Explanation:

In a nuclear reaction, according to Einstein's mass - energy equivalence formula \(E = mc^{2}\) (where \(m\) is the mass converted and \(c\) is the speed of light, \(c=3\times 10^{8}\ m/s\)). Since \(c\) is a very large number (\(c = 3\times10^{8}\ m/s\)), even a small amount of mass (\(m\)) conversion results in a large amount of energy (\(E\)) release. For example, in nuclear fission or fusion, a tiny fraction of the mass of nuclei is converted into energy, and this energy is enormous.

Answer:

a large amount of energy is released
