Question

5 multiple choice 2 points given the diagram representing a reaction: which type of change is represented? fission fusion deposition evaporation

Explanation:

Step1: Recall definitions

Fission: A heavy nucleus splits into lighter nuclei.
Fusion: Light nuclei combine into a heavier nucleus.
Deposition: Gas to solid phase change.
Evaporation: Liquid to gas phase change.

Step2: Analyze the diagram

The diagram shows \(^{235}_{92}\text{U}\) (a heavy nucleus) splitting into \(^{94}_{38}\text{Sr}\) and \(^{140}_{54}\text{Xe}\) (lighter nuclei) with neutrons released. This matches the definition of fission.

Answer:

fission
