Question

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 compound formed is calcium chloride​

Answer 1

Answer: CaCO3

Explanation: CaCO3+HCl-----CaCL2+H2O+CO2

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)
