So... Hello there.
I've got a Chemistry final tomorrow, and had a quick question, here it is:

if you have a reaction, say

 MgBr₂ + Cl₂ ---->

This is obviously a Single Replacement reaction or will be, but is there a set way in which the 2nd half will be set up? IE: AB + C --> CA + B   always, no matter what in any single replacement reaction it will be set up like that. If there is, what is it, and what would it be for Double Replacement Reactions?

thanks a lot, Nate

You mean AB + CD -> AD + CB? 

That's usually the equation I see representing double replacement reactions.

Ah, ok. And the equation for a single replacement is AB + C --> AC + B?

Yup.
