Tuesday, November 29

  • I am not feeling well and will not be on-campus today, so I will not be available for office hours. However, I will be taking questions by email.
  • Reminder: Exam #4 will be held in LECTURE tomorrow, November 30.
    • I plan to be back on campus tomorrow, and have made arrangements for the proctoring of the exam and for lab in case I am not.


Wednesday, November 23

  • Experiment #11
    • We will perform Experiment #11 on Monday & Wednesday in lab. The prelab assignment is due at the start of the lab session. I will be checking your notebook to confirm that it includes the required elements of the PRELAB assignment: PURPOSE, REACTIONS, & the DATA TABLE. Be sure to have these completed so that you may perform the experiment.

  • Exam #4
    • Exam #4 will be held in LECTURE on Wednesday, November 30. This is a postponement due to the district web server failures on Tuesday.

  • Hot Air Balloon and Poster
    • The Hot Air Balloon Due Date & Flight Date is Friday, December 2 in LECTURE. Attendance is required, and it is a lot of fun to see your balloon fly and watch your classmates’ balloons!
    • I will have the lab open from ~11:15-11:55 for you to mass your balloon on that date (you are welcome to mass your balloon earlier in the week as well).
    • The flights will be conducted in the Building 7/8 Quad. Please plan to meet there as close to Noon as possible. We may run over by ~15 minutes to get all of the flights completed. Please be prepared for that possibility.
    • The poster will be due on Friday, December 9 in LECTURE. (Please note that this is the last day of lecture.)
      • We will be spending lecture time in the coming weeks discussing gas laws and the balloon calculations specifically. However, you should be able to do all of the other elements of the poster prior to that discussion. Please note that all of your dimensions should be in metric units, as with all of our measurements in science!
    • I will not be collecting a progress report on the balloon.

  • Problem Set #11
    • Problem Set #11 is posted. We have covered almost all of the material needed to answer these questions. This will be the last graded problem set of the semester.


Friday, November 11

  • PS #9 is posted. It will be due Saturday, November 19 at 9pm. I'll also be posting PS #10 later today. It will be due on Tusday, November 22.
  • Additional worksheet answer keys are posted on the LECTURE page. The worksheets with titles in boldface will be covered on Exam #4.


Sunday, October 30

  • Please see the course calendar for this week's lab activities.


Sunday, October 23

  • Reminders for this week:
    • The Experiment #5 (MgO) Report is DUE at the start of your lab session this week.
    • Please also prepare the Experiment #6 Data Table in your lab notebook prior to your lab session, and bring the printed experiment #6 handout to lab with you.
    • Sapling Problem Set #7 is due Thursday at 9pm.
    • Exam #3 will be held in lecture on Friday, October 28 (see below for more information).


Saturday, October 22

  • Reminder: Exam #3 will be held in lecture on Friday, October 28

    • We have completed lecture material on Formulas & Naming, including IONIC, COVALENT, and ACID Compounds (relates to Chapter 5) and on Moles and Empirical & Molecular Formulas (relates to Chapter 8). These topics will be covered on Exam #3.

    • We are now covering Chemical Reactions & Equations in lecture.
      • We began with directly covering General Concepts & Balancing Chemical Equations (relates to Chapter 6) on Friday and we will discuss Solubility Rules (relates to Section 7.2) on Monday.
      • We also began Classifying Reactions in lecture on Friday and will complete this discussion on Monday. This relates to material in the rest of Chapter 7. However, Chapter 7 makes the classifications a bit more complex that necessary. We will focus on the following classifications:
        • Combination
        • Decomposition
        • Single Replacement
        • Double Replacement
        • Combustion
      • For the exam, you may be asked to classify reactions, balance chemical equations, predict states of reactants or products, and predict the solubility of ionic compounds. However, you will not be asked to predict the products of reactions on this exam, or to write net ionic equations (those will be covered on Exam #4).

    • In addition to the Sapling Problem Sets, preparation for the exam should include working problems assigned from the chapters above (5-8), and the extra practice problems below:

    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! Lab does not meet on Wednesday, August 17, but I will be in the lab part of the afternoon.
  • Waitlisted students: Attend LECTURE on the first day of classes, Wednesday, August 17 and the LABORATORY class you wish to enroll in on Monday, August 22 or Wednesday, August 24. Add codes will be offered in lab sections NEXT WEEK (AA section on 8/22 and AB section on 8/24).
    • If you are interested in enrolling in either lab section, please come to the start of both next week; however, you are required to stay for the whole session only once. If you are not able to attend both next week, please email me individually before then.

  • 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

    • 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.
      • It is a math review set that requires only knowledge through Introductory Algebra (a prerequisite for the course), so you can get started on this right away.
      • For this problem set, you have UNLIMITED attempts to answer each question with NO POINT DEDUCTION.
  • Course Notes Outlines are posted on the LECTURE page. We will use the first few sets during lecture and lab during the first two week of classes. There are files better for viewing on computers or other electronic devices and others intended for printing. Choose the format that is best 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.
