In this case you have a Salt that comes from a binarius acid (HCl) you have to remember in salts you are always using the oxidation number with H (Cl= -1) so Cr is using 3 :) as you have seen im not a English native speaker... sorry for mistakes :D

What is the name of the ionic compound CrCl3?
Chromium (III) chloride
Which element undergoes Oxidation in k2cro4 na2so3 hcl-kcl na2so4 crcl3 h2o?
S sulfur
What does chromium react to?
Under still milder conditions, chromium metal reacts with the halogens fluorine, F2, chlorine, Cl2, bromine, Br2, and iodine, I2, to form the corresponding trihalideschromium(III) fluoride, CrF3, chromium(III) chloride, CrCl3, chromium(III) bromide, CrBr3, or chromium(III) iodide, CrI3.
Formula for chromium III Chloride?
(NH3)5Cl3CrIt would be more descriptive to write it like this though [(NH3)5ClCr]2+ 2Cl-
What is the chemical formula for chromite?
Commercially anhydrous chromium(III) chloride may be prepared bychlorination of chromium metal directly, or indirectly by chlorination ofchromium(III) oxide in the presence of carbon at 650--800 °C, with carbon monoxide as a side-product:[3] Cr2O3 + 3 C + 3 Cl2 → 2 CrCl3 + 3 CO It may also be prepared by treating the hexahydrate with thionyl chloride:[4] CrCl3·6H2O + 6 SOCl2 → CrCl3 + 6 SO2 + 12 HCl
What is the formula for chromium3 chloride?
CrCl3: A chloride ion has only a single negative charge; therefore, three of them are required to have the same magnitude of electric charge as a chromium (III) ion.
Why do I use the Roman numeral III for CrCl3?
Because the chromium ion is in its trivalent form.
What is the name of the ionic compound CrCl3?
Chromium (III) chloride
What is the correct formula for the ionic compound formed between chromium and chloride?
Chromium (II) chloride = CrCl2Chromium (III) chloride = CrCl3 Chromium (IV) chloride = CrCl4
Which element undergoes Oxidation in k2cro4 na2so3 hcl-kcl na2so4 crcl3 h2o?
S sulfur
What is the formula for chromium III bromide hexahydrate?
Chromium has four oxidation states: 2, 3, 4, and 6. Chlorine has one, and it's -1. There will be a chloride for each oxidation state of chromium. Here they are: CrCl2 Chromium (II) chloride CrCl3 Chromium (III) chloride CrCl4 Chromium (IV) chloride CrCl6 Chromium (VI) chloride

What is chemical formula of CrCI3?
There is no compound with the formula CrCI3 (uppercase i). You most likelt mean CrCl3, with a lowercase L. This is chromium III chloride.

How many grams of chromium (III) chloride are required to produce 75.0 g of silver chloride?
The formula of chromium chloride is CrCl3 and the formula for silver chloride is AgCl. The relevant formula unit masses are 158.36 for chromium (III) chloride and 143.32 for silver chloride. The gram atomic masses of chlorine, chromium, and silver are 35.453, 51.996, and 107.866 respectively. Therefore, the mass fraction of chloride in chromium (III) chloride is [3(35.453)/158.36] or 0.671628 and the mass fraction of chloride in silver chloride is 35.453/143.32 or 0.24737. Therefore, to form 75.0 g of silver chloride, (0.24737)(75.0) or 18.55 g of chloride is needed, and this amount of chloride is contained in 18.55/0.6716 or 27.6 g of chromium (III) chloride, to the justified number of significant digits.
