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.
