True False
Energy is created from moving electrons in oxidation.


Oxidation and reduction are separate and do not rely on each other both create energy.


Energy can neither be created nor destroyed it can only change forms.


Oxidation and reduction reactions are paired. Electrons move to a state of lower potential energy for storage by being drawn to the atom with the highest electronegativity.

1. Energy is created from moving electrons in oxidation. — False
Reason: Oxidation can release energy (or convert it), but it does not create energy — energy is conserved.

2. Oxidation and reduction are separate and do not rely on each other; both create energy. — False
Reason: Oxidation and reduction are coupled (redox); electrons lost by one species are gained by another, and neither “creates” energy.

3. Energy can neither be created nor destroyed; it can only change forms. — True
Reason: This is the law of conservation of energy.

4. Oxidation and reduction reactions are paired. Electrons move to a state of lower potential energy for storage by being drawn to the atom with the highest electronegativity. — True
Reason: Redox reactions are paired, and electrons tend to move toward more electronegative atoms (lower potential energy), where their energy is effectively stored.
