Name the type of the following reaction:

Displacement reaction:

• It is a chemical reaction in which an element replaces another element in a compound and takes its place.
• The most reactive metal occupies the top position in the series whereas the least reactive metal is at the bottom of the series.
• When iron$\left(\mathrm{Fe}\right)$ reacts with copper sulphate$\left({\mathrm{CuSO}}_4\right)$, it forms ferrous sulphate$\left({\mathrm{FeSO}}_4\right)$ and copper$\left(\mathrm{Cu}\right)$.
• $\underset{\mathrm{iron}}{\mathrm{Fe}(\mathrm{s}})+\underset{\mathrm{ferrous}\mathrm{sulpphate}}{{\mathrm{FeSO}}_4\left(\mathrm{aq}\right)}\stackrel{}{\to }\underset{\mathrm{copper}\mathrm{sulphate}}{{\mathrm{CuSO}}_4\left(\mathrm{aq}\right)}+\underset{\mathrm{copper}}{\mathrm{Cu}\left(\mathrm{s}\right)}$
• The iron $\left(\mathrm{Fe}\right)$being higher reactive displaces the copper$\left(\mathrm{Cu}\right)$ which is lesser reactive from its compound$\left({\mathrm{CuSO}}_4\right)$
