The oxidation number of iron in this compound is 3. The oxidation numbers of the total oxygen atoms and the total iron atoms must be the same in a neutral compound. There are three oxygen atoms, giving a total for oxygen of 3 X 2 = 6. There are only two iron atoms; therefore, each one must have an oxidation number of 6/2 = 3.
100 will be oxidation no.in Fe2O3.
it is +2 it is also done by causing rust
+3 for Fe; -2 for O
O = 2-, Fe = 3+.
+3 for Fe and -2 for O.
Usually, oxygen has an oxidation of -2 (that is unless in a compound with peroxides or halogens).
100 will be oxidation no.in Fe2O3.
That compound is Iron Oxide. It contains iron and oxygens.
it is +2 it is also done by causing rust
+3 for Fe; -2 for O
O = 2-, Fe = 3+.
+3 for Fe and -2 for O.
The oxidation number for Fe would be 3+ and for oxygen it would be 2-. This would be Fe2O3
Fe2O3. +3 for Fe, -2 of O.
Oxidation numbers in Fe2O3 are respectively: Fe => +3 and O => -2
Because the other iron oxides Fe3O4, Fe2O3 would have the same name. In order for this to not happen you should indicate the oxidation number of iron.
- Oxygen in almost all compounds has an oxidation # of (-2). - Your solving for the oxidation # of Fe so make this (X) - Creating an equation with what you know: There are 2 Fe in the compound, so it would be 2X. There are 3 O in the compound, so it would be (-2 * 3) = -6 2X - 6 = 0 -Do the algebra: 1) 2X = +6 2) X = +6/ 2 3) X = Fe = +3 oxidation number
