There are two Iron chlorides. Iron(II) chloride, in which iron is in +2 oxidation state, and Iron(III) chloride, in which iron is in +3 oxidation state.
The name gives the clue. If any chemical is described as '-ous' it has the lower oxidation state. If described as '-ic' , it has the higher oxidation state, Hence Ferrous chloride is 'Iron(II) chloride' ( FeCl2) Ferric chloride is 'Iron(III) chloride' ( FeCl3). Similarly with Nitric Acid and Nitrous Acid ( HNO3/HNO2) Sulphuric acid and Sulphurous Acid (H2SO4/H2SO3)
No, they have different formulas and have iron in different oxidation states. Ferrous chloride or Iron II chloride has the Fe2+ ion and the formula FeCl2 Ferric chloride or Iron III chloride has the Fe3+ ion and the formula FeCl3
+2 oxidation state
Iron(III) Chloride / Ferric Chloride / Iron Trichloride
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 oxidation state of iron in two moles or atoms of elemental iron is zero. If you mean iron (II), the oxidation state is +2.
most likely Magnesium-Chloride(MG?CL?) and Iron(FE?) The numbers depend on the oxidation states of iron and magnesium
Iron sulphide is an ionic compound. The Iron is in a +2 oxidation state and the sulphur is in a -2 oxidation state.
No, they have different formulas and have iron in different oxidation states. Ferrous chloride or Iron II chloride has the Fe2+ ion and the formula FeCl2 Ferric chloride or Iron III chloride has the Fe3+ ion and the formula FeCl3
+2 oxidation state
+2
Iron can exist in the body as ferrous or ferric, depending on what part of the biological process iron is in. For instance, iron in the plus two-oxidation state is "ferrous". Iron in the plus three-oxidation state is ferric.
Iron(III) Chloride / Ferric Chloride / Iron Trichloride
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, 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.
Iron has oxidation state of -2, in the Tetracarbonyl Ferrate ion
