Assign oxidation states help!

What are the oxidation states of the atoms in

Cr(C2H3O2)2
C=?
H=?
Cr=?
O=?

Thanks!

First of all,

O.N of Cr here is +2

O.N of O is always= -2

Carbon(C) in acetate ion is neutral so it's oxidation number will be 0

O.N of H is always +1

In this (chromium (||) acetate),

we have= +2(Cr) +0(C) +6(+1)(H) +4(-2)(O)=0
