One step in the production of vanadium uses the reaction of V20, with an excess of aluminum at high temperature to give vanadium and Al2O3. In a test run, 38.4 kg of vanadium is obtained from 72.0 kg of V205. Calculate the percentage yield of vanadium. Hint: What is the theoretical yield of vanadium?

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...
