To distinguish between chemical and nuclear reactions, check for mass changes during the reaction.
To determine whether a reaction was a chemical reaction or a nuclear reaction, one way is to check for a change in total mass during the reaction.
In chemical reactions, mass changes are too small to measure due to the laws of conservation of matter and energy, while in nuclear reactions, mass changes are measurable.
Observing the change in mass can help differentiate between chemical reactions and nuclear reactions.
