Answer 1

REDOX REACTION:

✷Redox is a chemical reaction in which the oxidation states of atoms are changed.

✷Any such reaction involves both a reduction process and a complementary oxidation process, two key concepts involved with electron transfer processes.

An oxidation-reduction (redox) reaction.
