Question

Hydrogen reacts with metal oxides to give the corresponding metals.

• A. True
• B. False

Answer 1

The correct option is A True

The reaction of Hydrogen with metal oxides: Hydrogen can remove Oxygen from metal oxides such as Zinc oxide$\left(\mathrm{ZnO}\right)$, Copper oxide$\left(\mathrm{CuO}\right)$, and Lead oxide$\left(\mathrm{PbO}\right)$ to form the corresponding metals and water because H₂ is a strong reducing agent.

Example- The reaction of Hydrogen with Zinc oxide:

• Hydrogen reacts with Zinc oxide$\left(\mathrm{ZnO}\right)$ to form Zinc $\left(\mathrm{Zn}\right)$ metals and water.

$$\begin{gathered} {\mathrm{H}}_2\left(\mathrm{g}\right)+\mathrm{ZnO}\left(\mathrm{s}\right)\to \mathrm{Zn}\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right) \\ \mathrm{Hydrogen}\mathrm{Zinc}\mathrm{oxide}\mathrm{Zinc}\mathrm{Water} \end{gathered}$$

• This is also an example of a red-ox reaction.

Therefore the given statement is true.
