Problem 2 (chapter 18.3, 2 points): The lead-acid battery is commonly used in cars. One electrode is a lead grid filled with spongy lead Pb(s). The other electrode is a lead grid filled with spongy lead oxide PbO2(s). The net reaction that occurs is: Pb(s)+PbO (s+2H(aq) 2HSO (aq) ->2PbSO4(s2H 0(0) a) Write down the half reactions that occur at each electrode. b) Identify the oxidation state of Pb in each of the species: Pb(s), PbO2(s) and PbSO4(s). Explain. c) Identify...

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...
