Question

if LiCl and MgBr2 were to enter into a chemical reaction which member of MgBr2 will chlorine replace?

Answer 1

It replaces Br in MgBr2.

Step-by-step 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:

`2LiCl+MgBr_2\rightarrow 2LiBr+MgCl_2`

Thus, chlorine replace Br in MgBr2 to form MgCl2.
