What is the oxidation number of chromium for CrBr2?
The oxidation number of chromium in CrBr2 is +2. This is because bromine typically has an oxidation number of -1 and there are two bromine atoms in CrBr2, leading to a total oxidation number of -2. The oxidation number of chromium must therefore be +2 to balance the charges.
What is the formula for chromium 2 bromide?
Some metals can have multiple different charges, so a number after the name is given to tell what charge it has. Whereas Bromide on the other hand always has the same change (-1.) In this case you have a Chromium with a 2+ charge, and would then need 2 Bromide ions to make the compound neutral. Thus the formula is CrBr2.
Compound name for chromium bromide?
Another chemical name is chromium trichloride or chromic chloride. Chromium(III) chloride is a chemical name as well.
Write the reaction when chromium bromide is put into water?
When chromium bromide is put into water, it dissociates into ions. The reaction is: CrBr2(s) → Cr2+(aq) + 2Br-(aq).
What is the chemical formula for chromium II borate?
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.

What is the chemical equation for chromium III chlorate ion?
Any balanced equation for a chemical element; the chemical symbol of chromium is Cr.
Chromium forms two bromides one that is 17.82percent chromium by mass and another that is 24.55 percent chromium. In the first sample the mass of chromium per 1 gram of bromide?
Chromium form three (not only two) bromides: * CrBr2, containing 24,759 85 % chromium * CrBr3, containing 17,991 45 % chromium * CrBr4, containing 14,129 09 % chromium 1 gram of CrBr3 contain 179,91 45 mg chromium.
