Stearic acid (C18H36O2) is a typical fatty acid, a mostly hydrophobic molecule that exists in solid form at room temperature. It is used to make cosmetics, ointments, soaps, candles, and is found in animal tissue as part of many saturated facts. Any person who eats meat is likely to ingest some fats containing stearic acid. (a) Write a balanced chemical equation for the complete combustion of stearic acid to gaseous products. (b) Calculate its heat of combustion, given its heat of formation (Hf = -948 kJ/mol) (c) Calculate the heat (q) in both kJ and kcal when 1.00 g of stearic acid is burned completely.
