O=-2
O5=-10
As2+(-10)=0
As2-10=0
As2=10
As=10/2
As=5
-2 for each O
+5 for each As
As2O5
Each Br atom has an oxidation number of zero.
No. The oxidation numbers of nitrogen and oxygen do not change.
C2O5 Just look at the latin roots (di, pent >> 2, 5)
In chemistry, the oxidation state is a number assigned to an element as an indicator of the degree of oxidation of an atom in a chemical compound."The charge an element would have if it were an ion "Oxidation state is the same as the oxidation number. It is an indicator of the degree of oxidation of an atom in a chemical compound.
Yes
