Question

In the reaction of copper oxide and hydrogen, copper oxide is reduced to copper.

• A. True
• B. False

Answer 1

The correct option is A True

1. The oxides are reduced to corresponding metals when hydrogen gas is passed over heated metal oxide.
2. The reaction between copper oxide and hydrogen is as follows;

$\underset{\mathrm{Copper}\mathrm{oxide}}{\mathrm{CuO}\left(\mathrm{s}\right)}+\underset{\mathrm{hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{copper}}{\mathrm{Cu}\left(\mathrm{s}\right)}+\underset{\mathrm{water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)}$

In this reaction, hydrogen reduces copper oxide into copper.

Therefore, the given statement is true.
