Gas stoichiometry and mixtures

We worked through a couple stoichiometry problems, including one that required use of the ideal gas law to determine the volume of gas produced by a reaction. These are the same stoichiometry problems that we've been working on for the last couple weeks, they just use different bits and pieces of info to get into and out of moles. We also talked about pressure and how the atomic understanding of "pressure" helps us understand mixtures of gases including Dalton's Law of Partial Pressures.

There is a new Mastering Chemistry assignment, due Tuesday. Exam #2 is next Wednesday. Have a good weekend.
