Question

What is the oxidation number of oxygen in Fe₂O ?​

Answer 1

Answer:

2

(The oxidation state of fluorine in F2 is zero.) Oxygen has an oxidation state of -2 in most of its compounds.

Answer 2

ANSWER:

Peroxides include hydrogen peroxide, H2O2. This is an electrically neutral compound and so the sum of the oxidation states of the hydrogen and oxygen must be zero. Since each hydrogen has an oxidation state of +1, each oxygen must have an oxidation state of -1 to balance it.
