Take two test tubes , label them as A and B. Then take about  2 mL of dilute HCl to both test tubes .Then pass the gas produced  in each case through  lime water .Lime water turns milky.This shows that the gas produced is Carbon dioxide.

Metal carbonate/Metal Hydrogen carbonate+Acid?Salt+Carbon dioxide+water
