Problem 2. Compare the effect of methane production from wetlands on atmospheric carbon dioxide to the effect of carbon dioxide release from wetlands due to aerobic respiration, denitrification, and fermentation-sulfate reduction? State all assumptions!

Problem 3. What is the hardness of the following water expressed as CaCO3 in mg/L? Ca+2 = 92 mg/L and Mg+2 = 34 mg/L.
