What is the ionic formula for iron oxide?

Answer 1

FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and

Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)

Answer 2

Fe2O3 Fe2O3

The roman numerals in Iron III Oxide represent the positive charge of the iron. The oxide has a negative two charge, so, in order to balance it all out, you need two iron and three oxide.

Fe+3 O-2

2Fe = +6 charge

3O = -6 charge

This balances it out.

Answer 3

The formula for iron oxide depends on if it is Iron (II) oxide, which would be FeO, or Iron (III) oxide, which would be Fe2O3.

Answer 4

The answer is FeO, not to be confused with Iron III oxide (Fe2O3).

Answer 5

FeO (iron II or ferrous oxide) , Fe2O3 (iron III or ferric oxide)

Answer 6

The formula for iron IV oxide is PbO2. Also known as lead dioxide, PbO2 is an insoluble powder and brown in color.

Answer 7

The ionic formula for iron oxide is Fe2O3. Iron has a +3 charge and oxygen has a -2 charge, so the formula balances to include two iron atoms for every three oxygen atoms.

Answer 8

FeO
