Question

1. which of the following statements is true of a nuclear fission reaction? nuclear fission does not have commercial uses. nuclear fission takes place at very high temperatures only nuclear fission releases large amounts of energy as nuclei of atoms split apart. nuclear fission produces no radioactive waste. clear all

Explanation:

• Analyze the first option: Nuclear fission is used in nuclear power plants for electricity generation, so it has commercial uses. Eliminate this option.
• Analyze the second option: Nuclear fusion (not fission) requires very high temperatures. Fission can occur in controlled environments like reactors without extremely high temps. Eliminate this option.
• Analyze the third option: By definition, nuclear fission is the splitting of atomic nuclei, and this process releases a large amount of energy (used in power plants, etc.). This statement is correct.
• Analyze the fourth option: Nuclear fission produces radioactive waste (e.g., spent fuel rods), so this is false. Eliminate this option.

Answer:

The correct statement is: Nuclear fission releases large amounts of energy as nuclei of atoms split apart. (The option with this text)
