Consider the reaction: $\mathrm{KBr}\left(\mathrm{aq}\right)+{\mathrm{AgNO}}_3\left(\mathrm{aq}\right)\to {\mathrm{KNO}}_3\left(\mathrm{aq}\right)+\mathrm{AgBr} \left(\mathrm{s}\right)$. This is an example of

Identify and write the type of reaction represented by following equations.

$2{\mathrm{FeSO}}_4\to {\mathrm{Fe}}_2{\mathrm{O}}_3+{\mathrm{SO}}_2+{\mathrm{SO}}_3$.
