Chem. 1B – 12/8 Lecture

Announcements I Mastering Final Exam Ch. 20 assignment (Organic Chemistry) due 12/10 After that (and the hand grading problem), I will assign class points (probably some bonus to reflect some bad homework problems) Final Exam Thurs., 12/15 12:45 to 2:45 42 multiple choice questions (2 bonus, but no work out type) Using SC-982E Scantron form (Blue version used previously)

Announcements II Final Exam – cont. About 4 questions each for Ch. 14, 15, 17, and 24 and about 8 questions each for Ch. 16, 18, and 20 Less calculation intensive than exams 1 and 2 Sect. 7 in Lab room (Sequoia 426)
