Question

Give the chemical equation for the formation of sodium hydride.

Answer 1

Formation of Sodium hydride:

• When hydrogen gas is passed over sodium metal, it will lead to the formation of Sodium hydride.
• The balanced chemical reaction can be represented as:

$\underset{\mathrm{Sodium}}{2\mathrm{Na}\left(\mathrm{s}\right)}+\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Sodium}\mathrm{hydride}}{2\mathrm{NaH}\left(\mathrm{s}\right)}$
