Question

Metal compound a reacts with dilute hydrochloric acid to product 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.

Answer 1

i hope it was helpful.

Answer 2

Answer:-

As metal compound released is Calcium Chloride the gas evolved here is CO2. Hence metal A should be Calcium Carbonate. Hence the reaction between Calcium Carbonate and HCl is

CaCO3 (s) + 2HCl (Aq) → CaCl2( Aq) + CO2 (g) + H2O (l)
