The following reaction $2\mathrm{Mg}+{\mathrm{O}}_2\to 2\mathrm{MgO}$ is an example of which reaction?

• The given reaction is $\underset{\mathrm{Magnesium}}{2\mathrm{Mg}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{\mathrm{O}\left(\mathrm{g}\right)}\to \underset{\mathrm{Magnesium}\mathrm{oxide}}{2\mathrm{MgO}\left(\mathrm{s}\right)}$
• It is an example of an oxidation reaction because in the above reaction, $\mathrm{Mg}$ is getting oxidized to form $\mathrm{MgO}$.
• Also, it is a type of combination reaction because magnesium reacts with oxygen to form a single product i.e. Magnesium oxide.

Hence, $2\mathrm{Mg}+{\mathrm{O}}_2\to 2\mathrm{MgO}$ is an example of oxidation and combination reaction.
