Combustion problems is an advanced topic that draws on several calculation skills from previous presentations. These include determining formula mass, percent composition, and empirical formulas from percent composition. This Powerpoint presentation develops the logic by using stoichiometry to determine the masses of carbon dioxide and water formed during the combustion of methane. Then the percent composition and masses of these waste products is used to show that the mole ratio of the carbon and hydrogen atoms in these waste products is indeed 1 to 4. Finally, a sample problem is given with a step by step solution.
