Iron(III)Oxide
Nickel oxide is Ni(III)2O3, which does balance.
By rusting hydrated iron(III) oxide is formed.
No, manganese III dichromate is a solid compound and not typically soluble in water.
Gold(III) chloride, traditionally called auric chloride, is a chemical compound
That would be the bichromate or sometimes called the dichromate ion. Example: Sodium bichromate (or sodium dichromate) is Na2Cr2O7.
The chemical formula for gold (III) arsenide is AuAs. In this compound, gold is in the +3 oxidation state, denoted by the Roman numeral III in parentheses. Arsenic is in the -3 oxidation state, so one gold atom combines with one arsenic atom to form a stable compound with a 1:1 ratio.
It's name is "barium dichromate". Some people also use the antiquated (and wrong) term "bichromate", which should no longer be used. (See also the provided link.)
If it existed it would be gold(II) oxide. The stable gold oxide is gold(III) oxide Au2O3
Gold (III) bromide has the chemical formula AuBr3. It usually exists as a dimer with the formula Au2Br6. Gold (III) bromide may be used as a catalyst for Diels-Alder reactions.
It is Ferrous chromate or Iron (II) chromate .
