Base your answers
to questions 82 through 85 on the information below.
A breeder reactor is one type of nuclear reactor. In a breeder reactor,
uranium-238 is transformed in a series of nuclear reactions into
plutonium-239. The plutonium-239 can undergo fission as shown in the
equation below. The X represents a missing product in the equation.
82 Determine the number of neutrons in an atom of the
uranium isotope used in the breeder reactor. 
83 Based on Table N, identify the decay mode of the
plutonium radioisotope produced in the breeder reactor. 
84 Compare the amount of energy released by 1 mole of completely
fissioned plutonium-239 to the amount of energy released by the complete
combustion of 1 mole of methane. 
|Answer-->nuclear reactions are much
85 Write a notation for the nuclide represented by
missing product X in this equation.
