The teacher repeated the experiment with a different sample of the oxide of copper.
The teacher found that the oxide of copper produced 2.54 g of copper and
0.72 g of water.
Two possible equations for the reaction are:
Equation 1: Cu2O + H2 → 2 Cu + H2O
Equation 2: CuO + H2 → Cu + H2O
Determine which is the correct equation for the reaction in the teacher's experiment.
Relative atomic masses (Ar):
H = 1
O = 16
Cu = 63.5
