Answer:
The chemical formula of sodium carbonate (washing soda) is Na2CO3. When it is heated it undergoes a thermal decomposition reaction. This takes place above 500 degree C. The reaction of decomposition is
Na
2
CO
3
(s)→Na
2
O(s)+CO
2
(g)
The name of the first reaction product Na_2O is Sodium Oxide which is solid and used in glass making and the name of the second reaction product is Carbon Dioxide which is a gas
On calculating this reaction one might get answer 2.08 litres but as Na
2
CO
3
is soda ash and it does not decomposes at STP And CO
2
does not evolved
So the answer will be zero litres
