Matter appears to be conserved in chemical reactions but not in nuclear reactions because:

the law of conservation of matter only applies to a limited number of chemical and nuclear reactions

the law of conservation of mass-energy applies only to nuclear reactions

in nuclear reactions, particles move too quickly to have their masses measured

in nuclear reactions the changes in mass are large enough to be detected

Verified Answer :

I think the best answer is B. Even this is the broadest case for the Conservation of matter and the one for Energy, the only way this can be applied is in nuclear rxns.

Answer:  The law of conservation of mass-energy applies only to nuclear reactions

Explanation:   In nuclear reactions, mass and energy both are conserved but not in a simple manner.

The nuclear reactions are known to violate the law of conservation of mass because the rest mass is converted and appears in the form of kinetic energy.

But the toral energy remains the same.

Thus it can be said that the sum of mass and energy are conserved n the nuclear reactions.
