Question

Given below are two statements:\ Statement I: Mass-energy interconversion strictly takes place only in nuclear reactions and never in chemical reactions.\ Statement II: The mass defects involved in a chemical reaction are almost a million times smaller than those in a nuclear reaction.

Professor PC Thomas Classes · Answer

A chemical reaction is similar to a nuclear reaction in principle regarding mass-energy interconversion (Statement I is false), but the mass defects are a million times smaller, making them practically unmeasurable (Statement II is true).
