Answer 1

Answer:

Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.

Answer 2

Answer:

Nuclear reactor is the machine that is used to form nuclear chain reactions and also to control nuclear chain reactions.

Explanation:

Nuclear chain reactions are conducted in nuclear reactor which is also called as atomic pile.

Nuclear fission reaction is the nuclear chain reaction where decay of the nucleus of radioactive elements takes place.

Nuclear fusion reaction is the nuclear chain reaction where the nucleus get combined in a radioactive element.
