C. Electrons are exchanged

Explanation:

Oxidation-Reduction reaction (Redox) is a type of chemical reaction in which there is a transfer of electrons between the reacting substance.

In this type of reaction, one of the reacting substance, called the Reducing  Agent, undergoes Oxidation (loss of electrons), while the other reacting substance, called the Oxidising Agent ,undergoes Reduction (gains electron).

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
