Wastewater having 22 mg/l dissolved phosphorous (po43−) is treated chemicaly with ferric sulfate ((fe2(so4)3) (concentrated solution of 165 gr/l as fe). how much stock solution (volume in ml) of ferric sulfate is needed per a liter of water treated to achieve 100% po43− removal? how much solids (on a dry basis) are generated in the process per a million gallons of water treated? (show your calculations and provide answers in ml (for volume) and kg (for solids))

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
