#Cu + Cl_2 => CuCl_2#; synthesis

Explanation:

Reactants:
Copper is not a diatom, but Chlorine is. This means that Chlorine must be written with a 2 in subscripts.

Products:
Copper will most likely have an oxidation number of +2; Chlorine has a number of -1.
Copper(II) Chloride exists in a ratio of #1:2#

You must keep watch for other diatoms and complex equations in more advanced chemistry; you will be expected to balance these.

It is a synthesis reaction because it has two reactants combining to form one product.
