Final answer:
Boiling water is not a chemical reaction but a physical change, as it involves the phase transition from liquid to gas without any change in chemical composition.
Step-by-step explanation:
Rewriting the equation using chemical names, boiling is described as the transformation of water from liquid to gas phases. This is represented by the equation: H2O (l) \u2192 H2O (g), where (l) represents the liquid state, and (g) represents the gaseous state. Boiling is not a chemical reaction; it is a physical change because no chemical bonds are broken or formed during the process.
To answer the student's question directly, boiling is No, not a chemical reaction. Therefore, the correct option is b. No.
