If it existed the formula would be Cu2O3
The correct chemical formula for copper oxide is Cu2O for copper(I) oxide (cuprous oxide) and CuO for copper(II) oxide (cupric oxide).
The chemical formula for manganese(III) oxide is Mn2O3.
copper oxide- CuO hydrogen sulphate- h2SO4
The chemical formula for antimony III oxide is Sb2O3.
The chemical formula for copper oxide is CuO.
The correct chemical formula for copper oxide is Cu2O for copper(I) oxide (cuprous oxide) and CuO for copper(II) oxide (cupric oxide).
Phosphorus(III) oxide has the formula P2O3 but it exists as the molecule of P4O6
The chemical formula for manganese(III) oxide is Mn2O3.
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
copper oxide- CuO hydrogen sulphate- h2SO4
The balanced formula for copper reacting with oxygen to form copper oxide is: 4Cu + O2 -> 2Cu2O.
Formula: V(IO3)3
The chemical formula for antimony III oxide is Sb2O3.
The chemical formula for copper oxide is CuO.
The correct formula for copper(I) cyanide is CuCN.
Nickel(II) Oxide = NiO Nickel(III) Oxide= Ni2O3
The formula for cuprous oxide is Cu2O. The formula for copper is just Cu, although many copper items are not pure copper.
