Answer:

It replaces Br in MgBr2.

Explanation:

Hello!

In this case, when carrying out double displacement reactions, we need to take into account that cations and anions are switched; thus, when LiCl and MgBr2 react, since Li and Mg are the cations, Br and Cl switch as shown below:

[tex]2LiCl+MgBr_2\rightarrow 2LiBr+MgCl_2[/tex]

Thus, chlorine replace Br in MgBr2 to form MgCl2.

Best regards!
