103 Matter, Physical/Chemical Changes, the Atom, Isotopes Review
This is a review of chapters 3 & 4. The topics covered include physical and chemical changes, physical and chemical properties, mixtures, separation of mixtures, pure substances, elements, compounds, isotopes and Rutherford model of the atom. It is recommended that you work the review sheet first then check your answers and then scroll to the question number that you need help with in the video. You have to practice in chemistry, working the review sheet first will help you to identify what concepts you need to focus on the most while studying.
