List TWO things that can occur during a reduction reaction.

Final answer: During a reduction reaction, two things can occur: the gain of electrons and the decrease in oxidation state. Explanation: In a reduction reaction, two things can occur: The gain of electrons: Reduction involves the gain of electrons by an atom, ion, or molecule. For example, when a metal ion gains electrons and forms a neutral metal atom, it is undergoing reduction. The decrease in oxidation state: Reduction also involves the decrease in the oxidation state of an element. This means that the element has gained more negatively charged particles or has lost positively charged particles. Learn more about Reduction reaction here: brainly.com/question/19528268
