One element an one compound combine to give a product. For example 2CO + O2 ——heat——-> 2Co2.

Two or more compounds combine to give a product. For example NH3+ HCl ———-> NH4Cl.

Decomposition reaction definition :

A reaction in which a compound breaks up into two or more simple substances either by application of heat or electricity is called decomposition reaction.

Due to decomposition reactions :

A compound can break up to form two or more elements. For example 2HgO → 2Hg +O2 .

A compound can break up to form both elements and compounds. For example 2KNO3 → 2KNO2 + O2
