Solution

Understanding the chemical reaction:

Calcium carbonate reacts with dil hydrochloric acid to form calcium chloride and carbon dioxide is released as a by-product.

The gas evolved as carbon dioxide and is responsible for extinguishing the burning candle.

The balanced chemical equation to demonstrate the above-mentioned explanation can be given as:

Therefore, here the metal compound A is calcium carbonate and the effervescent is carbon dioxide.
