2. You have an empty 42-gal barrel and a 5-lb bag of dry alum, Al2(SO4)s and are interested in making a 0.05 M solution with these materials. (a) Calculate the number of gallons of 0.05 M solution you can make with the materials you have on hand. (b) Suppose you put all the alum in the barrel and filled it full. Calculate the molar concentration of the resulting solution.

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...
