Expert Answer
In some reactions, a change of a state is observed. The reaction starts with solid or liquid reactants and ends up with gaseous products and vice versa.
Example: Ammonia gas reacts with hydrogen chloride gas to form ammonium chloride which is in a solid state.
NH3(g) + HCl(g) → NH4Cl(s)
