Question

part b
what is the basic difference between a nuclear fission reaction and a nuclear fusion reaction?
a fusion is a synthesis reaction while fission is a decomposition reaction.
b fusion is an exothermic reaction while fission is an endothermic reaction.
c fusion does not generate energy while fission generates a huge amount of energy.
d fusion only takes place in the stars so it cannot be used on earth to generate energy while fission can be used here for energy

Explanation:

Nuclear fusion combines small atomic nuclei into larger ones (synthesis), while nuclear fission splits large atomic nuclei into smaller ones (decomposition). Both are exothermic and generate energy; fusion research is ongoing for Earth use.

Answer:

A. Fusion is a synthesis reaction while fission is a decomposition reaction.
