It depends on whether O2 is present. If not the formula would be Fe(II)tannate, if oxygen is present it would be Fe(III)tannate because air readilly oxidizes Fe(II) to Fe(III).
Formula of 3 types of Iron oxides: Iron(II) oxide= FeO Iron(III) oxide= Fe2O3 Iron(II,III) oxide= Fe3O4
The formula for iron(II) bromide is FeBr2.
The formula for Iron(II) Fluoride is FeF2.
The chemical formula for ammonium iodate is NH4IO3.
Probably manganese iodate: Mn(IO3)
The formula for manganese(II) iodate is Mn(IO3)2. The manganese ion is present in its +2 oxidation state, while iodate is a polyatomic ion with the formula IO3-.
manganese(II) iodate is Mn(IO3)2
The chemical formula for iron(II) hydride is FeH2.
Formula: NaIO3
