Course Information:

 

Chemistry 111A is the first part of a one year general chemistry lecture-laboratory course intended primarily for science, engineering and pre-professional students.

 

Prerequisites:

 

A grade of "C" or better in Chem 107 or a passing grade in the ACS Diagnostic Test; completion of Math 40 Intermediate Algebra; or equivalent with grade of "C" or better.

 

Reading Assignments and Homework:

 

Keep up in your work and do the reading assignments before coming to the lecture covering that topic.  If your textbook is not clear on some topics refer to other textbooks.  Additional textbooks will be on reserve in the limited loan section of the library.  Your success in this course will be based to a large extent on how well you grasped important principles and how well you are able to solve problems.  Therefore, it is important you keep up with the assigned problems.  Turn in your homework to your instructor and selected problems will be graded.  In solving the problems, make sure that the methods by which you arrive at your answers can be clearly followed.

 

Tutorial Resources:

 

The tutorial center is open Monday to Friday to assist students.  In addition to this, an on-line resource center is available to enhance the learning of general chemistry based on your textbook.  Students need to purchase an ID card to have access to on-line resources and other computer programs and software.  The website (http:\\www.smarthinking.com/houghton.html) has various features -tutorials, interactive problem-solving center and quizzes.  For problem solving sessions, we will often use the internet to go to a modular called Mastering Chemistry (http://titanium. fullerton. edu)

There are no make-up exams.  Any missed exam is considered a dropped exam, regardless of the reasons.  A student planning to miss a second exam for serious reasons must consult with the instructor.  The instructor may decide to give more exams, unannounced quizzes or any other assignments when deemed necessary.  The instructor may also change the exam dates and due dates for various assignments.  Everyone has to take the final exam. The exams could be in the form of multiple choice questions or essays or calculations or any combination of all these formats.  Students should bring calculators, pens, pencils (#2) and scantrons (#882).  Wide window calculators, or calculators capable of storing text, are not allowed during exams or quizzes. Students have to participate in group activities in both lecture and problem solving sessions.  Turning laboratory/activity reports for missed sessions is considered cheating.

 

If the instructor, due to unforeseen emergencies, does not arrive at the scheduled start time for class, students are to remain in class for fifteen minutes, (unless otherwise notified by the division).  If you do not receive notification to wait for your instructor to arrive, you may leave after fifteen minutes, with no penalty for absence or assigned work due for that class meeting.

 

Withdrawals and Incompletes:

 

If you are considering to withdraw from the course, consult with your instructor first.  Also, be sure you understand the college's policies on withdrawals and incompletes (refer to class schedule for the semester).  The instructor hopes that no student will have to withdraw from the course.  A student withdrawing from the course  must first check-out of the lab lockers.

 

STUDENTS ARE TO BE AWARE OF AND ABIDE BY THE COLLEGE'S REGULATIONS

CONCERNING STUDENT CONDUCT.  A POLICY GUIDELINE ON ACADEMIC HONESTY IS ATTACHED.

 

CHEMISTRY 111A LABORATORY (CHEM 111AL)

Instructor:                                 Dr. Tilahun Yimenu

Office:                                      2023-R4

Telephone:                                (714) 992-7442, Email:  tyimenu@fullcoll.edu

Office Hours:                            T Th 11-12:30 p.m., T Th  5:30-6:00 p.m., M W 12:45-1:30 p.m.

 

Required Supplies:                    Case hardened safety goggles

Calculator with logarithm and exponential notation functions

Laboratory:

In Chemistry 111A, the laboratory is an integral part of the course.  Failure to complete the experiments and hand in the reports will result in unsatisfactory grade for the course.  Laboratory reports should be written in ink and should be stapled together.  White-outs should not be used on lab reports.  The report is due at the beginning of the next laboratory period.  Late reports will lose 25% of the value of the experiment (excepting excused late reports).  Students have to participate in group activities and problem solving sessions.  For problem solving sessions, you will do group exercises and utilize the Internet (Room 434 or 412) to access a modular called Mastering Chemistry (http://titanium.fullerton.edu)  Turning in laboratory/activity reports for missed sessions is considered cheating.  Your laboratory grades are based on your lab reports, problem solving activities and the lab practical.

 

Laboratory Safety Procedures (SHP)

Safety must be a primary consideration for all persons entering a chemical laboratory.  Experiments have been selected for their relevance to the lecture class materials as well as their expected safety for students learning new techniques.  Students have the responsibility for learning and understanding appropriate safety instructions for each experiment.  Further, each student has an obligation to consult the instructor for help when safety procedures are not clear.  The following general procedures must be observed.  Also read the 21-point safety instructions and the emergency response message attached with this syllabus.

 

1.         Before beginning the first experiment, familiarize yourself with the location of the fire extinguishers, safety shower and eye wash fountain in the laboratory.  consult with your instructor regarding the proper operation of this equipment.  Also, read the information on laboratory safety which can be found in the text.  Always note any safety precautions which are mentioned for specific experiments.

 

2.         Approved safety goggles must be worn at all times while you or others are working in the laboratory.

 

3.         Wear appropriate clothing. This includes closed-toe shoes and some type of protective apron or lab coat.

 

4.         Work is not permitted in the laboratory except during regular class periods when an instructor is present.  Performance of unauthorized experiments is not allowed.

 

                        5.         Smoking, eating and drinking are not permitted at any time in the laboratory.

 

 

6.         Waste chemicals must not be poured down the drain without proper treatment or neutralization.  Consult your instructor before excess chemicals are disposed of.

 

                        7.         Report any accident, even the most minor, to your laboratory instructor.

In case of a chemical splash, flush the area thoroughly with water.  Use the eye wash for at least 15 minutes for chemicals in the eyes.  Fires can usually be extinguished by smothering.  Use the fire extinguisher with care.

 

8.                  Please read the 23-point Laboratory Safety Recommendations in the Lab. Safety Packet.

 

9.                  If you miss the first day laboratory session, you must watch the safety video online before you come to the next lab meeting. The website is at http://www.oid.ucla.edu/webcast/chemistry/chemistry body.html

 

Withdrawals and Incompletes:

 

If you are considering to withdraw from the course, consult with your instructor first.  Also be sure you understand the college's policies on withdrawals and incompletes (refer to class schedule for the semester).  A student withdrawing from the course must first check-out of the lab lockers.

 

 

Student Wait Time for Instructor

If the instructor, due to unforeseen emergencies, does not arrive at the schedule start time for class, students are to remain in class for fifteen minutes, unless otherwise notified by the division.  If you do not receive notification to wait for your instructor to arrive, you may leave after fifteen minutes with no penalty for absence or assigned work due for that class.
