Answer:
A nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass.
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.
Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.
A chemical reaction can be defined as a reaction in which two or more atoms of a chemical element react to form a chemical compound.
On the other hand, a nuclear reaction can be defined as a reaction in which the nucleus of an atom is transformed by being joined (fusion) or split (fission) with the nucleus of another atom of a radioactive element.
The energy that holds the neutrons and protons found in the nucleus of an atom together is known as Nuclear energy. It is also stored in the nucleus of an atom as potential energy.
Hence, the statement which illustrates the difference between a chemical reaction and a nuclear reaction is that, a nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass.
The law of conservation of mass states that the mass of a substance in an isolated system can neither be created nor destroyed by a chemical reaction.
