The nuclear reaction that releases the most energy per kilogram is:

Question

Quizplus · Accepted Answer

Hydrogen fusing to helium in the process of nuclear fusion releases the most energy per kilogram. This is because it follows Einstein's famous equation E=mc², where the mass defect (the difference between the mass of the initial hydrogen and the mass of the resulting helium) is converted into energy. This is the process that powers the sun and other stars in the universe. The other options, such as oxygen fusing to silicon or carbon fusing to magnesium, also release energy in nuclear reactions, but not as much as hydrogen fusing to helium.
