## Question

*X* if X is a number, that means it's subscript

EX: F *2* + S --> SF *6* becomes 3F *2* + S --> SF *6*

There's only one I can't get:

AlBr*3* + K*2*SO*4* --> KBr + Al*2*(SO*4*)*3*

anyone?

1. get the Br's to equal

2. get the SO*4*'s to equal

3. get the Al's to equal

4. get the Br's to equal once more

5. the K's shall now be equal

does that help?

Just so you know, you can put subscripts in posts. Ex:

O{sub}2{/sub} becomes O2 when you replace {} with []

I would have helped with the problem, but sf's already got you covered with the order of Bromine-Sulfate-Aluminum-Bromine. I'm confirming that's right, and pointing the sub code out to you for future reference.

yep! thanks! :D

EX: F2+S --> SF6 becomes 3F2+S --> SF6

There's only one I can't get:

AlBr3+K2SO4 --> KBr+Al2(SO4)3

there we go...
