Practice Exam 3 and Key
Important: Remember to try and learn ALL the material for the exam first. Then, set aside a 2 hour time slot and take the practice exam. Do not use any extra resources, just you, your brain, a calculator, and a pencil.
Note: The cover page with formulas has been separated from the practice exam.
Error on #24 of practice exam. The term "covalent solid" in the question is supposed to be "molecular solid".
