Question

When burning methane (methane + oxygen —> carbon dioxide + water, CH4+202–> CO2+2H2O), what would happen if you decreased the amount of oxygen?

A - more methane and oxygen will be produced

B - less methane and oxygen will be produced

C - more carbon dioxide and water will be produced

D - less carbon dioxide and water will be produced

Answer 1

Answer:

Less CO2 and H2O would be produced

Explanation:

Since you can only change the amount of reactants, you should be looking for compounds on the reactant side that contain oxygen. If you decrease something on the reactant side, compounds produced on the product side will be affected. Since both CO2 and H2O contain oxygen, and the O2 is the only reactant with oxygen in it, then the amount of CO2 and H2O will be reduced.
