Stoichiometry

http://www.chemtutor.com/mols.htm#road A site that explains stoichiometry and has a number of practice problems with answer to check your work.

http://dbhs.wvusd.k12.ca.us/Stoichiometry/Stoichiometry.html Another site the explain stoichiometry a little more simply, and explains how to find moles given moles, grams, given moles, moles given grams and grams given grams. Some good practice problems.

http://www.chemtopics.com/unit03/unit3f.htm A site with practice problems for both mole to mole conversions and gram to gram conversion. Answers are included as well as some practice tests.

http://www.hn.psu.edu/faculty/dmencer/stoichiometry/stoich.htm These pages are designed to familiarize the user with some of the stoichiometric concepts and calculations used when dealing with chemical reactions.  These concepts and calculations can be addressed through the use of some reaction simulations. The simulations are designed to obey the stoichiometric principles.

http://go.hrw.com/resources/go_sc/ssp/HUGPS084.PDF  A miniguide to problem solving stoichiometry problems with practice problems and diagrams.

Kinetic Theory

http://www.riverdeep.net/science/chemistry_explorer/ce_activity_pages/catn.activityi_291.jhtml                         Watch gas molecules in random motion colliding with the walls of their container. Interpreting their observations in terms of the kinetic theory of gases, they relate the number of walls-molecules collisions to the gas pressure and examine the graph of pressure (number of wall collisions) vs. time.

http://zebu.uoregon.edu/nsf/balloon.html   In this website you can interact with a balloon's pressure and the molecules in the balloon to see what happens to the balloon. You raise the temperature in the balloon to see what happens. Then answer the questions following each experiment. There are six pages of experiments.

http://jersey.uoregon.edu/vlab/Thermodynamics/index1.html  In this interactive experiment you will discover what temperature does to the mixing particles that come from different chambers with different temperatures.

http://zebu.uoregon.edu/nsf/piston.html In this series of experiments, you will control the action of a piston in a pressure chamber which is filled with an ideal gas. The gas is defined by four states.
