Here's one last equation I can't balance:

Al{subscript 2}(SO{subscript 4}){subscript 3} + ZnCl{subscript 2} -> AlCl{subscript 3} + ZnSO{subscript 4}
Please help, and thanks again.

Response
Al2(SO4)3 + 3ZnCl2 ---> 2AlCl3 + ?___ZnSO4

Why do you have "?____" before the ZnSO4?

What is your thinking? What goes in the blank?
I would guess that a 3 goes there.
