Question

Give one example of a decomposition reaction which is carried out;

With electricity.

Answer 1

Decomposition reaction

Decomposition reactions are reactions in which a single substance splits into two or more simple substances under suitable conditions.

$\mathrm{AB}\to \mathrm{A}+\mathrm{B}$

Example of decomposition reaction carried out with electricity:

The decomposition of water(H₂O) into oxygen(O₂) and hydrogen(H₂) due to the passing of electric current through it is called the electrolysis of water.

$2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\stackrel{\mathrm{electric}\mathrm{current}}{\to }2{\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)$

Thus, the electrolysis of water is an example of a decomposition reaction with electricity.
