250 g iron (III) oxide is equal to 1,565 moles.
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
The balanced chemical equation for the reaction of oxygen with iron to form iron (III) oxide is: 4 Fe + 3 O₂ → 2 Fe₂O₃. This equation shows that four moles of iron react with three moles of oxygen to produce two moles of iron (III) oxide.
The balanced equation for the reaction of solid iron with gaseous oxygen to form solid iron(III) oxide is: 4 Fe (s) + 3 O₂ (g) → 2 Fe₂O₃ (s). This equation indicates that four moles of iron react with three moles of oxygen to produce two moles of iron(III) oxide.
The chemical formula for Iron III oxide is Fe2O3. It is composed of two iron atoms bonded to three oxygen atoms in a compound.
To find the moles of formula units in 5.67 g of iron III sulfate, you first need to calculate the molar mass of Fe2(SO4)3. The molar mass is 399.9 g/mol. Then, divide the given mass by the molar mass to find the number of moles. In this case, 5.67 g / 399.9 g/mol = 0.0142 moles of formula units.
250 g iron (III) oxide is equal to 1,565 moles.
Formula of 3 types of Iron oxides: Iron(II) oxide= FeO Iron(III) oxide= Fe2O3 Iron(II,III) oxide= Fe3O4
Iron oxide is too general a term. The formula for Iron (II) Oxide is FeO and the formula of Iron (III) Oxide is Fe2O3
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)

The chemical formula for iron (lll) oxide is Fe2O3.
The chemical formula for iron (III) oxide is Fe2O3, where Fe represents iron and O represents oxygen.
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
One formula unit of iron III sulfate consists of one iron atom, three sulfur atoms, and 12 oxygen atoms. To calculate the number of formula units in 0.671 moles of iron III sulfate, you first need to determine the molar mass of the compound, then use the Avogadro's number (6.022 x 10^23) to convert moles to formula units.
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
Iron II oxide: FeO Iron III oxide: Fe2O3
