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,
uranium238 is transformed in a series of nuclear reactions into
plutonium239. The plutonium239 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. [1]
83 Based on Table N, identify the decay mode of the
plutonium radioisotope produced in the breeder reactor. [1]
84 Compare the amount of energy released by 1 mole of completely
fissioned plutonium239 to the amount of energy released by the complete
combustion of 1 mole of methane. [1]
Answer>nuclear reactions are much
greater 
85 Write a notation for the nuclide represented by
missing product X in this equation. [1]
