All materials associated with chem 152B are copyrighted and may not be stored or distributed in anyway.

This is a general chemistry course intended primarily for students who are concentrating in the science area. Chemistry 152 builds upon the concepts and laboratory skills introduced in Chemistry 151. Student proficiency in algebra is assumed. Prerequisite: Chemistry 151.

Given that chemistry 152 is a college-level course, it is expected that a student will spend approximately four-to-six hours per week working OUTSIDE OF CLASS for the theory (lecture) component of chemistry 152. The time required typically depends on one’s preparation in chemistry before taking this course, the complexity of the material, and other factors. Work time OUTSIDE OF CLASS includes, but is not necessarily limited to, reading the text and/or watching videos and/or working problems contained therein, working quiz preparation (qp) problems, preparing for quizzes and/or exams and, if the student has questions or comments, consulting with chemistry instructor(s).

Luther College recognizes the importance of diversity within the classroom and is committed to providing an inclusive environment where all feel respected, valued and accepted. Scientific advancement occurs when individuals collaborate and bring different ideas together. Each individual’s unique viewpoint and experiences bring important elements to the discussion of science, and accepting and embracing this diversity and will help in understanding the complex world in which we live.

Guidelines for Use of Electronic/Wireless Devices:

The Luther Code of Conduct ( section on “Proscribed Conduct”) indicates that “Students are required to engage in responsible social conduct that reflects credit upon the Luther College community and to model good citizenship in any community;" Article III, section B, point 7 indicates that “[d]istruption or obstruction of teaching” is prohibited behavior. Unless otherwise indicated by the instructor, the lecture and laboratory periods are meant to be times of academic activity related to the course. Cell phones, laptops, and/or other electronic equipment may be used only when specifically instructed to do so by the instructor. Students should check cell phones and/or other electronic equipment for messages before or after class/lab, not during class/lab. Cell phones should be set to “off” or “vibrate” during the class/lab period unless an emergency call is anticipated. All activities in class are to be geared toward the work at hand. The instructor has the right to ask a student to leave the classroom or laboratory if the student’s behavior is distracting to the instructor and/or to other students; repeated problems may cause the instructor to report the situation(s) to a Student Conduct Administrator ( section on “Code of Conduct Procedures”) or to the Department Head or Dean of the College. A student has the right to ask a fellow student to stop engaging in distracting behavior. If needed, a student may report a problem to the instructor, the Department Head, the Dean of the College, or to a Student Conduct Administrator.

Only materials assigned and/or provided for this course for this semester may be used unless otherwise indicated by the instructor. Use of materials from past years of Mertzenich's Chem 152 class is prohibited. The Honor Code must be observed.

Videos and audio clips are for the use of Luther College Chem 152 students only; they are not to be distributed to any other persons, and they are not to be saved or kept by Chem 152 students. Videos and audios are not to be copied, stored, transmitted, and/or posted on any website or in any way. No one may record audio or video of classes without the permission of the instructor. The Luther College Honor Code must be observed. All materials: copyright Claude Mertzenich.

No written, oral, and/or electronic materials provided in this lecture section of Chem. 152 may be shared with anyone not affiliated with this lecture section. All materials are restricted to the use of students and authorized guests of Chem. 152.



The instructor will communicate with the class as a whole outside of lecture or lab time primarily via email sent to your Luther email address. Sometimes documents and other information might be posted on Katie. Scores will be posted on Katie asap.


In general, the lecture period is the time when new material is discussed, although questions about quiz preparation problems or questions/comments concerning an upcoming exam are sometimes entertained after the new lecture material has been encountered on any given day. Questions about grading and points on quizzes and exams should be discussed with the instructor privately in the instructor's office or via telephone or email. Attendance may occasionally be taken and count toward the quiz/attendance/other component of the course.

Anticipated Schedule

Click here for the course master schedule. Other information can be found on the course katie site. We essentially cover all of text chapters 12-17 and (sometimes) part or all of chapter 21.

Material to be mastered by the student: Text section 11.4 will be covered via the lab experience. Chapters 12-17 & (possibly) 21 are anticipated to be covered in the class portion of the course.

If class needs to be cancelled, the instructor will contact the students by email. Otherwise, class is anticipated to meet during the regularly scheduled times.

Exam dates will be posted on the daily schedule.

Final exam. There will be a comprehensive, cumulative final exam during final exams week. The final exam will cover material from all of Chem 152. The date and time of this exam are set by the registrar. Let your instructor know if you will have a conflict (more than 3 exams scheduled within a 24 hour period during finals week). Except in cases of College-approved family or personal emergencies, all students are required to take the final exam at the time scheduled; out of fairness to all of the students in the class, no other exceptions will be made; make your end-of-semester transportation arrangements accordingly.


Check the laboratory Katie site (maintained by Professor Winsauer) regularly for laboratory information. The lab syllabus is on the lab Katie site,

Quiz preparation (qp) problems

QP problems will be assigned on the daily schedule. Time to do quiz preparation problems and associated reading is about four-to-six hours per class period.


Exams (3 of them during class period): 50%
Quiz/attendance/other (3 lowest scores will be dropped): 10%
Final Exam (comprehensive for chem 152): 20%
Laboratory: 20%
Total: 100%

The grading policy in this course is results-oriented. If a student can achieve the course goals with no effort at all, she/he can take pride in achieving results efficiently. If a student requires tremendous effort to achieve the course goals, she/he can take pride in overcoming adversity. Each of those is commendable in its own way, but in neither case will the degree of effort be reflected in the grade.

After all of the graded components (tests, HW, quizzes, labs, and final exam) are weighted into the average score, adjustments are made to ensure that this average is at least a B-. Scores are never curved down, so that a final average will always yield a letter grade at least as high as shown on the table below. Please note that all Chem 152 lecture sections will use the same text and have a common laboratory experience. The scores from only this section will be used to determine the average for this lecture section. There is no "extra credit" available. The following grading scale will be used.

A: 93-100%
A-: 90-92%
B+: 87-89%
B: 83-87%
B-: 80-82%
C+: 77-79%
C: 73-76%
C-: 70-72%
D+: 67-69%
D: 63-66%
D-: 60-62%
F: 0-59%

Scores, grades, etc., will usually be posted on Katie.

Lab and lecture schedules are subject to modifications, as is staffing. Everything else on this syllabus is final.
