pass the gas through lime water. if lime water turns milky then it is carbon dioxide.

The chemical equation for the overall reaction is:
NaHCO3(s) + CH3COOH(l) → CO2(g) + H2O(l) + Na+(aq) + CH3COO-(aq)
The carbon dioxide escapes the solution as bubbles.
The bubbles are heavier than air, so the carbon dioxide collects at the surface of the container or overflows it. In a baking soda volcano, detergent usually is added to collect the gas and form bubbles that flow somewhat like lava down the side of the 'volcano'. A dilute sodium acetate solution remains after the reaction.
If the water is boiled off of this solution, a supersaturated solution of sodium acetate forms. This "hot ice" will spontaneously crystallize, releasing heat and forming a solid that resembles water ice.
The carbon dioxide released by the baking soda and vinegar reaction has other uses besides making a chemical volcano. It can be collected and used as a simple chemical fire extinguisher. Because carbon dioxide is heavier than air, it displaces it. This starves a fire of the oxygen needed for combustion.
