One way to determine whether a reaction was a chemical reaction or a nuclear reaction is to **check for a change in total mass during the reaction**.
In nuclear reactions, according to Einstein's theory of relativity (E=mc²), there can be a measurable change in mass, as a portion of mass is converted into energy. In chemical reactions, the mass remains essentially unchanged, although individual atoms may rearrange.
So, the correct answer is:
**Check for a change in total mass during the reaction.**
