CrCl6(AQ) + Mg(S) -> MgCl2(AQ) + Cr(S)
CrCl6(AQ) + 3Mg(S) -> 3MgCl2(AQ) + Cr(S)
Make sure both sides are balanced.
The 3 in front of both of the Mg's is be cause 3*2=6, and you have to put a 3 in front to balance it out with the CrCl6,and the Mg's need to be balanced too so you another 3 in front of the Mg.
Now the reaction is balanced.

CaOH not Ca(OH)2 and you need 6, not 3...
