Solution

The correct option is B

CO2


When a dilute hydrochloric acid reacts with sodium carbonate, then sodium chloride, CO2 and water are formed.

Na2CO3(s)+2HCl(aq)→2NaCl(aq)+CO2(g)+H2O(l)

The carbon dioxide gas is formed in the form of brisk effervescence(the rapid escape of small bubbles of gas from the liquid).
