Multiple Choice
Most teachers will agree that a perfect answer key is rare. The reasons are as numerous as the errors: typos, strained eyes, misread questions, etc. If your answers do not agree, consult a good chemistry teacher about any questions you might have. I would appreciate knowing about any errors that you might find.
