Formula: AsI3
As-3
As I3
FeAs2
Fe3As2
I think you mean As2Ba3. That would be Barium Arsenide.
FeAs2 is the most common arsenide (míneral lollingite) it is not ionic. There are arsenide phases FeAs and Fe3As2 corresponding to iron(III) arsenide and iron (II) arsenide, again the bonding is not ionic.
The formula for Iron(II) sulfate is FeSO4.
The formula for manganese(VII) arsenide is Mn3As7.
Iron(II) Phosphide = Fe3P2 Iron(III) Phosphide = FeP
I think you mean As2Ba3. That would be Barium Arsenide.
FeAs2 is the most common arsenide (míneral lollingite) it is not ionic. There are arsenide phases FeAs and Fe3As2 corresponding to iron(III) arsenide and iron (II) arsenide, again the bonding is not ionic.
Iron (III) Arsenide
The chemical formula for copper (III) arsenide is Cu3As.
The formula for Iron(II) sulfate is FeSO4.
Iron (II) hydride has the formula FeH2.
The chemical formula for the compound Strontium arsenide is SR3AS2.
An arsenopyrite is a silvery-grey ore of arsenic - a mixed arsenide and sulphide of iron, chemical formula FeAsS.
Formula of 3 types of Iron oxides: Iron(II) oxide= FeO Iron(III) oxide= Fe2O3 Iron(II,III) oxide= Fe3O4
The chemical formula of iron(II) phosphate is Fe3(PO4)2.
The chemical formula of iron(II) phosphate is Fe3(PO4)2.
The formula for iron(II) flluoride is FeF2. The formula for iron (III) fluroide is FeF3.
