This is your answer
Explanation:
CHEMISTRY
Metal compound A reacts with dilute hydrochloric acid to produce effervescence. The gas evolved extinguishes a burning candle. Write a balanced chemical equation for the reaction if one of the compounds formed is calcium chloride.
When a metal compound A on reacting with hydrochloric acid shows effervescence which shows the evolution of carbon dioxide gas and it is confirmed by putting off the candle flame.
So metal compound A is a carbonate of calcium which on reacting with HCl gives calcium chloride and carbon dioxide as gas along with water.

(s) + 2HCl(aq) → CaCl
