Course Objectives: Chemistry 1A is am advanced course in chemistry designed not only for chemistry majors, but also for biology, physics, chemical engineering, pre-medical and pre-pharmacy majors.  As a prerequisite students need to have passed CHEM10, or High School chemistry, with at least a C grade as well as basic algebra (Math 103). If you have never taken chemistry before, or it was a long time ago, I would suggest you take CHEM3A rather than CHEM1A.

 

Textbook:  Nivaldo J. Tro: Chemistry: A Molecular Approach 2nd Edition (same as Fresno City College). A softcover, customized version of this book is available at our bookstore with just the first half of the book that will be used in CHEM1A. (A softcover version of the second half of the book is also available for CHEM1B).  If you have a 1st edition I will give you the alternative homework numbers, but you will not be able to sell your book easily.

 

Lab Manual: Dekker: Quantitative and Qualitative Laboratory Experiments BOOK A  (not BOOK B)

Other Supplies: A calculator is required (needs exponents and logs, but not a programmable calculator).  Approved safety goggles and lab coat.

 

Lecture Notes: Download from my Blackboard website prior to class and fill in the notes during class. Homework is assigned at the end of the notes and is due the next lecture period. Studies have shown that 90% of the lecture material is retained if you review the lecture within 24 hours.

 

Homework: Homework will be assigned every lecture, collected at the beginning of the following lecture and a few problems graded. Show all your work, not just the answers.  It is essential to your success in this class that you do all the assigned homework and read the relevant sections in your textbook. This is to ensure that you work consistently and can apply what you learn to problems. There will be no make-up homework assignments, but I will drop the lowest two homework assignments. Do not copy somebody else’s homework. You only learn by doing the homework problems for yourself. You can ask another student or tutor to help you with some problems, but you need to work them out for yourself. If two students hand in identical homework, I will deduct points from both students! Even if you get all the problems wrong, you will still get 70% for the assignment for attempting all the problems yourself, and you will learn where you are going wrong when I go over the homework. If you can’t attend the lecture, give your homework to me or to switchboard prior to the class period they are due.  I will accept late homework at the beginning of the following lecture period, until I start handing back that assignment.  10% will be deducted for late homework assignments (no matter what your excuse). If you come into class late, turn in your homework at the front desk as you walk in.

 

Attendance: Attendance in lectures and lab is mandatory. The student will be dropped automatically if she/he misses 2 weeks without contacting the instructor. If you miss a lecture you need to obtain the notes to fill in from another student and read the section in the textbook before meeting with the instructor/tutor to discuss any problems. As an incentive to attend lectures, an additional two homework assignments will be dropped at the end of the semester if a student attends 90% of the lectures. If a student is disruptive (including using cell-phones, talking, interrupting the instructor continuously) they may be asked to leave the lecture/lab and recorded as "absent".

 

Absences from Labs and Exams There will be no make-up labs or exams. I will drop one missed lab and any subsequent missed lab will be graded with a zero. If you miss an exam the final exam grade will count for that missing exam too.

 

Drop Date: The last day to drop this class is Friday March 11, 2011. After this date a grade will be assigned.

Change to Pass/No Pass: The last day to make this change is Friday, February 11, 2011

Martin Luther King Jr. Day: Monday, January 17. No classes held

Lincoln Day: Friday, February 18. No classes held

Washington Day: Monday, February 21. No classes held

Spring Break: April 18-22

Final Exam Date: Monday, May 16, 9:00-10:50.

 

Grading : There will be 5 lecture exams, equally weighted and counting towards 65% of your grade. The final exam will be cumulative and multiple choice. Homework will count 10% and your lab work will count 25% (12.5% lab reports and 12.5% lab quizzes)

Grading: A 90-100%, B 80-89%, C 70-79%, D 60-69%, F 0-59%

 

Tutoring: Free tutoring is available at the Tutorial Center at the Library

 

Please be aware of the following rules:

  • Tardiness, leaving early, or sleeping during lectures will result in a partial or full absence being recorded. Students need to sign the sign-in sheet within the first 10 minutes of class.
  • Fraudulent behavior during exams is graded with a (0) zero.
  • Copying of homework, experimental data, and lab reports is considered fraudulent behavior for both the copier and the originator. DO NOT HAND IN IDENTICAL HOMEWORK.
  • No homework may be handed in after I have started handing it back.  No alternative homework will be given. I will drop the lowest two homework assignments though, four if your attendance is 90%.
  • No extra credit will be given. You need to work consistently from the beginning.
  • Please turn your cell phones onto “silent buzzer” mode during lectures so as not to disturb the class. No cell phones or i-pods will be allowed during exams.

 

LABS

  • Read the lab write a title and summary of the procedure before coming to the lab. These will be checked at the beginning of the lab. Be on time or loose the points for this summary.
  • Safety glasses need to be worn whenever somebody near you is conducting an experiment.
  • No experiments may be conducted without the instructor or teaching assistant present
  • No horseplay or unauthorized experiments. Do not taste any chemical or smell any chemical directly.
  • Dangerous behavior in the lab will result in the student being asked to leave the lab.
  • No visitors inside the lab. You need to go outside to meet with them.
  • No food or drinks allowed.
  • Backpacks should not be left on the floor where others can trip over them.
  • Closed shoes and lab coats must be worn in the lab at all times.
  • Long hair should be tied back so it will not fall into chemicals or flames.
  • If any accident occurs in the lab, inform your instructor and follow safety procedures. (To be discussed during first lab period)
  • Clean up any spills promptly (Clean-up procedures will be discussed during first lab period)
  • Do not point the open end of a test tube towards anybody
  • Turn off flames when working with organic solvents. Dispose of them in waste bottles in the fume hood, not down the sink.
  • At the beginning of each lab your instructor will inform you of any special safety precautions and how to dispose of used chemicals. You need to be on time for the lab so that you hear these instructions.
  • Do not dispose of matches, paper or solid chemicals in the sink. Use the large evaporating dishes or sand bucket for spent matches.
  • Put broken glassware in the “broken glassware box”, not in the trash.
  • Before leaving the lab, wipe the desktop and wash your hands with soap and water.

 

If you have a verified need for an academic accommodation (especially in labs) or materials in alternate media (i.e., Braille, large print, electronic text, etc.) per the Americans with Disabilities Act (ADA) or Section 504 of the Rehabilitation Act, please contact me as soon as possible.
