Concept: Balancing Chemical Reactions

Problem: 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.Write a balanced equation for the combustion of stearic acid to gaseous products.

We will begin solving this problem by analyzing what information we have:

Step 1: Recognizing the reactants and products.

In a combustion reaction an organic compound made of carbon and hydrogen or carbon, hydrogen and oxygen are combusted with oxygen to form carbon dioxide and water as products. 

C18H36O2 (s) + O(g) → CO(g) + H2O (g)
