Short Note

In certain reaction a change of state is observed i.e. solid to liquid, liquid to gas etc. – State the change of state of the products – to give the respective reactant.

$\ce{2H2O ->[electric][current] 2H2 + O2}$

#### Solution

Decomposition of water

$\ce{2H2O[l]\underset{\text{current}}{->} \underset{\text{oxygen}}{2H2[g]} + O2[g]}$
