Moles

Main Lesson: Moles

This page explains how to measure in grams, moles, and more! You will learn how to do different types of conversions and problem solving using grams and moles. This page also explains dimensional analysis.

Types of Chemical Reactions

Main Lesson: Types of Chemical Reactions

This page gives a general overview of the different types of equations studied in Chemistry, including single displacement reactions, double displacement reactions, precipitation reactions, combustion reactions, acid-base reactions, and oxidation/reduction reactions (also known as redox reactions).

Stoichiometry

Main Lesson: Stoichiometry

After studying the different types of equations, you’ll run into problems that don’t work because you don’t have the right ratio of one chemical to another. Stoichiometry, also known as balancing equations, helps you determine the right amount of each reactant in order to produce the desired product(s)!

Gas Laws

Main Lesson: Gas Laws

This page starts with the simpler gas laws, Boyle’s Law and Charles’s Law, Gay-Lussac's Law, and Avogadro's Law, and moves on to explaining, and implementing, the ideal gas law (also known as the ideal gas equation). Brief discussion of STP and the ideal gas constant, R, as well as the ideal gas law, PV=nRT.

Bonds

Main Lesson: Bonds

This page identifies different types of bonds, including covalent, polar covalent, ionic, and hydrogen. It explains how to draw compound structures by counting electrons and placing bonds accordingly. The Octet and Duet rules are also explained here.

Electron Configuration

Main Lesson: Electron Configuration

This page details how electrons are arranged in an atom, including information about the orbitals (s, p, d, and f) and how to easily tell which orbital an electron is in. You’ll also learn about the diagonal rule and electron spin.

Lewis Structures and VSEPR

Main Lesson: Lewis Structures and VSEPR

Electron Dot Diagrams, Lewis Dot Symbols, and Lewis Structures are all defined and explained. VSEPR, Valence Shell Electron Pair Repulsion, and Molecular Geometry are also explained in order to determine molecular shape.

Introduction to Organic Chemistry

Main Lesson: Introduction to Organic Chemistry

Introduces carbon structures and interactions between molecules. Basic vocabulary and ideas are introduced concerning alcohols and hydrocarbons. Combustion of a hydrocarbon is also discussed briefly.

General Chemistry Reference Page

Main Lesson: General Chemistry Information and References

This page contains a ton of information that is largely relevant to the study of chemistry, including the solubility rules, a list of common conversion factors, equations, and an ion list. Please see other pages for explanations of these terms and equations; this is purely for you to go back and quickly use as a reference guide after you understand the basic principles.
