Question

The charge of a vanadium ion in the compound V2O5 is:
A.10-
B.2+
C.5+
D.10+
E.none of the above

Answer 1

ok, so we know that O almost always has a (-2) charge.. On V2O5 you have 5 oxygen, the over all charge on V2O5 is neutral. What must be the charge on V if you have 2 of them?

Answer 2

You could also do this algebraically if you wish => 2(x)+5(-2)=0 solve for x

Answer 3

I believe it is +5

Answer 4

Yep!

Answer 5
