Detailed Solution

In a given chemical equation, CuO undergoes reduction ( $Cu from +2 to 0$ ).

On the other hand the oxidation state of hydrogen changes from $0 to +1$ .

Therefore, the species CuO acts as oxidizing agent.

Note: In the electrochemical series reactivity order Cu is placed bottom of the hydrogen. Hence, H can displace Cu very easily.
