Stearic acid (C18H36O2) is a fatty acid, a molecule with a long hydrocarbon chain and an organic acid group (COOH) at the end. It is used to make cosmetics, ointments, soaps, and candles and is found in animal tissue as part of many saturated fats. In fact, when you eat meat, you are ingesting some fats containing stearic acid. Determine the Δ

Hrxn for this combustion given the following information:  Δ

Hf of stearic acid = -948 kJ/mol, Δ

Hf of CO2 = -394 kJ/mol, Δ

Hf of water = -242 kJ/mol.

Calculate the heat (q) released in kJ when 261.3 g of stearic acid reacts with 974.4 g of oxygen. Enter a positive number to 0 decimal place.
