A meaningless question. Because an equation relates the interaction of TWO or more substances, while this question mentions only ONE (namely Iron).
2Fe + AlSO4
Hydrochloric acid + Magnesium = hydrogen + Magnesium chloride
•Redox reactions can cause a change in volume •2Fe + 1.5 O2 > Fe2O3
C + O2 --> CO 3CO + Fe2O3 --> 2Fe + 3CO2
The formula for iron (III) oxide is FeCl3, whether the formula is in a balanced equation or anywhere else where the formula is properly used.
There are two possible equations as iron is capable of forming two different oxides: O2 + 2Fe --> 2FeO 3O2 + 4Fe --> 2Fe2O3
2Fe(s) + 2H2O(l) + O2(g) ==> 2Fe2+(aq) + 4OH-(aq)---------------------------------------Iron rust is hydrated Fe2O3 and Fe(OH).Fe(OH)3.4Fe + 3O2 = 2Fe2O3.

Oxidation is the recombination of atoms of one molecule with oxygen. An example might be the rusting of iron: 2Fe(s) + 3O2(g) --> 2Fe2O3(s) Therefore, oxidation is chemical reaction.
2Fe + O2 --> 2FeO iron (II) oxide ( ferrous oxide 3Fe +2O2 -->Fe3O4 iron (II, II) oxide (ferric ferrous oxide) 4Fe + 3O2 --> 2Fe2O3 iron(III) oxide, (ferric oxide)
The molar and equivalent mass of Mohr salt is 392,14; the chemical formula is: (NH4)2Fe(SO4)2.6H2O.
Two iron atoms
One is Shrek element B while the other two are Dreck elements C and A
Formula: (CH3COO)2Fe
Formula: (CH3COO)2Fe
that means 2 iron atoms
