What This Document Is
This document is a first examination for a General Chemistry I with Lab course (CHEM 115) at Western Washington University. It assesses fundamental concepts covered early in the course, focusing on quantitative problem-solving and qualitative understanding of atomic structure and properties. The exam tests the ability to apply chemical principles to calculate values and interpret relationships between measurable quantities.
Why This Document Matters
This examination preview is invaluable for students currently enrolled in General Chemistry I with Lab. It’s particularly useful for self-assessment *before* a similar exam, helping you identify areas where further study is needed. Reviewing the types of questions asked will help you prepare a focused study plan and practice applying concepts in a testing environment. It’s also beneficial for understanding the instructor’s expectations regarding problem setup, units, and significant figures.
Common Limitations or Challenges
Please note that this preview does *not* include the actual exam questions, solutions, or detailed explanations. It is designed to give you a sense of the scope and format of the assessment, but will not provide answers to help you complete your own exam. Access to the full document is required to view the complete examination and its associated solutions.
