Cumulus · Answer 1

6 moles of electrons

Explanation:

Let us consider the species NO3 - and ClO-. The NO3 - is oxidized to NO the oxidation number of nitrogen is decreased from + 5 to + 2.

The oxidation number of chlorine is increased from + 1 to + 3. This implies that six electrons were transferred in the balanced reaction equation shown in the question. Hence the answer.
