The reaction of ammonia and hydrogen chloride gas:

NH3(s)+HCl(g)→NH4Cl(s)+Energy

is a synthesis reaction.

A synthesis reaction, also known as a combination reaction, involves the combination of two or more substances to form a new compound. In this case, ammonia (NH3) and hydrogen chloride (HCl) combine to form ammonium chloride (NH4Cl).
