Answer:

Explanation:

Metal compound A = CaCO3

Gas evolved will be = CO2

When calcium carbonate reacts with hydrochloric acid, the gas so produced is carbon dioxide gas with an effervescence. As we all know, that the gas carbon dioxide is also used as a fire extinguisher. Hence, it extinguishes the burning candle. Therefore, the metal compound A is calcium carbonate. The balanced chemical equation for the reaction if one of the compounds formed is calcium chloride will be -

CaCO3 + 2HCl --- CaCl2 + CO2 + H2O
