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?
