1. You don't need me to do this. Balance it and add the coefficients. Or if you're having trouble, explain the problem.

No. You need the practice. Here is how you start. Right off the bat I see 3 SO4 on the left so we stick a 3 for CaSO4. That takes care of a chunk. I would balance Al next, then count up H and balance them.
