______________ soda on heating decomposes to sodium carbonate, water and carbon dioxide .
2NaHCO3(s)⏟(Sodiumbicarbonate)→∆Na2CO3(s)⏟(Sodiumcarbonate)+CO2(g)⏟(Carbondioxide)+H2O(l)⏟(Water)
Therefore, Baking soda on heating decomposes to sodium carbonate, water and carbon dioxide.

(b) A nitrate which on heating decomposes into dinitrogen oxide [nitrous oxide] and steam.
(c) A nitrate which gives off oxygen and nitrogen dioxide when heated.
Name:
(a) A carbonate which does not decompose on heating.
(b) A nitrate which produces oxygen as the only gas.
(c) A compound which produces carbon dioxide on heating
