Explanation:
The acetic acid release a proton to water, to produce acetate and hydronium.
This is a weak acid.
The sulfuric acid release 2 protons to water to produce sulfate and hydronium.
This acid is considered as strong, but it is only strong in the first dissociation. The second dissociation is weak, with a Ka.
Carbonate takes a proton from water, to become bicarbonate (In this case, the carbonate behaves as a base).
Bicarbonate release a proton to ammonia, to make ammonium and carbonate anion.
Amonium cation release a proton to the hydroxide to make ammonia and water.

Explanation:
because in air the particles are moving very fast and jar of coffee has hot particles which kinetic energy is also more so that's why it's particles move faster and gets mixed with air and smell is coming from far away
