Announcements & Important Course Information
Wednesday, March 4
Tuesday, March 3
Monday, March 2
- The Experiment #5 handout (updated for the current semester) is available on the LABORATORY page. Please have access to it during lab on Tuesday.
- PS #5 (due Mar. 9 at 9pm) and PS #6 (due Mar. 11 at 9pm) are now posted.
- This was originally intended to be one PS that I have split into two; however, each will be worth the full 6 points.
- Equilibrium 1,2,3, & 5 answers are now posted.
Wednesday, February 25
- As announced in lecture, you may submit the Experiment #3 Report up until 1pm on Friday. You may turn in in class or to me in my office anytime before then also. If I am not in my office, you are welcome to slide it under my door. (The custodians know I receive papers this way and they will leave them there for me.)
- Tomorrow in lab, we will begin with the Day 2 titrations (or for those of you who need to prepare the experiment again, you will have that opportunity). Approximately one hour will be allotted to work with the chemicals and to perform your calculations. After that we wil be moving on to other topics and the laboratory equipment and chemicals will no longer be available to use for the session.
Friday, February 20
- New equilibrium powerpoint notes outlines are posted on the LECTURE page.
- If you have not already, please begin reading and working book problems in Chapter 17 - Chemical Equilibrium.
Friday, February 13
- Reminder: If the percentage you earn on Exam #1 is better than your quiz percentage, the two percentages will be averaged and your Quiz #1 score will be replaced with that percentage of 30 points. This will help to mitigate a poor performance on Quiz #1.
- Problem Set #3 Notes on Sapling Learning:
- You do not need to answer question #12. It is more complex than we have studied.
- However, if you interpret the question with the second step as the slow step, then you can treat it like questions we have studied and apply the SSA.
- I will NOT include this question in the final grading analysis.
- You are not required to answer question #17. We have yet to cover the material for it.
- However, considering the equilibrium and the reaction quotient (we will cover this on Wednesday) along with a stoichiometry table for equilibrium, you likely can still answer it.
- I will NOT include this question in the final grading analysis.
- A similar question will be included on the next problem set for credit.
Sunday, February 8
- Experiment #2 Prelab Question #1:
- Many students missed all of the points on the Experiment #2 Prelab Question #1 (the graphing problem).
- Those students who made significant errors in the question will be offered their prelab assignment back tomorrow (Monday) in lecture to revise for partial credit. If you are already sure that you did not make the proper graph for the question or did not interpret it correctly, you are of course welcome to begin reworking it now. I recommend revising and resubmitting before you leave campus on Monday. The revised prelab must be turned in before the start of your registered lab session on Tuesday. I will be available to answer questions during office hours.
- As will be the case with other assignments in the course turned in outside of class time, you may turn in to me in my office. If I am not in my office, you are welcome to slide it under my door. (The custodians know I receive papers this way and they will leave them there for me.)
- Important notes: The revised prelab must be turned in before the start of your registered lab session on Tuesday. Once the lab begins, students who have not resubmitted their prelab will earn their original score. Students offered the option to resubmit who do not claim their prelab on Monday or do not resubmit will still earn their original score.
- Please staple the revised prelab question #1 on top of your original prelab and put your name on it when resubmitting.
- Problem Set #3 is posted on Sapling Learning.
- Reminder: Quiz #1 will be administered at the start of your registered lab section on Tuesday, February 10.
- Please bring the Kinetcs 1 Follow-up worksheet, the lab handout on Standard Deviation and the lab handout for Experiment #3 to lab on Tuesday.
Wednesday, February 4
- Answer keys to Kinetics 1 and the Reaction Rates - Graphing worksheets are now posted on the lecture page.
Saturday, January 31
- Thank you to all of the students who helped out with the EYH mailing on Friday! It went very well and we managed to complete the work for the mailing!
- We will not NOT be holding a second mailing on Monday, February 2. However, there will be additional volunteer opportunites for EYH coming up, incluing the actual event on March 21.
- Problem Set #2 is now posted on the Sapling Learning Website. It will be due next
Saturday, February 7 at 6pm.
Tuesday, January 27
- EYH Spring Mailings - Your help is needed!
- EYH Spring Mailing #1 – Friday, January 30
- Room: 7-341 (CHEM LAB)
- Time: 1:15 ~ 3:30 pm
- Welcome to CHEM 220 - General Chemistry 2 for Science Majors. I am looking forward to a productive, challenging, and rewarding semester.
- Our first CHEM 220 class meeting will be LECTURE on January 23 at 10:10 am in 7-310.
