l think it's help you please mark me as brainiest

Answer 2

Baking soda (NaHCO3) on heatingproduces carbon dioxide (CO2), which extinguishes a burning matchstick. 


Washing soda, also known as sodium carbonate decahydrate, when its crystals are strongly heated, the water of crystallisation i.e. 10H2O completely evaporates leaving behind anhydrous sodium carbonate i.e. Na2CO3.


Na2CO3.10H2O → NaCO3 + 10H2O
