Which statement best describes an oxidation-reduction reaction?

Question

A. a chemical reaction in which there are fewer products than reactants
B. a chemical reaction in which electrons are released from the system
C. a chemical reaction in which electrons are transferred between reactants
D. a chemical reaction that involves oxygen

Answer 1

C. a chemical reaction in which electrons are transferred between reactants

This statement best describes an oxidation-reduction (redox) reaction, as it involves the transfer of electrons, resulting in changes in the oxidation states of the participating substances.
