Question

What happens when Magnesium reacts with hot water?

Answer 1

Metals reacts with water (${\mathrm{H}}_2\mathrm{O}$) and results in the formation of metal oxide ($\mathrm{MO}$) and Hydrogen (${\mathrm{H}}_2$).

Magnesium ($\mathrm{Mg}$) interacts slowly with cold water (${\mathrm{H}}_2\mathrm{O}$), but quickly with hot boiling water (${\mathrm{H}}_2\mathrm{O}$), to produce Magnesium oxide ( $\mathrm{MgO}$ ) and Hydrogen (${\mathrm{H}}_2$). The chemical reaction is as follows.

$\underset{\mathrm{Magnesium}}{\mathrm{Mg}\left(\mathrm{s}\right)}+\hspace{0.17em}\underset{\underset{\mathrm{water}}{\mathrm{Boiling}}}{{\mathrm{H}}_2\mathrm{O}}\left(\mathrm{l}\right)\underset{}{\to }\underset{\underset{\mathrm{oxide}}{\mathrm{Magnesium}}}{\mathrm{MgO}\left(\mathrm{s}\right)}+\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}$
