Question

1. list three positive uses of nuclear chemistry. 20. identify the following as fission or fusion. 24. list properties of fusion and fission.

Explanation:

Step1: Recall nuclear chemistry uses

Medical imaging (PET - scans), power generation, cancer treatment (radiation therapy).

Step2: Identify fusion/fission

Left: Deuterium and tritium combine to form helium - fusion. Right: Neutron splits nucleus - fission.

Step3: List properties

Fusion: High temp, light nuclei combine. Fission: Heavy nucleus splits, releases neutrons.

Answer:

1. Medical imaging, power generation, cancer treatment
2. Left: Fusion; Right: Fission
3. Fusion: Light nuclei combine, high temp. Fission: Heavy nucleus splits, releases neutrons