- Our first LABORATORY sessions will be on Tuesday, January 27 at 9:20 am (AA section) and 2:10 pm (AB section) in 7-341.
- It is very important that you attend your first lab session on Tuesday, January 27 and continue to attend in order to maintain your registration and/or waitlist priority. In the first lab, we will discuss the lab portion of the syllabus, enrollment, and cover important safety information that is required to participate in the lab, and have our first lab lecture.
- Parking may be a challenge the first couple of weeks of classes, so I encourage you to arrive to campus early!
- Scroll down the page for more detailed enrollment & waitlist procedure information.
- Sign up for the Sapling Learning Online Homework System: https://www.saplinglearning.com/
- Follow the above link.
- If you have an account, log in. If you do not have an account, create an account.
- Please enter your first and last names in the profile as they appear on your official Skyline record. If you go by a different name or a nickname, please put it in parentheses after your first name.
- Select Skyline College.
- Select General Chemistry 2 - CHEM 220 - Bates.
- When you register for the course on the system, you will be able to use it for two weeks for free. You must then pay to continue to have access. This will give those students on the waiting list time to determine if they will be able to enroll in the course before purchasing.
- Problem Set #1 will be posted soon. It will be due Friday, January 30 at 6pm.
- If you would like to get started preparing for the semester, I recommend that you begin the reading and book problems (see LECTURE page) for Chapter 16 on Reaction Kinetics.
- The following worksheets are from the General Chemistry 1 course and cover topics that will be critical in all of our work this semester - Stoichiometry and Solutions. I recommend that you work these problems as review. A quiz early in the semester will cover these topics and some of our initial work in Kinetics.
- 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
- The prerequisite for CHEM 220 is:
- Successful completion (C or better) of CHEM 210 (General Chemistry 1) 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.
Important Enrollment & Waitlist Information
- As of 4 pm on January 20, the morning lab section is full with a waiting list, and the afternoon lab section has 2 openings. We will do our best to accommodate students, but it is possible that not everyone on the waiting list will be able to register for the class.
- Continue to follow standard WEBSMART registration procedures and check your my.smccd.edu email account for WebSMART notifications up to the first day of CHEM 220 class - January 23.
- Attend LECTURE on January 23 and LABORATORY on January 27. You must attend one of the two lab sections on that day to maintain your enrollment in the course and/or your waitlist priority. If there is an unavoidable reason that you must miss during the first lab day, please contact A.J. Bates in advance.
- Waitlist priority will be observed for each lab section separately. If you are interested in more than one section, or wish to enroll in a different section, you must add yourself to the waitlist for that section.
- Starting with the first day of classes:
- If you are enrolled
in the course section you wish to attend:
- You are ready to go! Plan to attend the first lecture class on January 23 and the first laboratory class on January 27. Attendance at lab is always required; however, it is particularly important that you continue to attend your scheduled
lab classes during the first two weeks, or you risk being dropped from
the course to make room for waitlisted students.
- If you are waitlisted for a course section:
- You are required to attend one of the two scheduled labs on January 27 in order to maintain your waitlist priority.
- You need only attend one of the two sections on that day. I recommend attending your prefered section.
- If you are enrolled in one course section, but are waitlisted for another, you may attend either section of the of lab on January 27. As long as you attend one of the labs, you will maintain your place in your enrolled section until you register in another (if a spot in your preferred section becomes available).
- If you are unable to enroll in your preferred section and you are unable to add to the waitlist for it prior to January 23:
- Add your name to the waitlist sheets for the course section(s) you wish to add to on January 23 during the LECTURE or January 27 in the LABORATORY.
- Your priority will be after all those who waitlisted prior to the first day of classes.
- Your priority will be the same as other students added to the waitlist on January 23-27.
- If necessary, a lottery will determine relative priorites of students added to the waitlist on those dates.
- Follow the same procedures (above) as all other students waitlisted for the course.
- After January 27, if
you are still waitlisted for your desired
- You must continue to attend a lab section as instructed in order to maintain your waitlist priority. Add codes may be provided in lab. If you are not in class (or late) your add code may be offered to another student.
- You must also attend lecture classes until you are able to add (or until it is announced that no additional adds will occur), as add codes may be provided in lecture. If you are not in class (or late) your add code may be offered to another student.
- You must check the course website (this page) and your my.smccd.edu email every day for important enrollment information. Information relevant to all waitlisted students will be posted on the course website. Individual information may be emailed.
- Please follow these instructions to maintain your waitlist priority. There are many students waiting to get into the course!
