A total of 1000 points are possible as indicated below:

  • Final (comprehensive), 200 points
  • Exams (2, 150 points each), 300 points
  • Quizzes (4, 50 points each),  200 points
  • Lab Experiments (normalized total), 300 points

Course grades* will be assigned according to the following breakdown:

A 88.0-100%        B 76.0-87.9%       C 60.0-75.9%       D 50.0-59.9%       F less than 50%

*LACC does not have a +/– grading system.  Only A, B, C, D, F, I**, W, P/NP will be used.  I do not curve grade.

**Incomplete academic work for unforeseeable emergency and justifiable reasons at the end of the term may result in an “I” symbol being entered in a student’s record.  The “I” must be made up no later than one year following the end of the term in which it was assigned.  The policies can be found here.  Further more, the following will be applied.  You must currently be passing the course for an incomplete.  You must satisfactorily complete 7 out of the 7 laboratory assignments.  A score of “0” will be recorded for any unfinished assignments and can not be made up.  You must have completed all exams and 3 out of 4 quizzes. A score of “0” will be recorded for the 4th quiz and can not be made up. The final must be taken within a year and a letter grade will be recorded after its completion. Do not assume you will be granted an incomplete without consulting with me first. 

Student Learning Outcome: The student analyzes, provides the steps to solution, and solves given problems from a variety of chemical systems and situations including kinetics, equilibrium, thermodynamics and electrochemistry. The student will perform proper laboratory skills and techniques exhibited in second semester chemistry potentiometric titration laboratory experiment, demonstrate correct analysis of data, and graphing skills.

Financial Aid:  If you need help paying for books and other college expenses, call the Financial Aid Office at (323) 953-4000 ext.2010.

Information for Students with Disabilities: Students with a verified disability who may need authorized accommodation(s) for this class are encouraged to notify the instructor and the Office of Special Services (SSV 100, 323-953-4000, ext. 2270) as soon as possible.  All information will remain confidential.

Audio/video recording is not permitted unless accommodation letter states otherwise.

Academic Integrity: All students at LACC are expected to follow the rules of ethical conduct stated in the Student Policies section of the Schedule of Classes.  The complete schedule of classes in PDF format is found here.

Cheating will not be tolerated!  Violations of academic integrity include, but are not limited to, the following actions: cheating on an exam, plagiarism (the act of copying another’s written work and submitting it as your own), faking or falsifying experimental data, copying another’s lab report, data, and published work, working together on an assignment, paper or project when the instructor has specifically stated students should not do so, submitting the same term paper to more than one instructor, or allowing another individual to assume one’s identity for the purpose of enhancing one’s grade (see LACCD Board Rule 9803.28). Such actions (which are often illegal in the “real world”) may result in a grade of zero on an exam or paper, and suspension or dismissal from the course and the college. These consequences will also apply to those that help others cheat.  

Drop Date Information!  For classes from 2/6/17 to 6/5/17, the deadline to drop without a “W” on your transcript is Monday, February 20, 2017. Effective July 1, 2012 students are allowed three (3) attempts to pass a single class within the Los Angeles Community College District. If a student gets a “W” or grade of “D”, “F”, or “NP” in a class, that counts as an attempt. If you think you will not be able to complete this course with a C or better, drop by Sunday, May 7, 2017. If the class begins or ends on a different date, please refer to Admissions Important Dates page. If you have any questions, please don’t hesitate to talk to me.  You may also see a counselor in the Counseling Center in AD 108. 

You will be excluded (dropped) from the course for any one of the following:  If you missed the first meeting of class, if you are absent more hours than the number of hours the class meets per week, or if you do not enroll in Canvas. However, you should not assume that the instructor will drop you. It is your responsibility to formally withdraw from the class through Admissions and Records should you decide you no longer wish to be enrolled, otherwise you will receive an “F” in the course. I do not exclude students once they have attended class and have turned in assignments. If you are absent, it is your responsibility to make sure work is handed in on time and to find out what you missed in class.

Computer Resources: The Chemistry and Earth Sciences Department has a computer classroom located in SCI 316.  The classroom is normally open 8:00 AM – 10:00 PM Monday-Thursday.  If the room is locked, you can ask one of the faculty or lab technicians to open it for you.  This classroom can be reserved for class meetings by department faculty.  If the classroom is unavailable, the all-campus computer lab for student use is located on the second floor of the Martin Luther King Library and is available during the library’s normal business hours.  Please contact ext. 2396 for more information about the all-campus lab.  For information about computer access, including information regarding computer login, email accounts and wireless access, please go to the following site.

