Question

What does Einstein's famous equation for nuclear energy, E = mc2, mean?

Some mass and energy are lost in a nuclear reaction.

Mass and energy are destroyed in a nuclear reaction.

Some mass is converted into energy in a nuclear reaction.

Mass and energy are produced in a nuclear reaction.

Answer 1

Some mass is converted into energy in a nuclear reaction. Hope this helps!

Answer 2

Answer;

Some mass is converted into energy in a nuclear reaction.

Step-by-step explanation;

• Nuclear fission and nuclear fusion are the two types of nuclear reactions. Nuclear fusion involves the combining of two small nuclei to form a larger nuclei coupled with the release of energy. Nuclear fission on the other hand involves the splitting of a heavy larger nuclei to yield smaller nuclei and is also coupled with the release of energy.
• In both nuclear fission and nuclear fusion reactions, energy is converted to mass.
• In nuclear fission, the resultant products have a slightly smaller nuclear mass as compared to heavy nucleus. This difference in mass is because some mass is converted to energy during the fission.
• Similarly in nuclear fusion some of the mass of the initial nuclei is converted into energy in the form of heat or light.
