I would say d. hope this helps.
I easily finished my homework
The statement that illustrates the difference between a chemical reaction and a nuclear reaction is a nuclear reaction releases less energy per gram but does not appear to violate the law of conservation of mass. So, option D is correct.
<h3>What is a Nuclear reaction?</h3>
A nuclear reaction may be described as a procedure in which the nucleus of an atom is transformed by being diverged apart or united with the nucleus of another atom.
During the process of nuclear reaction, huge energy will be released throughout the process. It is an uncontrolled reaction that emits high energy.
It follows the principles of the law of conservation of mass because the mass numbers of the reactants earlier than the reaction equal the sum of the mass numbers of the interests after the reaction.
Therefore, the correct option for this question is D.
