What This Document Is
This document is a practice exam and accompanying study guide for the first exam in Brigham Young University’s General College Chemistry (CHEM 105) course. It’s designed to help students assess their understanding of foundational chemistry concepts covered early in the semester. The practice exam consists of multiple-choice questions.
Why This Document Matters
This resource is valuable for any student enrolled in CHEM 105 preparing for the first major assessment. It provides a realistic preview of the question style, content focus, and difficulty level expected on the actual exam. Utilizing this practice exam allows students to identify knowledge gaps and concentrate their studying on areas needing improvement. It’s most effectively used *after* initial coursework and study of core materials.
Common Limitations or Challenges
This practice exam is a sample and does not encompass *all* possible topics that may appear on the official exam. It’s a tool for self-assessment, not a guarantee of specific questions. Students should not rely solely on this document for complete exam preparation; it’s meant to supplement, not replace, textbook readings, lecture notes, and other study resources.
What This Document Provides
The full document includes:
* A 12-question multiple-choice practice exam covering topics such as element properties, chemical vs. physical changes, kinetic energy, mass conversions, experimental accuracy and precision, the law of definite proportions, blackbody radiation, the Bohr model of the atom, and basic stoichiometry.
* Questions testing conceptual understanding rather than direct calculation.
* A range of difficulty levels to challenge students’ comprehension.
This preview *does not* include the answer key or detailed explanations for any of the questions. It also does not include a comprehensive list of topics covered in the course beyond those represented in the sample questions.
