What can be said about nuclear fusion reactions of the following systems I) (5)B I) ()C ()N As the charges of identical small nuclei increase, the energy required to initiate nuclear fusion of them O System (1) requires more energy to initiate fusion O System (II) requires less energy to initiate fusion O System (II) requires more energy to initiate fusion O System'(III) requires more energy to initiate fusion O System (III) requires less energy to initiate fusion

A nuclear power station delivers 1 GW of electricity for a year from uranium fission. Giventhat a single fission event delivers about 200 MeV of heat, estimate the number of atomsthat underwent fission, their mass, and the loss of mass of the fuel elements.

Nuclear fission and nuclear fusion each release enormous amounts of energy as a result of changes in the nuclei of atoms. Distinguish be- tween fission and fusion by comparing the process, the starting mate- rial, and the location where each commonly occurs. Answer in complete sentences.
