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.
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.
It is oxidation sate is the same (-2) in the reactants (NO₃⁻) and (-2) in the products (NO₂).
<em>So, it is neither be oxidized nor reduced.</em>
<em></em>
It is oxidation sate is changed (0) in the reactants (Cu) to (+2) in the products (Cu²⁺). Cu loses 2 electrons.
<em>So, it is oxidized.</em>
<em></em>
It is oxidation sate is the same (+1) in the reactants (H⁺) and (+1) in the products (H₂O).
<em>So, it is neither be oxidized nor reduced.</em>
