Give one example of a decomposition reaction which is carried out: (a) With electricity By applying heat

• When electricity is passed through acidified water it decomposes to Hydrogen and oxygen gas 2H2 O → 2H2 + O2
• By applying heat, thermal decomposition takes place 2NaHCO3(s) → CO2(g) + H2O(g) + Na2CO3(s)

Heating of baking soda is an example
