Work this out like this Chroium you are told is oxidation state +3. Selenium is in group 16 along with oxygen and sulfur so it will have a preferred oxidation state of -2. Then balance it, oxidation staes can be treated like ionic charges:-

Chromium nitrate chemical formula?
Chromium(III) nitrate is Cr(NO3)3
What is the name for the compound CaCrO4?
That would be chromium(II) sulfate, but really, chromium mostly exists as Cr(III) or Cr(VI), which would change the formula.
What is the product formula of chromium III acetate and tin?
There would be no reaction because tin will not replace the chromium in the chromium (III) acetate. Refer to the related link for an activity series for metals.
What is the balanced formula for CrN2?
The formula is CrN. It is called Chromium nitride and Chromium(III) nitride. Chromium also forms second interstitial nitride, dichromium nitride - Cr2N
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
What is the chemical formula of iron iii and selenium?
The chemical formula of iron(III) and selenium is Fe2Se3 - iron(III) selenide.
What is chemical formula for chromium arsenate?
The chemical formula of chromium(III) arsenate is CrAsO4.
What is the chemical formula for chromium phosphide?
The chemical formula for chromium phosphide is CrP.
What is the formula for chromium (III) fluoride?
the chemical formula for chromim(II) fluoride is CrF2
What is the chemical formula for chromium (111) sulfate?
The chemical formula for chromium (III) sulfate is Cr2(SO4)3.
What is the chemical formula for chromium (III) iodide?
The chemical formula for chromium(III) iodide is CrI3.
Chromium nitrate chemical formula?
Chromium(III) nitrate is Cr(NO3)3
Chemical formula for the compound formed between chromium III and borate?
The chemical formula for the compound formed between chromium III and borate is Cr(B(OH)4)3.
What is the Chemical formula for chromium III carbonate yields chromium III oxide plus carbon dioxide?
The chemical formula for chromium III carbonate is Cr2(CO3)3. When it decomposes, it yields chromium III oxide (Cr2O3) and carbon dioxide (CO2).
The name for the compound with the formula Cr2O3 would be written as what?
The compound with the formula Cr2O3 is called chromium(III) oxide.
What is the name for the compound CaCrO4?
That would be chromium(II) sulfate, but really, chromium mostly exists as Cr(III) or Cr(VI), which would change the formula.
What is the formula for chromium iii thiocyanate?
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.
