Expert Answer:

The reaction between vinegar and baking soda can be written as a double displacement reaction if carbonic acid (H2CO3) is considered a product:

HCH3O2(aq) + NaHCO3(aq) NaC2H3O2(aq) + H2CO3(aq)

However, carbonic acid readily decomposes into carbon dioxide and water,

H2CO3(aq) CO2(aq) + H2O()

and the carbon dioxide can escape from the solution as a gas.

The combined equation is

HC2H3O2(aq) + NaHCO3(aq) NaC2H3O2(aq) + H2O() + CO2(g)
