Question

Which explains why more energy is released in nuclear reactions than in chemical reactions? (2 points). A.Chemical reactions are always endothermic.. B.No molecular bonds are broken in nuclear reactions.. C.Protons and neutrons are exchanged in chemical reactions.. D.In nuclear reactions, mass is converted to energy..

Answer 1

Answer: Option (D) is the correct answer.

Step-by-step explanation:

In a nuclear reaction, nucleus of atom(s) is involved in the reaction whereas in a chemical reaction electrons are involved in the reaction.

Therefore, in a nuclear reaction there occurs change in mass of the atoms participating in the reaction and the products formed. This change in mass is known as mass defect.

This difference in mass is released as energy.

Hence, we can conclude that in nuclear reactions, mass is converted to energy.

Answer 2

"In nuclear reactions, mass is converted to energy" is the statement that explains why more energy is released in nuclear reactions than in chemical reactions. The correct option among all the options that are given in the question is the last option or option "D". I hope the answer has come to your help.
