Now that students understand the basics of chemical reactions and the ability to balance chemical equations, it is possible for them to apply this knowledge to real-world situations. Stoichiometry is the study of determining the yields of chemical reactions, given the masses of some parts of the chemical equation. Mastering this allows students to solve problems similar to those that confront chemists in industrial production.

Unit 1: States of Matter

The study of gases, liquids, and solids not only tells us of their properties, but gives us a strong basis for understanding how matter is organized and how it behaves. Students closely examine how a volume of gas behaves under changing conditions of pressure and temperature. Students also investigate some of the properties of liquids and solids, and relate all three states of matter using phase diagrams.

  • Semester Introduction
  • The Behavior of Gases
  • Gas Laws
  • Review: Gases
  • Optional Laboratory: Gas Laws
  • The Ideal Gas Law
  • Absolute Zero
  • Review: Ideal Gas Law

Unit 2: Solutions

Much of chemistry involves understanding solutions, in which a solute is placed in a solvent. The properties of the resulting solution can be understood by examining the interactions between the parts of a solution. Students learn the various ways to describe the concentration of solution and how to separate the component substances.

  • Solutions
