The characteristics of two different types of reactions are shown below:
reaction a: an atom loses electrons during the reaction.
reaction b: an atom loses protons and neutrons during the reaction.

which statement is true about the two reactions?

both reactions retain the identity of the elements.

both reactions change the identity of the elements.

reaction a produces more energy than reaction b.

reaction b produces more energy than reaction a.

Option (d) is the correct answer.

Explanation:

A chemical reaction is defined as the reaction in which there is formation of new compound due to exchange of electrons between the combining atoms.

For example, .

Whereas a nuclear reaction is defined as the reaction in which splitting or combining of atomic nuclei takes place.

For example,

Since, atomic nuclei are involved in nuclear reactions. Hence, they tend to release more energy.

Therefore, we can conclude that the statement reaction B produces more energy than Reaction A, is true about the two reactions.
