Introduction: This course is the second semester of General Chemistry for science,

pharmacy, engineering, etc students. The lectures cover the topics kinetics,

equilibrium, acids, bases, thermodynamics, redox reactions, electrochemistry, and

nuclear chemistry. This material covers chapters 13-16, 18, 19, 23 in the text. Three

exams (given during the lecture period) and a cumulative final are given. The lowest

exam grade is dropped.

current experiment discussed.

The lab experiments supplement and coordinate with the lecture topics. There is a

Lecture: 10:30 AM-12:00 PM Tues. & Thurs. in Room 6068

Semester: Spring 2009

prelab assignment (prestudy) which must be done and handed in the Tuesday before the lab

is done. Points are deducted if late. Lab reports involve filling in the report sheets in the

lab manual, writing a title page, and an abstract page and are due a week after the lab is

done unless otherwise indicated. The lowest prestudy and lab report grades are dropped.

ChemSkill Builder: (online), is required and is worth an exam grade. The assigned topics

must be done online by the due date (day of final exam) for credit (100 points maximum).

The grade is based on overall percent correct of all assigned problems. Missed exams, quizzes or lab experiments will count as a drop.
