Final Exam day and time: https://www.gccaz.edu/sites/default/files/imce/become_a_student/docs/fall_17_final_ex am_sched.pdf Course Description: A study of the chemical properties of the major groups of elements, equilibrium theory, thermodynamics, electrochemistry, and other selected topics. This course is a study of the chemical properties of the major groups of elements, equilibrium theory, thermodynamics, electrochemistry, and other selected topics. Prerequisites: A grade of C or better in [(CHM150 or CHM151) and CHM151LL], or CHM150AA, or CHM151AA. Completion of prerequisites within the last two years recommended. Course Notes: Completion of CHM152LL required to meet the Natural Science requirement. Student may receive credit for only one of the following: CHM152 and CHM152LL, or CHM152AA Lab is a separate 1-hour course (you receive a separate grade for lecture and lab), and you must enroll separately for lab. You do not need to have the same instructor for lecture and lab, although you may find it to be beneficial to do so.

(VI) Textbooks, Materials, and Technologies: Required - Free Textbook: We will be using a free online electronic textbook (a hard-copy textbook is NOT required for this course.) The text is Chemistry available from OpenStax, at https://openstax.org/details/chemistry Required - Free Online homework: We will be using MathAS (an online homework program: https://mathas.pvc.maricopa.edu/) for this course. Online homework assignments are required. They are graded and are due as posted on Canvas, this syllabus, and the MathAS website. Course ID: Enrollment Key: Recommended - Calculator: A non-programmable calculator (basic or scientific) capable of computational and exponential functions will be necessary for homework and exams. Common uses will include scientific notation, logarithms (natural and base 10), exponents, and x-roots. Programmable calculators will not be permitted on quizzes or exams (the department has calculators you can borrow). Recommended - The following resources are available on Canvas and other instructors sites. PowerPoint slides available on my website: web.gccaz.edu/~ debis71431/chm152.html - you may find these useful to print out (as handouts, ~ 6 slides per page) and bring to class. Worksheets with answer keys on my website: web.gccaz.edu/~ debis71431/chm152.html - students typically find these very helpful when studying for exams. These are NOT graded. Chapter Reviews (by Dr. Smith): web.gccaz.edu/~kimld88531/rev152.htm - another helpful resource when studying for exams. Extra Help Links: From Dr. Smith s page (web.gccaz.edu/~kimld88531/help.htm#152) and Dr. Diebolt s page (web.gccaz.edu/~lisys52871/). Attendance Requirements: Attendance in lecture is mandatory and necessary for adequate performance in the class. Attendance will be taken daily. Anyone not enrolled in the class may not attend (liability issues). Therefore, you may not bring children to class (call Child Care Resources and Referral Service (602-244-2678) for free help finding last-minute State-approved day care). Anyone with 6 or more absences will be withdrawn from the course if you do not contact me first. If you take the final exam, you will be assigned a letter grade for the course! Syllabus: CHM152 General Chemistry II Sections 20319/20321 Fall 2017 Instructor: Leedy page 2 of 7
Withdrawals: I will withdraw anyone who misses 6 classes without talking with me. Grades of I are given only under extreme circumstances if the student requests it in writing, meets with the instructor, provides documentation, and the instructor approves it before the final exam. If you withdraw from lecture before October 27 th you must also withdraw from the lab. Students who take the final exam are not eligible to receive a W or Y. It is the responsibility of the student to drop the course before the deadline for student-initiated withdrawal. Students should use the Student Information System (SIS) to withdraw from the course. The instructor may drop a student for excessive absences (as defined by the instructor) with a grade of W. The deadline to withdraw from lecture is the day the third exam is graded and passed back. Students may not withdraw after that date a letter grade (A-F) will be assigned. Note: A grade of Y may be assigned for students caught cheating. A grade of Y counts as an F in your and cannot be replaced by retaking the class. Students who take the final exam are not eligible to receive a W or Y. Grading Standards & Practices: (It is your responsibility to elect to take this course Pass/Fail at the beginning of the semester.) You can check your grades throughout the semester on Canvas. Grades are updated about once a week. Emails sent after the final exam asking for extra credit will be deleted. The final exam is the last graded assignment.

The dates of the exams are listed on the course outline on the next page. Each exam is worth 100 points and they will all count toward your final grade. Exams are taken in class. Each exam will cover two chapters. Questions will be in order of topics covered in class. Question formats can include but are not limited to: multiple choice, calculation, short answer, graphing/interpretation, drawing solutions. Make-Up Exams: None of the hour exams will be dropped. Therefore, it is imperative that you be present for every exam and plan travel and other events accordingly. If university-sanctioned travel or excused events do interfere with an exam date, then it is your responsibility to contact me BEFORE the scheduled exam and take the exam BEFORE the regularly scheduled time. All exam dates are scheduled at the beginning of the semester. If you miss an exam due to extreme, but documentable, emergencies, your final exam percentage will be substituted for the missed exam. Group Quizzes: Unannounced 10-point group quizzes or individual quizzes will be given during lecture. It is in your best interest to attend every class. These quizzes will be graded on a 10-point scale. Make-up quizzes will be allowed if I am notified before an absence (via email or phone). It is your responsibility to schedule a make-up quiz; you have up to two weeks to make up a missed quiz. More than 17 quizzes will be given, but only the top 17 scores will count toward your final grade. Syllabus: CHM152 General Chemistry II Sections 20319/20321 Fall 2017 Instructor: Leedy page 3 of 7
Chapter Quizzes: There will be a 5 question, multiple choice, individual, in-class quiz covering main concepts from the chapter the class meeting after we finish each chapter (except for Nuclear which will not have a quiz). Questions will primarily be conceptual, but there will be a few short calculation questions. The lowest chapter quiz grade will be dropped at the end of the semester. Homework: Graded homework exercises (MathAS) will help you gauge your understanding of the material presented in each chapter. Homework assignments will be scored out of 20 points, except for Nuclear which will count for 10 points. The assignments will have about 10-15 questions. Your score on each assignment will be scaled to 20 points. How to access homework will be covered the first day of class. Final exam: The final exam will be a 50 question, cumulative, multiple choice exam. It will be worth 200 points. If you take the final exam, you will get a letter grade for the class. Not graded: Worksheets: Additional worksheets are available on my website as extra practice material to help you study. They will NOT be turned in or graded, although they will be helpful for you. Answer keys to the worksheets are posted online. Sources of Help: In addition to my office hours listed above, our department has an open door policy. If an instructor s door is open and they have the time and willingness to help with 152 material, you are welcome to ask questions. We also offer free tutoring (Chemistry Solutions) Monday Friday in HT-2 Pit (east end) from 9 am 5 pm. The exact schedule will be posted on the department website.
