Answer:

C. copper.

Explanation:

  • The atom which loses electrons (its oxidation sate be more positive) is the atom that is oxidized.
  • While, the atom which gains electrons (its oxidation sate be more negative) is the atom that is reduced.

  • Nitrogen:

It is oxidation sate is changed from (+5) in the reactants (NO₃⁻) to (+4) in the products (NO₂). N gains 1 electron

So, it is reduced.

  • Oxygen:

It is oxidation sate is the same (-2) in the reactants (NO₃⁻) and (-2) in the products (NO₂).

So, it is neither be oxidized nor reduced.

  • Copper:

It is oxidation sate is changed (0) in the reactants (Cu) to (+2) in the products (Cu²⁺). Cu loses 2 electrons.

So, it is oxidized.

  • Hydrogen:

It is oxidation sate is the same (+1) in the reactants (H⁺) and (+1) in the products (H₂O).

So, it is neither be oxidized nor reduced.
