Question

Which type of reaction is represented by the chemical reaction $\mathrm{Mg}\left(\mathrm{s}\right)+{\mathrm{CuSO}}_4\left(\mathrm{s}\right)\to {\mathrm{MgSO}}_4\left(\mathrm{s}\right)+\mathrm{Cu}\left(\mathrm{s}\right)$.

Answer 1

Type of reactions:

Combination reaction - Two or more compounds combine to form one compound.

Decomposition reaction - A complex molecule breaks down to make simpler ones.

Precipitation reaction - Two solutions of soluble salts are mixed resulting in an insoluble solid (precipitate) forming.

Neutralization reaction - An acid and a base react with each other and the product of this reaction is salt and water.

Combustion reaction - Oxygen combines with a compound to form carbon dioxide and water.

Displacement reaction - One element takes place of another element in the compound.26c04e12841ead283306bf3

Chemical reaction:

$\mathrm{Mg}\left(\mathrm{s}\right)+{\mathrm{CuSO}}_4\left(\mathrm{s}\right)\to {\mathrm{MgSO}}_4\left(\mathrm{s}\right)+\mathrm{Cu}\left(\mathrm{s}\right)$

As a less reactive substance(Cu) is displaced by a more reactive substance(Mg).

Therefore, the above chemical reaction is a displacement reaction.
