Annon:The chemical formula of chromium II sulfate is CrSO4.
Miki-San-X: Actually
Since this is probably Ionic naming since it starts with a metal and ends with a non metal you would take chromium (II) Sulfate and cross them-
Like so-
Start:
Cr(II) SO4 (-2)
We know that sulfate is SO4 with a -2 superscript and that chromium is a transition metal, but that it has a positive charge to counteract the negative charge of the -2.
You will drop the charge and cross them-
Cr2(SO4)2
since you brought the -2 from the sulfate down to the chromium it becomes positive 2 because you dropped the charge before crossing. The reason you put the (SO4) in parenthesis is because you cannot, in a problem like this, have 42 next to your polyatomic ion. You have TWO of that ion, NOT 42.
Hope I helped <3
AZ: The chemical formula of chromium (II) sulfate is actually CrSO4 because chromium (II) has a charge of +2 and sulfate has a charge of -2.
There is no need to have two chromium ions and two sulfate ions like in the formula Cr2(SO4)2 because the charges already cancel each other out. You only need one of each ion.
The (II) in chromium (II) represents its charge, not how many ions there are in the formula.
Miki-San-X's formula Cr2(SO4)2 is technically correct, but it's not as accurate as the formula CrSO4 because you would have to simplify it, therefore if you were asked this question on a test, CrSO4 would be the right answer.
