Question

During a nuclear reaction, mass is lost. This results in:
A. A release of energy
B. An increase in the speed of light
C. A gain of energy
D. A decrease in the speed of light
E. No change in light

Answer 1

In nuclear science, a nuclear reaction is a cycle wherein two nuclei or nuclear particles bombard together, to create unexpected products in comparison to the initial particles. On a basic level a reaction can include multiple particles bombarding, however such a function is outstandingly rare.

Complete answer:
An atomic nucleus consists of protons and neutrons bound together. The mass of any core other than Hydrogen isn't equivalent to the whole of the majority of the individual protons and neutrons.
At the point when two lighter nuclei are melded to make a heavier nuclei, the resulting nuclei is less big than the aggregate of the two original nuclei. The mass contrast is changed over into energy which is the reason combination response discharge energy.
Any nucleus of Iron or heavier components require more energy to break to make heavier components. In this way, the mass of the nucleus is heavier than the entirety of the masses of the component protons and neutrons. Energy should be changed over into mass to make heavier components. This occurs in supernova blasts where nuclei are assaulted with high energy neutrons.
Bombarding certain substantial isotopes, for example, Uranium-235, with neutrons makes the nucleus split into two. It can likewise release neutrons. In such fission reactions the aggregate of the masses of the reaction products is not exactly the mass of the first nucleus. This mass difference is changed over into energy which is the reason why fission reactions release energy. During an atomic reaction, mass is lost. This outcomes in the release of energy. The lost mass is changed over into energy. The energy delivered is gotten by Einstein's equation.

**Hence, the correct option is A. A release of energy

Note: **
Einstein's equation enables researchers to comprehend what occurs in atomic reactions and why they produce so much energy. At the point when the nucleus of a radioisotope goes through splitting or combination in an atomic reaction, it loses a little measure of mass.
