Though a nuclear reaction could be the answer to this question, it is more probable that a chemical reaction is the change of one or more substances into a different substance or different substances. (The changes in nuclear reactions normally include only a single element.)Examples abound. The elements hydrogen (H2) and oxygen (O2) combine in a chemical reaction to form water (H2O) in the following familiar reaction:2H2 + O2 => 2H2OWhen ozone (O3) breaks down spontaneously, it forms oxygen in the following reaction:2O3 => 3O2

They could be chemical or (thermo)nuclear processes.
