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.

Reaction B produces more energy than Reaction A.

Explanation:

From the description of A, we know it is a chemical reaction. In chemical reactions, an atom loses electrons in the process of oxidation. The nucleus which contains the protons and neutrons are not involved in the reaction.

In nuclear reactions,B, changes occur within the atomic nucleus.

Both nuclear and chemical reactions are accompanied by release or absorption of energy. But nuclear reactions produce far greater energy compared to chemical reactions.

Reaction B produces more energy than Reaction A.

I hope this helps! I really don't know how to explain it, but I knew the answer! :)
