A Combination Reaction or a Synthesis Reaction is a general category of a chemical reaction (the term usually refers to an inorganic chemical reaction), in which two or more reagents are chemically bonded together to produce a single product.

For example, the addition of sodium and chlorine to form sodium chloride or common table salt,

2Na_(s) + Cl_2(g) → 2NaCl_(s)

is a combination reaction.
