Analytical Chemistry
A 1.0 M potassium chromate (KCrO4) solution is subjected to an incident radiation. It has been observed that the radiation was almost fully absorbed. Explain why would this happen and what is the incident radiation. (5pts)
Explain and describe what is most likely to happen if the concentration of the solution in number 7 is decreased. It quantitatively describes how the amount of attenuation depends on the concentration of the absorbing molecules and the pathlength over which absorption occurs. (5pts)

General Biology BIO121 Yeast Fermentation Lab Introduction Organisms stay alive by the utilization of energy through metabolism. The energy acquiring pathways in photosynthesis convert radiant energy from the sun into the chemical bond energy of carbohydrates. This photosynthetic process is limited to the producers or autotrophs, which include plants, photosynthetic bacteria and some protists....

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...
