Chromium(III) oxide.
The chemical formula for the cation in the compound Cr(CO3)3 is Cr3 and for the anion is CO32-.
The answer from my chem class states its Cr(NO3)2
Cr(CN)3 is a molecular compound because it is composed of individual molecules held together by covalent bonds. It does not consist of ions like in ionic compounds.
+3 for Cr and -2 for O
The name of CrCN2 is chromium(II) cyanide.
The chemical formula for the cation in the compound Cr(CO3)3 is Cr3 and for the anion is CO32-.
Nonexistant. CrBr3 is a possibility.
Chromium nitrate

Compound????
(NH4)2O however this compound does not exist.
The name of CrCN2 is chromium(II) cyanide.
In CrBr (chromium monobromide) Cr would have an oxidation number of +1. This compound is not known perhaps you meant CrBr3, where chromium has an oxidation number of +3
The compound Cr(SO₃)₃ is called chromium(III) sulfite. It consists of chromium in the +3 oxidation state combined with three sulfite ions (SO₃²⁻). The Roman numeral III indicates the oxidation state of chromium in this compound.
CrNO3 ************2nd Opinion*********** To get the correct formula, you need to state the oxidation number of chromium in the compound, using a Roman numeral. It's likely to be chromium(III) nitrate, which is Cr(NO3)3
