Answer 2

Washing soda is sodium carbonate containing 10 molecules of water of crystallisation.It is called as sodium carbonate decahydrate.

Sodium carbonate (also known as washing soda, soda ash and soda crystals, and in the monohydrate form as crystal carbonate), Na2CO3, is the water-soluble sodium salt of carbonic acid. It most commonly occurs as a crystalline decahydrate, which readily efflorescence to form a white powder, the monohydrate.

1.2NH3 +H2O + CO2 gives (NH4)2CO3

2. (NH4)2CO3 + H2O + CO2 gives 2NH4HCO3

3. NH4HCO3 + NaCl gives NaHCO3 + NH4Cl

i am not sure with the formula
