$CH_4 + 2O_2 \to CO_2 + 2H_2O$

• A. Total mass of methane and oxygen in reactants = total mass of carbon dioxide and water.
• B. Total mass of reactants = Total mass of products; therefore, law of multiple proportions is followed.
• C. Amount of $CO_2$ can be increased by taking any one of the reactants (methane or oxygen) in excess.
• D. Amount of $CO_2$ produced will decrease if the amount of any one of the reactants (methane or oxygen) is taken in excess.
