The statement that is not correct is E. As written above, four electrons are transferred from nitrogen to oxygen, not from oxygen to nitrogen, in this reaction. Therefore, statement E should be corrected as follows: As written above, four electrons are transferred from nitrate to nitrogen in this reaction. The other statements are correct. Nitrate is the oxidizing agent because it causes nitrogen to be reduced and oxygen to be oxidized. Oxygen is oxidized because it loses electrons and nitrogen is reduced because it gains electrons. Water can be written as a reactant in the oxidation half reaction because it is formed when oxygen gains electrons.
