rise above the poverty line and have access to their dream. Others disagree saying that raising the minimum wage would only make it more difficult for businesses to pay workers and people would lose incentive to work hard. The only just choice is to raise the minimum wage so that hard working Americans can exceed

GDF15/MIC-1 is a product of macrophage activation‚ suggesting that it may be involved in chronic inflammatory processes (-). GDF15 is a stress-responsive member of the TGF-β superfamily and initially described as macrophage inhibitory cytokine (-). Although GDF15 has been described in many solid tumors for almost 10 years‚ the nature of its receptor is still unknown. There is some evidence of Smad signaling pathway activation‚ suggesting GDF15 may act through TGF-β receptor superfamily pathways (-)

EXTRACTION Organic Chemistry Laboratory This experiment was conducted in order to compare single and multiple extraction of caffeine from dried tea leaves and to calculate the percentage yield of caffeine for both extraction procedures. The group was assigned to do the multiple extraction. Before the extraction proper‚ the water bath containing the anhydrous sodium carbonate and distilled water was heated. As the sodium carbonate dissolves‚ tea leaves were added in the mixture and allowed to

Loggerheads also modify habitats as a result of their foraging activities. The fragments of hard-shelled organisms that loggerheads consume are either discarded or ingested and later deposited with feces at a different location. By reducing the particle size of the shells‚ loggerhead turtles contribute to nutrient recycling in benthic ecosystems by increasing the rate of shell disintegration. Additionally‚ a foraging behavior called infaunal mining has a significant effect on substrate characteristics
