Revolt · Accepted Answer

energy; heavier atoms; a neutron

Question 2

Complete this equation that represents the process of nuclear fission. A: B:

Revolt · Accepted Answer

Part 1: 146; Part 2: 56

Question 3

Complete this equation that represents the process of nuclear fusion. A: B:

Revolt · Accepted Answer

Part 1: 222; Part 2: 86

Question 4

Explain why nuclear fission and nuclear fusion release large amounts of energy.

Revolt · Accepted Answer

In nuclear fission, the mass of the original nucleus is greater than the mass of the products. The extra mass is converted to energy. In nuclear fusion, the total binding energy of the lighter nuclei is greater than the binding energy of the heavier nucleus. Extra energy is released during the reaction.

Question 5

What is the energy equivalent of an object with a mass of 1.83 kg?

Revolt · Accepted Answer

1.65 × 1017 J

Question 6

A power plant needs to slow down the fission reactions in its nuclear reactor. In which direction should the uranium-containing rods in the diagram be moved?

Revolt · Accepted Answer

down

Question 7

Why is nuclear energy able to be used for practical purposes?

Revolt · Accepted Answer

The reactions are controlled to regulate energy output.

Question 8

What did you include in your response? Check all that apply.

Revolt · Accepted Answer

In nuclear fission, the mass of the original nucleus is greater than the mass of the products.; In nuclear fission, the extra mass is converted into energy.; In nuclear fusion, the total binding energy of the lighter nuclei is greater than the binding energy of the heavier nucleus.; Extra energy from nuclear fusion is released.
