Combination reaction definition :
In simple words, a reaction in which two or more substances combine to form a single substance is called combination reaction.
In combination reactions:
Two elements combine to form a compound (also called synthesis). For example Fe + S ——-> FeS.
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
