Barium chloride dihydrate has the formula BaCl2 · 2H2O. Assume there is another hydrate (BaCl2 · xH2O). If 20.73 g of this other hydrate gives 16.22 g of anhydrous BaSO4 upon treatment with sulfuric acid, calculate the value of x (x will be an integer).

    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...
