Question

which statement illustrates the difference between a chemical reaction and a nuclear reaction? a nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass. a nuclear reaction releases less energy per gram and appears to violate the law of conservation of mass. a nuclear reaction releases more energy per gram but does not appear to violate the law of conservation of mass. a nuclear reaction releases less energy per gram but does not appear to violate the law of conservation of mass.

Answer 1

The Correct answer is option D, nuclear reaction releases less energy per gram but does not appear to violate the law of conservation of mass.

Reason -

Tremendous amount of energy is released in a nuclear reaction as compared to a chemical reaction and this is so because a nuclear reaction involves changes in the nucleus of an atom while in a chemical reaction there is only rearrangement of electrons. Also the nuclear reactions are continuous and occur in a chain that releases high energy. They follow law of conservation of mass as the mass numbers of the reactants before the reaction equals the sum of the mass numbers of the products after the reaction.

Answer 2

The answer is  a nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass.

Some main differences between the chemical and nuclear reactions are:
- The nuclear reaction releases more energy per gram.
- The nuclear reaction takes place in the nucleus of the atom.
- In the nuclear reaction, part of the mass is converted into energy, which violates the law of conservation of mass.
