2.4 One method of removing phosphate from wastewater effluents is to pre- cipitate it with aluminum sulfate (alum). A plausible stoichiometry (but not exact because aluminum and phosphate can form many different chemical materials) is: 2 PO³ + Al₂(SO4)3 2 AIPO4 + 3 SO4²- If the concentration of phosphate (PO) is 30 mg/L, how many kg of alum must be purchased annually to treat 40 L/s of wastewater? How many kg/yr of solid precipitate will be formed (dry basis) if all of the phosphate is precipitated as AIPO₂?

5) King Krator the Merciless has called on Pogo, a humble goldsmith, to make a crown for theKing. He gives Pogo exactly 14 oz of pure gold to fashion the crown and tells him that if hecheats the King, he will pay with his life ! Pogo leaves with the gold; he and his apprenticesspend two weeks in making the crown; finally he returns to the court. When Pogo returns withthe crown, King Krator finds that the crown weighs 397.25 grams, and has a volume of20.58cm3. King Krator asks the court wizard for the density of gold, and Wizard tells the Kingthat gold has a density of 19.3 times that of an equal volume of spring rain. Krator demands aslate, makes a few calculations, then sternly lifts his head to stare at Pogo. Does Pogo's headroll ?

O CHEMICAL REACTIONS Melan Solving applied mass percent problems The human body can get energy by metabolizing proteins, carbohydrates or fatty aclds, depending on the circumstances. Roughly speaking, the energy It gets comes mostly from allowing all the carbon atoms in the food molecules to become oxidized to carbon dioxide (CO,) by reaction with oxygen from the atmosphere. Hence the energy content of food is roughly proportional to the carbon content. one of the simplest carbohydrates. Using the Idea Let's consider oleic acid (C,,H2 0,), a fatty acid from which fats are made, and maltotriose (C1,H,0,), above about energy content, calculate the ratio of the energy the body gets metabolizing each gram of oleic acid to the energy the body gets metabolizing each gram of maltotriose.
