Ответ:
The correct answer is D). See the explanation below, please.
Explanation:
Option D corresponds to the nuclear fission between Deuterium and Titrio, throwing Helium as products and with the emission of a neutron.
Ответ:
2H + 3H → 4He + 1n is an example of nuclear fission
Explanation :
Nuclear fission is a process in which two smaller nuclei are formed because of the splitting of a large nucleus. The process of nuclear fission occurs when a nucleus absorbs the neutron that produced because of radioactivity decay of another atom.
In the equation 2H + 3H → 4He + 1n, there is nuclear fission between Titrio and Deuterium. Helium is thrown as products with the emission of neutrons. This reaction gives an energy of about 17.6 MeV .
About 80 percentage of energy from this reaction is released in the form of neutron.
