Wednesday, October 21


Tuesday, October 20

  • Problem Set #10 is posted on Sapling Learning. It will be due next Tuesday (10/27) at 9pm.
  • If you have not already, please begin reading and working problems from Chapter 9. The worksheets Reactions 3 & 4 and Stoichiometry 1 are good extra practice problems for you to be working now.


Sunday, October 18

  • New Notes posted. Please PRINT or have access to for lab/lecture this week.
  • Please see the calendar for my office hours this week. Due to various meetings and other obligations, I have had to move some times around, including my Tuesday morning office hours.
  • Current Grade Posting
    • The Percent reflects your current percentage in the course for all graded items. There are still lab items that will be returned this week and will be added to the next grade posting.
    • The Projected ADJUSTED Percent reflects the adjustments that will be applied to the Percent in order to arrive at the percentage that your course grade will be based on. The adjustments made are as follows:
      • Your lowest Sapling problem set score is dropped.
      • The lowest exam score is replaced by an average of that exam score, the next highest exam score, and the highest exam score. This will helped to mitigate the overall impact of a missed or very low exam score on your final grade.


Monday, October 12

  • See the lecture page for updates to the extra practice worksheets. The worksheet titles in boldface type will be directly covered on Exam #3.


Friday, October 9

Pre-semester Announcements

  • Welcome to CHEM 192 - Introductory Chemistry. I am looking forward to a productive, challenging, and rewarding semester.  There is important information below that I would like to share with you regarding the start of the semester.
  • Be sure to familiarize yourself with the links on the left side of this page. They will take you to most of the course online content.
  • Enrolled students: You are all set! Attend LECTURE on the first day of classes, Monday, August 17 and the LABORATORY class you are enrolled in on Monday, August 17 or Wednesday, August 19.

    IMPORTANT: If you are enrolled in the course, attendance at your assigned laboratory section during the first two weeks of classes is required to make sure that you maintain your enrollment!
  • Waitlisted students: If you are on the course waitlist, continue to check your email up to the first day of classes to see if a spot opens for you. If it does not, attend the lecture classes and the laboratory for your preferred lab section during the first week of classes. Over the course of the week, I will be able to give you a good indication of the possibility of adding to the course.

    IMPORTANT: During the first two weeks of classes, attendance at the MWF lectures and either the Monday or the Wednesday laboratory section is required to maintain your waitlist priority.
  • Academic integrity will be be taken very seriously in the course. All students are expected to act with respect and honor codes of student conduct. This topic will be addressed in detail in the first two weeks of classes in lecture and in lab. Please scroll down on this page to read Skyline College academic honesty information.
  • Course Materials:

    • Please see the SYLLABUS for a complete listing of all of the required course materials.

    • The REQUIRED course LECTURE textbook is
      Introductory Chemistry: A Foundation, 7th or 8th Edition
      by Zumdahl & DeCoste

      • The 7th edition ISBN-10: 0538740523 or ISBN-13: 978-0538740524
        This will help you find it online.

      • The 8th edition is available in the bookstore and from various online sources.

      • We will begin using the textbook in the course right away, and it will be important that you have it. If you plan to purchase online, please do so as soon as possible.

      • Please begin reading the assigned readings from Chapters 1, 2 & 3, and working problems at the end of the reading sections. See the LECTURE page for assigned readings.

    • The REQUIRED course LABORATORY NOTEBOOK is a dual-copy, bound, numbered laboratory notebook. An appropriate laboratory notebook for chemistry courses is sold in the Skyline College Bookstore.

  • Sapling Learning - Orientation & Problem Sets

    • A Training Video & Practice Problem Set are posted under the Introduction section.
      They are not required, but I think you will find it helpful.

    • The first Graded Problem Set is posted under the Problem Sets section. See the course calendar and/or Sapling site for the due date/time.
      • For this problem set, you have UNLIMITED attempts to answer each question with NO POINT DEDUCTION.

There are files better for viewing on computers or other electronic devices and others intended for printing. Choose the format that is bet for you.
  • Extra Practice Worksheets are posted on the LECTURE page. We will use these for in-class practice or for out-of-class reinforcement of chemical concepts and problem-solving.


Academic Integrity

  • Academic integrity is an important issue in all academic settings, and will be taken very seriously by the instructor of this course, and the college generally.

  • I recognize that most students conduct themselves with honesty and integrity. I also recognize that the actions of a few dishonest students and the impact of those actions on the academic process necessitate a frank and ongoing discussion of this issue.

  • Please review the Student Handbook information on Academic Integrity.



  • The prerequisite for CHEM 192 is:
    • Successful completion (C or better) of MATH 110 (Elementary Algebra) or equivalent.
  • Please speak with me if you have any questions regarding your preparation for the course, or to if you wish to discuss whether another course is better suited to your academic preparation or goals. Please also ask if you have questions about prerequisites or the petition process.
