Question

One mole of N2H4 loses ten moles of electrons to form a new compound A. Assuming that all the nitrogen appears in the new compound, what is the oxidation state of nitrogen in A? (There is no change in the oxidation state of hydrogen.)




​

Answer 1

Explanation:

the oxidation state of hydrazine is-2. NH2-NH2. one mole of hydrazine contains 2moles of nitrogen and loses 10 moles of electrons.Hence 1 mole of N atom will loose 5 Moles of electrons.( no change in oxidation state of H). or 1 N atom will lose 5 electrons.Hence oxidation state of N increased by + 5.previous oxidation state was -2.New oxidation state would be -2+5= 3
