Unit 5: Chemical Reactions
Bonding is now firmly established; so students can progress to learning how bonds break and form in chemical reactions. Different types of chemical reactions are explored in both direct instruction and virtual laboratory experiences. Students learn the fundamentals of products and reactions and learn to balance equations to show that mass is conserved as change happens in these reactions.

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.

SEMESTER TWO
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.

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.

Most students entering chemistry have some experience with acids and bases from everyday life. In this unit; after examining the properties of acids and bases; students analyze different definitions of acids and bases that have been developed since the time of Arrhenius. They learn how to solve problems dealing with the strength of acids and bases. Students gain practical experience working with acids and bases in a virtual laboratory setting; including doing titrations.

Unit 4: Chemical Thermodynamics
A vital part of the study of matter is learning about the energy associated with both chemical and physical changes. The study of energy in chemical systems is called chemical thermodynamics. It involves understanding that energy is conserved during chemical reactions and also when substances change from gas to liquids to solids—and back again. Overarching all this content is the law of conservation of energy.
