my chemistry lab did the composition of hydrogen peroxide. i am having trouble trying to fugure out how to fill in the table. i dont understand why “s” is added to pvnrt and how to apply that to my equation. these are the steps on how to solve but i believe they are rather confusing. please help! thank you! i dont know how to convert PV=nRT so m/s for the initial rate. im confused on how to fill out the...
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...
