It is the formula of Dichromate ion
Chromium has the chemical symbol Cr and an atomic number of 24 . Particulars can be found here: http://en.wikipedia.org/wiki/ChromiumWell, I have the same question respond please
CrO2this is the incorrect formula. For Chromium II oxide the formula is actually CrO without the 2. The reason for this is simple. the II after chromium indicates that it has a charge of +2, and the oxygen, we know is in group 16, has a charge of -2. The formula CrO2 is actually the formula for chromium IV oxide>
Chromium(II) nitrate: Cr(NO3)2Chromium(III) nitrate: Cr(NO3)3
The formula of chromium ion depends on its charge. For example, chromium in the +3 oxidation state forms the chromic ion (Cr3+), while chromium in the +6 oxidation state forms the chromate ion (CrO4^2-).
I'm not sure exactly what you're asking for.... ammonium nitrate is NH4NO3 and chromium by itself is Cr..... i hope this helped
The compound with the formula CaCr2O7 is called calcium dichromate.
Calcium dichromate
Cr(CN)2
Chromium (Cr) typically has a charge of +3 or +6 in ionic compounds.
The formula for Hexacarbonylchromium III ion is [Cr(CO)6]+3. It consists of a chromium ion with a charge of +3 surrounded by six carbon monoxide ligands.
+2
The charge on chromium in the complex Cr(NH)Br is 3.
Cr(SCN)3 is the chemical formula for the Chromium (III) Thiocyanate. This is because Chromium (III) has a charge of +3 while Thiocyanate has a charge of -1. To balance the charges, we switch the 2 charges. So we have 1 ion of chromium (III) with 3 ions of thiocyanate.
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
Oh, dude, you're hitting me with some chemistry vibes now? Alright, so the formula for manganese III chromate is Mn2(CrO4)3. Like, it's manganese with a +3 oxidation state bonding with chromate ions. It's like a chemical party in there, man.
The formula is CrBr2. This is derived by balancing the electrons from the atoms. Chromium II has a charge of +2 and Bromine has a charge of -1. Therefore in order for this molecule to be electrically balanced, there must be 2 bromine ions to offset the +2 charge of the chromium ion.
The chemical formula for chromic acetate is Cr(C2H3O2)3.
