Stoichiometry Help Needed
« on: September 24, 2006, 04:14:29 PM »
I forgot how to do this question:

 _Fe(OH)2 + _O2 + _H2O --> _Fe(OH)3
If 1 mole of O2 oxidizes Fe(OH)2 according to the reaction represented above, how many moles of Fe(OH)3 can be formed?
(A) 2 (B) 3 (C) 4
(D) 5 (E) 6

Could anyone just show me the steps on how to do this problem? Give me hints? Anything?

You need to balance it first.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

OK, I balanced it as:

4Fe(OH)2 + O2 + 2H2O --> 4Fe(OH)3

I get it.

Thanks, I kind of blanked out there...  :-X
