when the carbonate is heated in absence of air then the CO2 is produced as the byproduct .

Add some acid...
put the mixture in water and add hydrochloric acid the carbonate becomes decomposed when no further bubbles appear by adding hydrochloric acid then heat the mixture till dryness and get the solid sodium chloride.
Carbon dioxide.
Add an acid. The hydrogen ion will combine with carbonate to make H2CO3 which will decay into water and carbon dioxide causing rapid bubbling. Therefore, if you add an acid to a salt in solution and rapid bubbling occurs, then it is a carbonate salt.
No reaction occurs
co2
you get the right answer on webassign
NaCl+H2CO3
EXPLOSION that is what will happen.
you add hcl and caco3
A large amount of heat is released when strong acids are mixed with water. Adding more acid releases more heat. If you add water to acid, you form an extremely concentrated solution of acid initially. So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container! If you add acid to water, the solution that forms is very dilute and the small amount of heat released is not enough to vaporize and spatter it.
