Reference: OCR
The large value of c² means even a tiny mass defect corresponds to a very large energy release, which is why nuclear reactions release far more energy per kilogram than chemical reactions.
Energy is released when the average binding energy per nucleon increases from reactants to products, because the total mass decreases.
