Yes. A reaction does take place in neutralisation.
There is no specific thing. The chemical reaction is a result of the alkaline baking soda and the acidic vinegar neutralising each other.
Sulphurous acid is not a reaction (chemical or physical); the sulphurous acid (H2SO3) is a chemical compound.

This is a chemical reaction (dito change).

acid base reaction
If you add more baking soda to a vinegar (acetic acid) and baking soda (sodium bicarbonate) mix there will only be a further reaction if there is more acetic acid available to react with the baking soda. If the acid was used up by the first amount of baking soda no further reaction can occur.
Not a chemical reaction, but the formation of a water solution of hydrofluoric acid.
you get a chemical reaction.
