Instructor: Lecture and laboratory: Dr. R. Wirkkala 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. Weekly quizzes covering current lecture material are given and the lowest quiz grade dropped. In the one hour recitation the quiz is given, questions answered and the current experiment discussed. The lab experiments supplement and coordinate with the lecture topics. There is a 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. 1
