When the fission of uranium-235 is carried out about 0.1 percent of the mass of the reactants is lost during the reaction. What happens to this and ldquolost and rdquo mass?

The "lost" mass during the fission of uranium-235 is converted into energy according to Einstein's equation, (E=mc^2). This energy is released in the form of kinetic energy of the fission products, as well as radiation, heat, and neutrinos. This mass-energy conversion is a fundamental principle of nuclear reactions and is responsible for the immense energy produced in nuclear fission.
