select the correct answer. which of the following is a chemical reaction? a. breaking a glass pane b. freezing water c. digestion of food d. cutting down a tree e. evaporation of rubbing alcohol

Answer

Brief Explanations:

A chemical reaction results in the formation of new substances with different chemical properties. Breaking a glass pane, freezing water, cutting down a tree, and evaporation of rubbing alcohol are physical changes as they do not change the chemical composition of the substances. Digestion of food involves chemical reactions where complex food molecules are broken down into simpler ones by enzymes.

Answer:

C. digestion of food
