1. Moles of Reactant to Mass of Reactant: Identify the iodide ions and ozone in the balanced chemical equation. Use mole ratio, then convert to grams. A method used by the EPA for determining the ozone concentration in the air is to pass an air sample through a bubbler containing iodide ions. The iodide ions remove the ozone according to the following reaction: O3(g) + 2 I-(aq) + H2O(l) → O2(g) + I2(aq) + 2 OH-(aq) How many grams of ozone...

(Q#1) Hydroxyapatite has the formula Ca5(PO4)3(OH) and is the main mineral component of dental enamel and bone, and encourages bone growth when placed as bone graft. Hydroxyapatite is prepared from aqueous acid and dilute calcium hydroxide solution. If you mix 115 g of 80.2 % by mass phosphoric acid solution with 74.8 g of calcium hydroxide, what mass in g of hydroxypatite is formed assuming the reaction goes to completion? (Q#2) Seratonin is a chemical neurotransmitter in the brain and...

Methane gas is burned with 30 percent excess air. This fuel enters a steady- flow combustor at 0.8 atm and 25oC and is mixed with the air. The products of combustion leave this reactor at 0.8 atm and 1600 K. Determine the equilibrium composition of the products of combustion and the amount of heat released by this combustion in kJ/kmol methane. Use data from the tables CH 25°C CO2, H3O chamber NO. O2 N2 1600 K 30% excess air 25°C...

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...
