Final answer:
The commonly used units of energy are electron volts (eV) and kilocalories per mole (kcal/mol).
Step-by-step explanation:
The commonly used units of energy are:
- Electron volts (eV): The electron volt is often used for submicroscopic processes.
- Kilocalories per mole (kcal/mol): Kilocalories per mole is used to measure energy in chemistry.
- Newtons (N): Newtons are not commonly used as units of energy.
- Meters per second (m/s): Meters per second are not commonly used as units of energy.
So, the correct answer is B) Electron volts, Kilocalories per mole.
