Question

Which is one way to determine whether a reaction was a chemical reaction or a nuclear reaction?

Answer 1

Answer:

Check for a change in total mass during the reaction.

Explanation:

It is not Check to see if any energy was released during the reaction.

Answer 2

Answer:

B) check to see if any energy was released during the reaction

Explanation:

Energy changes accompanying nuclear reactions are much larger. This energy comes from the destruction of mass. In a nuclear reaction, mass is not strictly conserved. Some of the mass is converted into energy, according to the equation E = mc2 and the order of energy evolved during a nuclear reaction is much higher than that of a chemical reaction. So, one of the significant way to determine weather the reaction is chemical or nuclear is to check how much energy was released during the reaction.
