1. (2 point each, 10 points total) Balance the following reactions: a. C3H8+O2CO2+H2O b. Al+HClAlCl3+H2 c. KClO3KClO4+KCl d. Al2(SO4)3+Ca(OH)2Al(OH)3+CaSO4 e. CO2+H2OC6H12O6+O2 2. (8 points, 2 points per section) Let's consider the well-known combustion of Benzoic Acid, C7H6O2. Since this is earth, we assume that we have an excess of oxygen. C3H6O2+O2CO2+H2O a. Balance this reaction (2 points). Hint: the coefficient on the H2O is 6 . b. A student combusted her entire sample of benzoic acid and obtained 308.1 grams of CO2. (Assume 100% yield). How many moles of CO2 is that? c. How many moles of benzoic acid did she have? d. How many grams of benzoic acid did she have? 3. ( 6 points, 2 points per section) Chemical reactions rarely deliver 100% yield. Let's consider the reaction of iron III sulfate with excess potassium hydroxide. Fe2(SO4)3+KOHK2SO4+Fe(OH)3
