An important reagent in organic chemistry is thionyl chloride, SOCl2. One synthetic route would be to react SO2 with HCl in the gas phase to produce SOCl2 and water. What is the entropy change for this reaction? (J/K•mole SOCl2)? (S˚ = 309.7(SOCl2), 248.2(SO2), 186.9(HCl), 188.8(H2O) in J/K•mole)

Phosphorus pentachloride, PCl5, an important reagent in organic chemistry for converting alcohols to alkyl chlorides (ROH ---> RCl), is hydrolyzed in water to form phosphoric acid and hydrogen chloride. In the gaseous state, however, PCl5 can decompose at 250oC according to the following reaction PCl5(g) <---> PCl3(g) + Cl2(g), for which K = 0.0240 If a 2500.-L vessel containing 3250. kg of PCl3(g) with a constant chlorine pressure of 3.525 atm is allowed to reach equilibrium, how many kilograms of...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....

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...
