CHEM 102 - Introductory University Chemistry II

Chemistry is the study of the enormous variety of materials of the universe and the changes that these materials undergo when they interact with each other. One of the joys of learning chemistry is seeing how chemical principles operate in all aspects of our lives, from everyday activities such as lighting a match to more far-reaching matters such as the control of acid rain. Hundreds of materials that are currently in use are products of chemical research. For example, development of pharmaceuticals, plastics (nylon, Teflon, polyester, silicone, etc.), fertilizers, computer chips, steel, paper, and wood products are all results of chemical studies.

Conduct of Course:
This is a 3-credit course with 3 hours of lecture and 3 hours of lab per week. (3-0-3).

Chemistry 102 students attend lectures, participate in discussions, and run experiments in the laboratory. The class meets for a total of three hours (lecture/discussion) per week. An additional hour may be scheduled if necessary. The class also meets once a week for a three-hour laboratory and computer assisted learning session. The instructor uses transparencies, videos, and computers as educational aids.

Students are assigned problem sets and are also asked to do end-of-chapter questions as homework. The aim is to give students more practice to enhance their skills in problem solving that is so essential to doing well in this course. The results contribute to the final grade. In this regard, the Solutions Guide can also be of real benefit to the student. It provides detailed solutions for two-thirds of the end-of-chapter exercises using the strategies emphasized in the text. If interested, students can purchase their own copy of the Solutions Guide from the bookstore.

Laboratory

The laboratory sessions are once a week (3 hours). Students are required to study the “theoretical considerations” of every experiment before coming to the lab and may do a lab quiz at the start of the lab period. The “Prelab Assignment” is to be done and turned in before students start each lab. The “Prelab Assignment” is designed to help students understand the experiment and to give them step-by-step practice with calculations. Marks are given for its completion.

For every experiment there are two observation sheets and a report form (see the lab manual for each experiment B. The two observation sheets are to be filled out as students are doing the experiments and they should be handed in at the end of the laboratory period, before leaving the lab. The lab report should be completed and turned into the instructor within two days of completion of the experiment. For example, a lab that is done on Monday must be turned in by Wednesday before 4:30 pm.

There is a brief lecture (approximately 10 minutes) on experiments that need theoretical background not covered in the lectures because synchronizing lectures with labs has always been a problem in chemistry courses and very often lectures and labs do not correlate with one another. This is because it is often not possible to match the pace of lectures to topic changes in the lab.

In order to eliminate accidents in the laboratory, students are required to read and obey the rules of safety outlined in the manual. The chemistry laboratory is a potentially dangerous place if students fail to observe safety precautions. Every student must acquire a pair of safety glasses (available at the bookstore at a minimal price). Contact lenses are not a substitute for safety glasses and are particularly dangerous if a chemical gets in the eye. Prescription glasses are acceptable if used with side guards.

Federal and Provincial Legislation (WHMIS) recognizes the workers “right” to know about hazardous materials in the workplace. Students carrying out experiments in a lab are considered workers, and the lab is their workplace. Therefore, they need to identify dangerous chemicals in the lab and be able to protect themselves. The required information is provided in what is called Material Safety Data Sheets (MSDS). Students are requested to consult the MSDS before running an experiment. Materials Safety Data Sheets (MSDS) of all chemicals used in the Lloydminster campus chemistry lab can be found in two locations:

1.One set is available in the library. Students can find them in the reference books section or ask the librarian for help.

2.The other set is in the Hazard Information Center in Room 1008 (chemistry lab).

Laboratory Schedule

The labs begin a week after classes start. There are eight experiments and one lab exam as listed in the Course Units/Calendar section of this outline. These follow the same sequence as found in your lab manual.

Students are expected to attend all lectures and laboratories. If more than four lectures are missed, except for extenuating circumstances, the student is not allowed to write the final examination. Missing even one lab without legitimate excuse results in a failing grade in the course regardless of exam marks.
