It has both +3 and +2 oxidation states
Iron has both +2 and +3 oxidation states.
Fe3O4 can be considered to be 1:1 mixture of FeO and Fe2O3. Oxidation number in FeO: +2 for Fe and -2 of O Oxidation number in Fe2O3: +3 for Fe and -2 of O
the valance number of iron is 3 why,becouse in the formula after iron there is 3.the question ask you what is the valency of Fe3O4....
No. it can't be fractional. However you can get fractional answers uch as Fe in Fe3O4 where the average oxidation state is 2.666.... You need to know something about the structure that will tell you what oxidation numbers of the Fe in this case two Fe with +3 and one Fe with +2 in each formula unit.
a)3 b)2 c)1 d)4 Fe is the transitional metal K3[Fe(CN)6] , we know that Potassium, K, has an oxidation number of +1 The oxidation number of CN= -1, so 6*CN has an oxidation number of -6 so therefore Fe - 6 = -3 Fe = -3 + 6 = +3 The oxidation number of Fe is +3. so A
+2 O.S. of Fe

+2 O.S. of Fe
It contains only two elements. Fe shows +3 number. Chlorine shows -1 as the oxidation number.
oxidation state of Fe in FeCl3 is +3. Cl has oxidation number -1 in this case Fe share 3 electrons with Cl so its oxidation state is +3.
+2 for Fe, -2 for O
This is possible because in the crystaline solid magnetite(Fe3O4), the Fe atoms are bonded to oxygen in a complex fashion that is a combination of Fe in its two oxidation states (+3 and +2)
+3 for Fe -2 for S
Fe has an oxidation number of+2 in ferrous salts+3 in ferric saltsAs Br has an oxidation number of -1 in bromide, only two salts of Fe with Br are possible:FeBr2 = ferrous bromideFeBr3 = ferric bromideand FeBr DOES NOT EXIST
The balanced equation is 3 Fe3O4 + 8 Al -> 4 Al2O3 + 9 Fe. Therefore, the coefficient of Fe is 9.
