Physical and Chemical Changes
Study Guide Overview
This study guide covers the differences between chemical and physical changes. It explains chemical equations, including reactants and products. It details chemical changes involving intramolecular bond breaking/forming, using examples like burning and rusting. It also explains physical changes as intermolecular changes, such as phase changes, and discusses special cases like dissolving. Finally, it provides review activities, practice questions (multiple-choice and free-response), and an answer key.
