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

Explanation: Just took the test on edge :)

Answer 2

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.

Step-by-step explanation:

• Both chemical and nuclear reactions undergoes energy changes.
• In nuclear reactions, the energy changes are massive and measurable compared to a chemical reaction where the changes are not detectable.
• During a nuclear reaction, the total mass of the products is not equal to the total mass of the reactants and hence violates the law of conservation of mass.
• Like in a nuclear fusion reaction between hydrogen nuclei to form helium nuclei, the total product mass is not equal to that of reactants since some mass is converted to nuclear energy.
• However, during chemical reactions, the law of conservation of mass is not violated.
