Consider the reaction CH4 + 2O2 = CO2 + 2H2 If 8.01 grams of CH4 are burned in excess O2, 445 kilojoules of heat are evolved. Heats of formation: CH4 = -74.8 KJ/mol, O2 = 0, CO2 = -393.5 KJ/mol Atomic masses: C = 12.01 g/mol H = 1.01 g/mol. From these data, calculate the heat of formation of water.
