Copper $(II)$ oxide

Vedclass · Answer

(A) Metals that are lower in the reactivity series can be reduced by hydrogen. Copper $(II)$ oxide $(CuO)$ is less reactive than hydrogen and can be reduced to metallic copper by heating in a stream of hydrogen gas: $CuO(s) + H_2(g) \rightarrow Cu(s) + H_2O(g)$. Magnesium,aluminium,and calcium are highly reactive metals,and their oxides cannot be reduced by hydrogen.

Which of the following oxides can be reduced to the metal by heating it in a stream of hydrogen?