Policy on Cell Phones and other Electronic Devices:  The use of cell phones or any other electronic devices for any purpose, including smart phone calculator apps, on exams/quizzes is prohibited.  All phones are to be turned off during exams and stored.  Students caught using phones during exam may be subject to receiving a score of “0” on the exam/quiz and referral for further disciplinary action.

Description of Coursework

Final: Everyone, regardless of grade at the time, is required to take the final examination. The date is listed in the schedule below. Failure to take the final will result in an automatic fail for this course, regardless of your grade prior to the final. The final will not be returned to you. Your score will be posted in Canvas.

Exams: Two exams will be given and no scores will be dropped. The dates are listed in the schedule below. The exam starts at the beginning of lecture and if you are late to an exam, you will have the remainder of that time to complete your exam. A penalty of 10% (per day-weekend counts) will be assessed for the first exam taken late, and a larger penalty (20% per day) for any additional exams taken late. Once an exam has been returned and reviewed (2-7 days), there will be no more make-up exams. It is your responsibility to re-schedule your exam, not your instructor’s. Send an email and I will confirm the date, time, and location of your make-up exam. If you do not show up, a score of “0” will be recorded and no further make-up will be allowed.

Quizzes: Four quizzes will be given and no scores will be dropped.  The dates are listed in the schedule below. There are no make up.  Each quiz starts at the beginning of class and if you are late, you will have the remainder of that time to complete your quiz.

Laboratory work: The laboratory component is designed to give you hands-on experience with some of the concepts learned in lecture. All laboratory experiments and reports are done independently by each individual. There will be no makeup labs. You must satisfactorily complete all laboratory assignments in order to achieve a grade of “C” or higher, regardless of total score.  Completing lab consists of performing the experiment and handing in the lab report.  Typed lab reports are due one week from the date the experiment is completed.  There is a 20% penalty for each day that your report is late (weekend counts).  After a report has been graded and returned, you will only receive one point for that assignment, but it counts as being completed.  All chemical structures in lab reports and presentations must be electronically drawn, no hand-written insertions.  ChemDraw is installed on the department’s computers.  Please schedule time to learn the software and to use it at LACC if necessary. No points will be credited to one student for lab work completed by another student; that is cheating.  

Safety goggles are to be worn by all students in the laboratory at all times.  Students who repeatedly are found not wearing goggles (to protect their eyes) will be subject to removal from the laboratory for that entire period.  

You are responsible for all of the equipment in your locker. You will lose two points for each equipment you break or lose. It is best not to share equipment, and if you absolutely must share, be sure to return any shared equipment to your locker before you leave for the day.  Make sure you have put away all equipment and locked your drawer before leaving.  

All students are required to keep a lab notebook. The notebook must have carbonless duplicates. You are required to prepare your notebook for data collection prior to coming to class. You will record all data directly in your notebook and you will turn in the carbon copies of your data sheets. Notebook policies are described in more detail here

You are responsible for printing out your experiments prior to coming to lab.  I will not print them for you.

For each minute you stay after lab is over, you will lose two points. Please set a timer so that you have enough time to clean up. Everyone is responsible for cleaning up the lab.

 Canvas is mandatory. Please learn to login and check your announcements weekly!  This program serves as my course management system.  Graded and returned work are your responsibility. 

Mastering Chemistry (MC): The homework is graded through the Mastering Chemistry web-based program. The MC assignments include interactive tutorial assignments and electronic versions of selected end of chapter problems from your text.  There is a correlation between doing problems, understanding the course material, and doing well on exams.  The more problems you make an honest effort at completing, better are your chances of doing well on the exams.  The point of doing MC is to improve your understanding of the material, not to practice for exams.  Exam problems do not necessarily look exactly like homework problems.  However, if you truly understand the material, then you should be able to reason through exam problems that look different from homework problems.  

If you purchased the LACC version of the textbook for Chem 101, you already have the access code for Mastering Chemistry.  Copy and paste the course ID and type in the access code.  If you did not purchase the LACC version, you may purchase an access code.  Select the correct text for your course and select the choice without the e-text.  As of 8/1/2016 the cost is $65.95 without the e-text.

Study Guides for Exams and Extra Credit:  There are none, please don’t ask.  There are old exams & quizzes are under the “Exams” tab (still under construction).

Miscellaneous: Please don’t ask for an extension on assignments. Natural disasters are not excuses for not completing your work. The last day to turn in late work (for one point) is before the start of your final.
