It contains only two elements. Fe shows +3 number. Chlorine shows -1 as the oxidation number.
The oxidation number for iron in FeBr3 is 3+.
In FeO the oxidation number of iron is 2+ and the oxidation number of oxygen is 2-.
Na2[Fe(CN)5NO]·2H2O, the oxidation number of iron is +3.
This is iron II, III oxide and features iron in both the 2+ and 3+ oxidation states.
No, that is not possible for Chlorine. Some elements have more than one oxidation number, such as Iron, Mercury, Copper, etc, but Chlorine only wants to gain one electron. If it had a -2 charge, it would not be stable, so that would never happen.
No, rusting is a term reserved for the oxidation of iron or iron alloys. Processes similar to rusting involve the oxidation of other metals. Although chlorine can be oxidized, it is not considered rusting when it happens, especially considering that chlorine is a nonmetallic gas.
+3 is the oxidation no of iron(III)

No, rust is another term for oxidation, therefore, rust is Iron oxide. Also, Chlorine only reacts with Iron when the Iron is heated, this makes Iron(III) chloride.

The possible oxidation numbers for iron cations are +2 and +3. Oxygen in oxyanions is usually assigned an oxidation number of -2, producing a total negative charge of -14 for the seven oxygen atoms in a dichromate anion. If the iron cation has an oxidation number of +2, the two chromium atoms must have a total oxidation number of +12, which is possible when each chromium atom has an oxidation number of +6. An iron (III) cation would require the chromium atoms to have a non integral charge, which is not possible since electrons with half charges are not known. Therefore, the oxidation number of iron in the compound is +2 and the oxidation number for chromium is +6.
I am going to assume you meant ferrous oxide. Ferrous oxide is also known as Iron(II) oxide and has the formula unit FeO. The oxidation number of iron in iron(II) oxide is +2.
Usually, oxygen has an oxidation of -2 (that is unless in a compound with peroxides or halogens).
