The observation that most likely indicates that only a chemical change has taken place is: **A reaction occurs.**
Chemical changes involve the formation of new substances, which can often be indicated by observing a reaction, such as bubbling, color change, or the formation of a precipitate. In contrast, physical changes, such as changes in shape or state, do not necessarily indicate a chemical change.
