Catalysts are molecules that can speed up the rate of a reaction and are regenerated, this allows for effective catalysts to be used in very small quantities with respect to the substrate being transformed. This experiment uses copper acetate as a catalyst at about 12% loading with respect to benzoin.
Calculate the amount of copper acetate used to convert 1.130 g of benzoin to benzil, if the catalyst loading is

2. If two different compounds have the same Rr value, how might they be identified using paper chromatography? 3. Why is it important to keep the spots on the paper as small as possible? 4. If the solvent pool at the bottom of the beaker touched the spots on the 1.5cm line, what would happen to the spots? How would you address this error? 5. If you were teaching a student how to do paper chromatography, what three pieces of...
Question to answer from the lab: What aspect(s) of the approach taken is/are NOT especially green? What changes might be made to make the overall process greener? The Lab Experiment Summary Polyethylene glycols such as PEG-400 are currently of great interest to organic chemists, since their application as reaction solvents is very intriguing (1). PEG-400 is non-volatile and nonflammable in nature, and also possesses important properties such as recyclability, ease of work-up, thermal stability and economical cost. In addition, the...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
