In the reaction, CuO(s)+H2(g)⇒Cu(s)+H20(l). Pick out the following:
1) the substance which is oxidised
2) the substance which is reduced
3) the oxidizing agent
4) the reducing agent

Answer 1

1-H2O
2-CuO
3-CuO
4-H2
remember the substance which is an oxidising agent itself gets reduced and vice versa
