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.

Answer

When a metal compound reacts with an acid it gives metallic salt, carbon dioxide and water. The carbon dioxide \((CO_2)\) so evolved extinguishes the burning candle as \(CO_2\) is a non supporter of combustion. The metallic compound \(A\) in the reaction is \(CaCO_{3}\) which reacts with \(HCl\) to form a metallic salt \((CaCl_{2})\), \(CO_{2}\) and \(H_{2}O\). The balanced chemical equation for the reaction is:
\(CaCO_{3} + 2 HCl → CaCl_{2} +CO_{2} + H_{2}O\)
