Question

Quizplus · Accepted Answer

In an oxidation-reduction reaction, electrons are transferred from one species to another. Fe (iron) loses two electrons and becomes Fe2+, and Cu (copper) gains two electrons and becomes Cu+. Therefore, iron transfers two electrons to copper, making choice C the correct answer.
