Question

PLZ HURRY I NEED THIS ANSWER LIKE... NOW

Which is one way to determine whether a reaction was a chemical reaction or a nuclear reaction? (2 points)
a)Check for a change in total mass during the reaction.
b)Check to see if any energy was released during the reaction.
c)Measure the temperature change during the reaction.
d)Measure the total volume of gas released during the reaction.

Answer 1

Check for a change in total mass during the reaction. During the change to a chemical reaction, the mass of the products remain equal, which results in no change of the mass. The mass will change during nuclear reactions because of the large release of energy; that results in the difference of the accumulation. ^_^
