This Week's Selections
Last Week's SelectionsPeriodic Trends of the Elements This page covers the contribution of Mendeleev and Moseley to the development of the modern periodic table. It also has a brief discussion of the fundamental trends in element and atom properties.
The Periodic Table A brief discussion of the organization of the periodic table.The Periodic Table Gives information on the elements and goes over the periodic nature of properties.
The Periodic Table A tutorial on the periodic table and periodic properties.
Atoms Ions A good discussion of atoms and the history of the development of the atomic theory. It has Learning Objectives, Lecture Notes, References and Resources, and Glossary.The Atomic Theory of Matter This is a brief discussion of the history of the discovery of the components of an atom. Much of this material is not needed for CHM1025.
Atoms and Elements A short discussion of atoms, elements, isotopes, and the periodic table. It includes many links with the discussions.
This Week's
Selections
- Behavior
of Gases This page covers the full range of topics that we will discuss
regarding gases: Boyle's, Charles', Gay Lussac, and the combined gas laws.
It the goes over the ideal gas equation and the important of the ideal
gas constant, R. It finishes with a discussion of the Graham's Law
of diffusion and "real" versus "ideal" gases.
Ideal Gases A 20-page document that gives a fairly complete coverage of the subject, with more attention than normal to kinetic theory. Also treatment of applications (e.g., why the sky is blue) that don't seem to get included in most books. To view this document you will need to download Adobe Acrobat.
Chemistry Problem Solving-Gases This page shows how to solve problems that involve gases. It includes Ideal Gas Law, Dalton's Law, and Mole Fraction.

The following are exercises to practice writing half reactions and balancing redox requations: Exercise 1 - Writing Oxidation Half-Reactions, Excerise 2 - Writing Reduction Half-Reactions, Excerise 3 - Chemical Formula Writing, Excerise 4 - Determining Oxidation States, Excerise 5 - Oxidation States of Nonmetals, Excerise 6 - Combination/Decomposition Reactions, Excerise 7 - Single Displacement Reactions, Excerise 8 - Disproportionation Reactions, and Excerise 9 - Balancing Redox Equations.Practical Examples of Redox Reactions: Bleaching Agents, Photosynthesis, Metabolism, Nitrogen Fixation, Electrochemistry, Combustion of Fuels, Refining Metal Ores, The "Dry Cell" Battery,
Photo-oxidation (Photogray ® Glasses), and Corrosion.Oxidation-Reduction Reactions Covers the basic information about redox reactions, oxidation numbers, and balancing redox equations.
This Week's Selections
Rates of Reactions This is an excellent place to begin the topic of chemical kinetics. It has an introduction followed by a discussion of the rate law. It then covers the collision theory and the effect of temperature on reaction rates. It finishes with a discussion of catalysis.
Kinetics A very complete discussion of all aspects of reaction rates and chemical kinetics. A good place to begin your study of chemical kinetics.
Kinetics This is an interactive discussion of rate expressions. You can experiment by changing the values of the concentrations and rate constants.
Kinetics: Orders and Rate Constants Describes reaction orders and rate constants. Again calculus is used.
