Gas and their Stoichiometry

All of the gas laws you have learned so far can be applied to calculate the stoichiometry of reactions involving gases as reactants or products. The coefficients in a balanced equation not only represent molar amounts, but also relative volumes. To solve gas stoichiometry problems, you will need a periodic table and a calculator. You will also need to write and balance the chemical equations for each problem. Select the best answer from the choices.
