Fe3O2. But it's not right! Oxygen forms a 2- ion and iron can be 2+ or 3+. So the formulae of iron oxide can be FeO or Fe2O3.
The chemical formula for iron(II) chromate is FeCrO4.
The chemical formula of iron nitrate are Fe(NO3)2 and Fe(NO3)3.
The chemical formula for Iron(II) Chloride ( ferrous chloride) is FeCl2.
The chemical formula for iron(II) phosphide is Fe3P2. It is composed of two phosphorus atoms for every three iron atoms.
The chemical formula for iron(II) nitrate is Fe(NO3)2. It is a compound formed from an iron ion with a +2 charge and two nitrate ions, each with a -1 charge.
The chemical formula for iron(II) sulfate is FeSO4.
2 Magnesium OR Iron atoms to 1 Silicon, 4 Oxygen atoms. A formula of (Mg, Fe)2 Si O4
The chemical formula for magnetite is Fe3O4, indicating the presence of iron (Fe) and oxygen (O) atoms in a 2:3 ratio. In contrast, the chemical formula for hematite is Fe2O3, revealing a 2:3 ratio of iron (Fe) to oxygen (O) atoms. This difference in composition accounts for their distinct properties and colors.
The chemical formula for the oxygen in the air is O2, where the 2 should be a subscript.
The chemical formula for iron(II) chromate is FeCrO4.
The chemical formula for iron (II) sulfate is FeSO4.
The chemical formula of iron nitrate are Fe(NO3)2 and Fe(NO3)3.
The chemical formula for iron(II) acetate is Fe(CH3COO)2.
The chemical formula for iron II acetate is Fe(C2H3O2)2.
The chemical formula for Iron II hypophosphite is Fe(H2PO2)2.
The chemical formula for Oxygen is 02 (with a small 2).
The chemical formula for iron(II) phosphide is Fe3P2. It is composed of two phosphorus atoms for every three iron atoms.
