1. (a) Write the reaction between alum and alkalinity. Show that 1 mg/L of alum reacts with 0.5 mg/L of alkalinity as CaCO3 and produces 0.26 mg/L of Al(OH)3 and 0.44 mg/L of CO2.
(b) Write the relevant equation and the mg/L relationship for Ferric Chloride.

8. Many marine organisms generate shells from calcium carbonate (CaCO3). A. (4 pts) Write out the balanced chemical equation that corresponds to dissociation of calcium carbonate. B. (5 pts) One of the many consequences of climate change is ocean acidification, which occurs because rising surface temperatures allow more CO2 to dissolve in the water, resulting in increased H3O* concentration in the ocean. Using a chemical reaction and a...

Problem 4: Ethylene oxide (C2Ha0), an intermediate in the production of plastics, is produced by the partial oxidation of ethylene (Reaction #1) C2H4+ O2 CH4O 25% 1. Reaction #2-the combustion of ethylene to form CO2 and H20-is an undesired side reaction: 2. C2H4+ O2 CO2 H20 (Note: This reaction is not balanced) Assume no other reactions occur-specifically that recycled ethylene oxide is not further oxidized. Pure oxygen (not air) is used in the...
