What type of nuclear reaction is shown in the diagram below? write 2 - 3 sentences describing what happens in this reaction, where it happens, and how the energy released can be harnessed for use in homes.

Here we can see in the given picture that a small particle is incident upon a big nuclei

Then a big nuclei is broken into two smaller nuclei

This type of reaction in which a unstable big nuclei is converted into small size stable nuclei is known as Nuclear Fission Reaction

here to start such type of nuclear fission reaction we require initial energy which is here given by high kinetic energy neutrons

so here if neutrons of sufficient kinetic energy are projected towards unstable big nuclei then these big unstable nuclei will convert into stable small nuclei

In this whole reaction the mass of stable nuclei formed is less than the total mass of initial nuclei present

So here due to mass difference energy is released which is given by Einstein's Equation

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
