Chemistry Help
Net Ionic Equations

Net Ionic Equations

In this lesson you will master writing full ionic and net ionic equations.  You will learn how to explain which compounds fully dissociate in solution and identify spectator ions in reactions.

Chemistry Help

Moles & Stoichiometry
Formula Weights, Molecular Weights & Mass Percentages

chemistry formula weight, molecular weight

Learn how to determine the formula and molecular weights of compounds and use these weights to calculate mass percentages of elements within the compound.

Molecular Structure and Shape

Molecular Structure & Shape
Lewis Structures

In this lesson you will learn how to draw Lewis structures using a simple five step approach.  You will also explore important exceptions to the octet rule.

Chemistry Lessons
Intermolecular Forces

In this lesson you will learn about the formation and properties of ionic compounds as well as how to compare ionic bond strength via lattice energy.

Intermolecular Forces
Ionic Compounds & Properties

AP Chemistry
Chemistry Kinetics

In this lesson you will explore the factors which affect the reaction rate.

Kinetics
An Introduction to Kinetics

Chemistry Equilibrium

Equilibrium
The Concept of Equilibrium

In this lesson you will explore the concept of equilibrium and how it relates to reaction rates for reversible reactions.

Acid Base Equilibria

Acid Base Equilibria
Acid Base Properties & Definitions

In this lesson you will also explore common properties and definitions for acids and bases.  You will also explore the concept of amphoterism.  You will then use these definitions to predict the products of and write the equations for proton transfer reactions.

Acids and Bases

Advanced Acids & Bases
The Common Ion Effect

In this lesson you will learn about the Common-Ion Effect and how to solve pH problems where a common ion is involved.

Chemistry solubility

Solubility Equilibria
Solubility & Solubility Product

In this lesson you will learn how to calculate solubility and the equilibrium constant (the solubility product) for slightly soluble salts.
