Naming inorganic compounds
AP CHEMISTRY TEACHERS – WE HAVE RESOURCES FOR YOUR ENTIRE CLASS TO USE… Identify if a compound is covalent or ionic You will need to know the periodic table You must be able to identify the non-metals, metals, and transition elements in the periodic table You must be able to categorize a compound as ionic…

Learn the rules for ionic compounds
Background: How ionic compounds are formed Ionic compounds are formed from the electrostatic attraction of oppositely charged ions. The ions are arranged in such a way that they form a giant crystal lattice of alternating positive and negative ions. An example of an ionic compound is sodium chloride, NaCl, also commonly known as table salt….

Learn the rules for covalent compounds
Covalent compound A covalent compound involves two non-metals forming a chemical structure together. Rules What are the rules for naming covalent compounds? • Covalent compounds involve multiple non-metals • Covalent compounds use prefixes – to indicate the number of atoms of each element in the compound • The element that further left of the periodic…

Integrated Rate Laws
Overview There are two types of rate laws that we need to learn for AP chemistry: (1) Differential rate law (2) Integrated rate law What is the difference between the differential rate law and integrated rate law? The differential rate law is actually a derivative of the integrated rate law. In experiments: Differential rate law…

Differential Rate Laws
Methods for determining order of reaction This section looks at how concentration affects reaction rate. You will learn how to determine the order of a reaction. Reactions are often categorized into first, second, third order, etc. and this information is useful for showing the mathematical relationship between concentrations and rates. Rate laws may be written…

Rate of reaction
Measuring rate This section aims to cover the following topics: Define chemical reaction rate Define rate expression Relative rates of reaction and stoichiometry ratio Change in concentration over time The rate of a chemical reaction can be thought of as the speed at which a chemical reaction happens and this can be expressed as the…

Mechanisms and Intermediates
Reaction mechanism Chemical reactions often take place in multiple steps and it’s not always obvious from looking at the chemical equation. For example, the decomposition of ozone: From the equation, it appears that O₃ decomposes to O₂ in one step. In reality, it’s more likely to take place in the following sequence: The above shows…

Introduction to Chemical Kinetics
Energy Kinetics involves studying what makes chemical reactions happen. Every reaction that happens involves some energy exchange, whether it’s slow reaction such as iron rusting, or a faster reaction, such as when a rocket burns fuel during take off.
