"MgBr"_2 + "Cl"_2"rarr"MgCl"_2 + "Br"_2"

Explanation:

This is a single replacement (double replacement) reaction involving halogens instead of metals.

Chlorine and bromine are both halogens in group 17/VIIA. The reactivity of the halogens decreases from top to bottom in the group. Chlorine is above bromine, therefore it is more reactive and will replace bromine in "MgBr"_2".
