Question

The oxides of metals which are least reactive can be reduced to their respective metals by simple heating.

• A. True
• B. False

Answer 1

The correct option is A True

The oxides of the metals which are least reactive and lie below hydrogen in the activity series can be reduced into metallic form by heating alone.

For example, mercury oxide is reduced to molten mercury by simple heating. The reaction is given below:

$2\text{HgO}\text{(s)}\underrightarrow{\text{Heat}}2\text{Hg}\text{(l)}+{\text{O}}_2\text{(g)}$
