What This Document Is
This document contains notes compiled to prepare for the first exam in Chemistry (CHEM 110) at California Polytechnic State University, San Luis Obispo. It’s a student-created study resource intended to consolidate key concepts covered in the course thus far.
Why This Document Matters
This study guide is valuable for students enrolled in CHEM 110 who are looking for a focused review of foundational chemistry topics before their first exam. It’s most useful when used *in conjunction with* class notes, slides, and textbook readings. It exists to help students efficiently identify and revisit core concepts.
Common Limitations or Challenges
This document is *not* a substitute for attending lectures, completing assigned readings, or engaging with the course material. It’s a condensed review and may not cover every nuance discussed in class. It also doesn’t provide practice problems with solutions – it’s a content overview, not a problem-solving guide.
What This Document Provides
This study guide includes notes on:
* The definition of chemistry and matter, including mass vs. weight.
* The metric system and common unit conversions.
* Scientific notation and its application.
* Density calculations and its use for identification.
* Metric prefixes (mega, kilo, deci, centi, milli, micro).
* Dimensional analysis and example units.
* States of matter and phase changes.
* Physical and chemical properties, with examples of indicators of chemical change.
* Elements, atomic structure (protons, neutrons, electrons, nucleus, electron cloud), and isotopes.
* Atomic symbols, mass number, and atomic number.
* Calculating average atomic mass.
* An overview of the periodic table (metals, groups, periods, periodic law) and common element symbols.
* Information on laboratory equipment (test tubes, beakers, graduated cylinders) and measurement techniques.
This preview does *not* include detailed explanations of complex calculations, practice problems, or complete coverage of all lecture material. It is a high-level overview of the topics covered.
