Give an example of a chemical change characterized by its physical state.

Asked by Topperlearning User 28th September 2016, 10:40 AM
Answered by 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)
