Sodium hydrogencarbonate on reaction with acetic acid releases carbon dioxide gas.
NaHCO3 + CH3COOH → CH3COONa + H2O + CO2
Test for carbon dioxide:
The presence of carbon dioxide can be tested by bringing a burning splinter near the mouth of the cylinder containing carbon dioxide – it gets extinguished.
If carbon dioxide is passed through limewater, it turns milky white.
Ca(OH)2 + CO2 → CaCO3 + H2O

co2 is the answer
Carbon dioxide is colorless. At low concentrations the gas is odorless however, at sufficiently-high concentrations, it has a sharp, acidic odor. At standard temperature and pressure, the density of carbon dioxide is around 1.98 kg/m3, about 1.67 times that of air.
