Cr+3 C2H3O2-1 <----- these are the ions and their charges
Cr+3 C2H3O2-1 C2H3O2-1 C2H3O2-1 <---- the charges have to add up to zero, so three -1 acetate ions cancel out one +3 chromium ion
Cr(C2H3O2)3 <----- simplify

One version of this formula is Cr(C2H2O2)3.
Formula: (CH3COO)3Cr
chromium 3= Cr*3+
Cr(CH3COO)3
Cr(CH3COO)2
The chemical formula for chromium (III) sulfate is Cr2(SO4)3.
Chromium (II) Carbonate. Although I'm not sure Chromium (II) can form, there might be an overall charge on your formula there...
Formula: Ga(BrO3)3
Chromium(III) borate has the chemical formula CrBO3.
Chromic acid is the acid in chromic acid. The chemical formula is H2CrO3 (Not correct)Added & Corrected:Often the species are assigned the formulas H2CrO4 (dihydrogen chromate) and H2Cr2O7 (dihydrogen dichromate).The anhydride of these "chromic acids" is chromium trioxide, also called chromium(VI) oxide (2CrO3=Cr2O6).Regardless of its exact formula, chromic acid features chromium in an oxidation state of +6 (or VI), the highest known.

Chromium(III) nitrate is Cr(NO3)3
The chemical formula of chromium nitrate is Cr(NO3)3.
Formula: Ga(BrO3)3
Chromium(III) borate has the chemical formula CrBO3.

The answer from my chem class states its Cr(NO3)2
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
Silver dichromate has the molecular formula of Ag2Cr2O7. Ag corresponds to silver, Cr to chromium, and O is oxygen. The atomic mass of silver dichromate is 431.8 grams per mole (using 4 significant digits).
Cr(NO3)3 (aq) + Na3PO4 (aq) --> CrPO4 (s) + 3NaNO3 (aq)
Chromium has four oxidation states: 2, 3, 4, and 6.Iodine has one, and it's -1.There will be a iodide for each oxidation state of chromium.CrI2 Chromium (II) iodideCrI3 Chromium (III) iodideCrI4 Chromium (IV) iodideCrI6 Chromium (VI) iodide
