Answer 1

Hey friend ☺

Here is your answer

The name of the compound is sodium carbonate (Na2CO3) and the gas produced is carbon dioxide gas (CO2)

CHEMICAL EQUATION :

Na2CO3+H2SO4=>Na2SO4+CO2+H2O

HOPE THIS HELPS YOU ☺

Answer 2

The compound A is CaCo3 (Calcium Carbonate)

The equation is

CaCo3+H2So4 = CaSo4+Co2+H2O
