Answer 1

Answer:

(1.) X-Baking soda

(Sodium hydrogen carbonate)

NaHCO3

(2.) 2NaHCO3--------->Na2CO3+H2O+CO2

(3.) Uses of sodium hydrogen carbonate (NAHCO3) :-

(a.) It is used in soda fire extinguisher.

(4.) Y-Washing soda

(Sodium carbonate deca hydrates)

Na2CO3

•When washing soda is treated with Water the following reaction takes place:-

Na2CO3+10H2O----------->Na2CO3.10H2O.
