Question

Give a balanced molecular equation for production of CO2 by action of dil.H2SO4 on sodium carbonate​

Answer 1

Sissy Ig the question needs to be modified a bit when Sulphuric acid reacts with Sodium Carbonate it doesn't yield $\sf CO_2$ rather it must be sodium bicarbonate then the reaction would be as per the criteria.

$\sf NaHCO_3 + H_2SO_4 \rightarrow NaHSO_4 + H_2O + CO_2$
