Base your answers to questions 14 on the information below and on your knowledge of chemistry.

Nuclear fission is currently used to produce electricity in a nuclear power plant. One possible fission reaction is represented by the equation below.

The barium-141 decays by beta emission and has a half-life of 18.3 minutes.

Compare the amount of energy released by the fission of one mole of uranium-235 to the amount of energy released by the combustion of one mole of octane fuel, C_{8}H_{18}. [1]*

Base your answers to questions 15 on the information below and on your knowledge of chemistry.

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.

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.*
