First of all, what is a chemical reaction? Is it known to you? If not, then you should know that a chemical reaction is the process of breaking the chemical bonds of the reacting substances (reactants) and making new bonds to form new substances (products).

For example, H2 + Cl2 ------> 2HCl

Now, change of state refers to the process of conversion of one state of matter to another state of matter. In many chemical reactions, a change of state is observed. The reaction might start with gaseous or liquid reactants but it will end up with a solid product and vice-versa.

Example : Ammonia gas reacts with hydrogen chloride gas to produce solid ammonium chloride.

NH3 (g) + HCl (g) = NH4Cl (s)
