http://chemwiki.ucdavis,eduTwelve chapters will be covered from the Zumdahl textbook: Chapters 1-8, 10, 11, 13 & 14. Click on the ChemWiki Links for the corresponding ChemWiki pages, which correspond to each topic.
Complete as many end of chapter textbook problems as possible keeping a separate looseleaf notebook for your work, which should be done in writing: legibly, clearly, and organized by textbook problem number. They are to be turned in with each quiz.. Consulting the solutions guide is recommended as necessary. SEE: Zumdahl Table of Contents. Homework & Class Notes will be collected at the end of each quiz and will be factored into the quiz score, that is, an amount of up to 30% of the points lost on the quiz will be added back into that particular quiz grade.
The DVC Chemistry Department provides student tutoring in PS 110 beginning the 2nd or 3rd week of classes. Please consult the schedule that is posted in the labs and lecture rooms.throughout the department for times and tutors.
Each textbook chapter has a Worksheet that relates to the topics in the chapter. These worksheets are to be done collabratively. In some cases you will be assigned to a group, which is responsible for completion of the Worksheet, where each group member receives the same grade. In other cases, you will select your group partners with groups being no larger than four members. You are highly encouraged to form you own study groups from these Worksheet collaborations.

Fritz Haber, Nobel Prize in Chemistry 1918: "for the synthesis of ammonia from its elements"...."From the law of equilibrium it follows that the higher the pressure is the more the equilibrium must shift to the ammonia side. This provided the basic principles. A temperature of about 500° C had to be used at the highest possible pressure, which in practice meant at about 150-200 atmospheres. It could also be assumed that this high pressure speeded up the reaction. But work with a flow of gas in a circulation system at such high pressure and at a temperature approaching red heat posed very severe difficulties and up to then had never been tried. It was, however, completely successful. The treatise in question contains detailed drawings of the equipment used with which, using iron as a catalyst, about 250 grams of ammonia were produced per hour and per litre of contact volume; with uranium or osmium as a catalyst considerably more was produced."

The image gives a hint to the answer of the last question of the worksheet. Click on the image / link for BBC's "tour de force" of WW I. The 80th anniversary of its end was on the 11th hour of the 11th day of the 11th month of 1998. The 11th day of the 11th month is celebrated in the U.S. every year as Veteran's Day. Veterans and anyone who have experienced the horrors of war share an enormous bond of remembrance regardless of the conflict or the country. A WW I's officer's poetry reflects an Englishman's experience in 1918. Read one of his poems, "Dulce et Decorum Est", which also relates to the on-line equilibrium problems last question. A bonus will be given for a correct English translation of the poem's Latin close: "Dulce et decorum est pro patria mori." and explaining why you agree or disagree with this sentiment.
