Are you confused by all the topics in high school chem class? Here is an overview of what is studied in high school chem, with links to essential chem resources and worked chem problems.

Introduction to Chemistry
In order to study high school chem, it's a good idea to know what chem is.
What Is Chem?
What Is the Scientific Method?

Math Basics
Math is used in all the sciences, including high school chem class.

To learn chem, you need to understand algebra, geometry, and some trig, as well as be able to work in scientific notation and perform unit conversions.
Accuracy & Precision
Significant Figures
Scientific Notation
Physical Constants
Metric Base Units
Derived Metric Units
Metric Prefixes
How to Cancel Units
Temperature Conversions
Calculate Experimental Error

Atoms and Molecules
Atoms are the basic building blocks of matter. Atoms join together to form compounds and molecules.
Atom Basics
Atomic Mass & Atomic Mass Number
Types of Chemical Bonds
Ionic and Covalent Bonds
Oxidation Numbers
Lewis Structures and Electron Dot Models
Molecular Geometry
What Is a Mole?
More About Molecules & Moles
Law of Multiple Proportions

Stoichiometry describes the proportions between atoms in molecules and reactants/products in chemical reactions. You can use this information to balance chemical equations.
Types of Chemical Reactions
Balance Equations
Balance Redox Reactions
Gram to Mole Conversions
Limiting Reactant & Theoretical Yield
Mole Relations in Balanced Equations
Mass Relations in Balanced Equations

States of Matter
The states of matter are defined by the structure of matter as well as whether it has a fixed shape and volume. Learn about the different states and how matter transforms itself from one state to another.
States of Matter
Phase Diagrams

Chemical Reactions
There are several different types of chemical reactions that can occur.

Reactions in Water
Types of Inorganic Chemical Reactions

Periodic Trends
The properties of the elements exhibit trends based on the structure of their electrons. The trends or periodicity can be used to make predictions about elements.
Periodic Properties & Trends
Element Groups

It's important to understand how mixtures behave.
Solutions, Suspensions, Colloids, Dispersions
Calculating Concentration

Gases exhibit special properties.
Ideal Gases
Ideal Gas Law Problems
Boyle's Law
