Answer 2

Explanation:

The type of reaction which uses oygen and hydrogen are Oxidation and Reduction.

•Oxidation is the addition of oxygen to a substance

2Cu + O2 = 2CuO (copper id oxidized)

•Reduction is the removal of oxygen from a substance

Zn + CuO = ZnO + Cu (CuO is reduced)

•Oxidation is the removal of hydrogen from a substance

CH4 + 2O2 = CO2 + 2H2O (carbon is oxidized)

•Reduction is the addition of hydrogen to a substance

CO + H2 = CH3OH (CO is reduced)
