Iron (II), it is a transition metal and you need to indicate its oxidation state

so SO4=-2
multiply by 3
you get -6
iron=+3 in this case
Iron (III)

I could link you to the thing called the "Chemistry Cruncher".
No more problems with this badboy.

procrastinating uses anything. i used to decide to clean my house at midnight instead of studying. it just so happens a computer game is fun so you would probably choose to do something fun over something not fun.
though i knew i had a problem because it was cleaning for gods sake. just sit down and fucking read the lame boring book that cost me close to $200. fucking college. so little is even needed from it.
