Question

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 completely fissioned plutonium-239 to the amount of energy released by the complete combustion of the same amount of coal.

Answer 1

Answer:hope this help

Step-by-step explanation:

Answer 2

The energy released by the complete fission of plutonium-239 is much greater than the energy released by the complete combustion of coal.

Nuclear fission, in which an atom's nucleus splits into two or more smaller nuclei and releases a significant amount of energy, occurs with plutonium-239.

When nuclear reactions occur, energy is usually released millions of times more than when chemical reactions, like burning coal, occur.

In contrast, when coal burns, carbon and oxygen undergo a chemical reaction that produces carbon dioxide and releases energy.
