When the oxidation-reduction reaction shown here is balanced using the smallest whole-number coefficients, how many electrons are transferred?
Cu²⁺(aq) + Al(s) $\rightarrow$ Cu(s) + Al³⁺(aq)

Question

When the oxidation-reduction reaction shown here is balanced using the smallest whole-number coefficients, how many electrons are transferred? Cu²⁺(aq) + Al(s) $\rightarrow$ Cu(s)+ Al³⁺(aq)

Quizplus · Accepted Answer

In the balanced reaction, 2 moles of Al each lose 3 electrons (total 6 electrons), and 3 moles of Cu²⁺ each gain 2 electrons (total 6 electrons), so 6 electrons are transferred.
