What This Document Is
This is a focused review resource designed to help students prepare for Exam 2 in University of Southern California’s CHEM 105: General Chemistry. It’s crafted as a comprehensive compilation of key concepts and practice problems, intended to reinforce understanding of material covered in lectures and supplemental instruction sessions. The review aims to bridge the gap between theoretical knowledge and practical application, assisting students in confidently tackling exam questions.
Why This Document Matters
This resource is invaluable for any CHEM 105 student aiming to maximize their performance on Exam 2. It’s particularly helpful for students who benefit from a consolidated review of core principles and those seeking to test their understanding with targeted practice. Use this review in the days leading up to the exam as a final check of your knowledge, focusing on areas where you feel less secure. It’s designed to be a focused study aid, complementing your notes and textbook readings.
Common Limitations or Challenges
This review is *not* a substitute for attending lectures, completing assigned readings, or actively participating in problem-solving sessions. It doesn’t provide detailed explanations of every concept covered in the course, nor does it include fully worked-out solutions to every problem. It assumes a foundational understanding of general chemistry principles. It is also specifically tailored to Exam 2 (105a) and may not cover all topics within the broader CHEM 105 curriculum.
