Question

2CuO+H2→Cu+H2O balance a chemical equation

Answer 1

Answer:2 CuO + 2 H2 = Cu2 + 2 H2O

Explanation:

Answer 2

Answer:

1. 2CuO +2H2 = 2Cu + 2H2O

Explanation:

since copper is 2 in reactant side we will add 2 in product side before copper .... and in reactant side it is O2 so again we put 2 in front of H2O but now the hydrogen becomes H4 in the products side so we will put 2 in reactant side to balance the hydrogen .. Hence it is balanced ...
