Solution

When an acid reacts with a metal hydrogencarbonate, then a salt, carbon dioxide gas and water are formed

$M e t a l h y d r o g e n c a r b o n a t e + A c i d \to s a l t + C a r b o n d i o x i d e + W a t e r$

For example, when dilute hydrochloric acid reacts with sodium hydrogen carbonate, then sodium chloride, carbon dioxide, and water are formed.

$N a H C O_{3} (s) + H C l (a q) \to N a C l (a q) + C O_{2} (g) + H_{2} O (I)$
