Sodium Bicarbonate on decomposition produces Carbon dioxide gas and Water vapors.

2 NaHCO ₂ → Na ₂ CO ₃ (s) + CO ₂ (g) + H ₂ O (g)

Explanation:

Let suppose you burn 168 g (2 moles) of NaHCO₃, a gas will produced and product is left behind. On measuring the product formed it will be almost equal to 105 g. This shows that the product is Na₂CO₃ and 1 mole of it is being produced after decomposition of sodium bicarbonate.
