A nuclear reaction is represented by the following equation:
`""_92^235U+_0^1n-> _56^139Ba+_36^94Kr+xc+E`
Name the process represented by this equation and describe what takes place

Make the correct choices in the following:
(a) In one atom of copper (mass number 63, atomic number 29) there are
What is the source of energy of sun or stars?
Assertion (A): In the process of nuclear fission, the amount of nuclear energy generated by the fission of an atom of uranium is so tremendous that it produces 10 million times the energy produced by the combustion of an atom of carbon from coal.
Reason (R): The nucleus of a heavy atom such as uranium, when bombarded with low energy neutrons, splits apart into lighter nuclei. The mass difference between the original nucleus and the product nuclei gets converted to tremendous energy.
