Stearic acid (C18H 3,02) is a typical fatty acid, a molecule with a long hydrocarbon chain and an organic acid group (COOH) at the end. It is used to make cosmetics, oin tmen ts, soaps, and candles and is found in animal tissue as part of many saturated fats. In fact, when you eat meat, chan ces are that you are inges ting some fats that con tain stearic acíd. (i) Define standard enthalpy of combustion for stearic acid (s) and write a balanced equation for the reaction. marksi (ii) Using the following standard enthalpy of formation, calculate the standard change of combustion for stearic acid. AH (k]mol1) -1948 Compound CHO H0 CO2 -286 -393
