Answer 1

NaHCO3+CH3COOH->CH3COONa+H2O+CO2

In this reaction CO2 gas is released which help in white washing....

Answer 2

Answer:

In this reaction, carbon dioxide gas is produced that escapes as bubbles. Since these 'bubbles are heavier than air, they will get collected on the surface of the container or may even overflow.

It is typically a two-step, double displacement reaction which first produces Carbonic acid. Now, as it is unstable, it undergoes decomposition to produce carbon dioxide. The chemical equation of the reaction is as follows.

NaHCO3 + HC2H3O2 → NaC2H3O2 + H2CO3.
