Question

question 13 (multiple choice worth 3 points) oss.03the model below represents a nuclear reaction. atom 1 is present before the reaction and atom 2 and atom 3 are produced after the reaction. atom 1 = atom 2 + atom 3 + energy the model most likely represents a reaction which

• produces energy in nuclear power plants
• takes place when atoms become inactive
• takes place when atoms combine
• would not produce energy in nuclear power plants

Explanation:

1. Analyze the reaction model: The model shows one atom (Atom 1) splitting into two atoms (Atom 2, Atom 3) and releasing energy, which is nuclear fission.
2. Evaluate each option:

• Option 1: Nuclear power plants use nuclear fission (splitting of atoms) to produce energy, so this matches the reaction model.
• Option 2: The reaction is about splitting, not atoms becoming inactive (decay is different, and this model is fission).
• Option 3: Atoms combining is fusion, not fission (the model is splitting, not combining).
• Option 4: Nuclear power plants do use fission (this reaction) to produce energy, so this is incorrect.

Answer:

A. produces energy in nuclear power plants
