Death By Homework

Hot damn, giraffe! For the love of sugar-free Jello, I can't get this to work out:

Balance the chemical reaction:

FeSO₄ + K₂Cr₂O₇ + H₂SO₄ ---> Fe₂(SO₄)₃ + K₂SO₄ + H₂O

It's a little late to beg for help, so I'm just going to keep staring at it until it's time to go to school. I think I can smell my brain frying.

I do miss that beautiful thing called sleep.


Edit:
I was getting too frustrated to think so I ate some Jello. I came back and worked out an organized method for approaching the problem. Thirty minutes later, the solution showed itself. The feeling of getting a problem right after working on it for hours is like nothing else. Well...almost (S-K not included).

The magic answer:

6FeSO₄ + K₂Cr₂O₇ + 7H₂SO₄ ---> 3Fe₂(SO₄)₃ + K₂SO₄ + 7H₂O

It probably wasn't even supposed to be that hard. Brain decay. :(
