Website: http//faculty.coppin.edu COURSE DESCRIPTION: CHEMISTRY 103- Chemistry for Health Sciences A systematic study of the basic principles, laws and theories of modern chemistry. General topics covered are: measurement, atomic structure, formula names, periodic table of elements, chemical equations, chemical calculations, chemical bonding, stoichiometry, energy and chemical reactions. Any mathematical skill needed beyond MATH 100 will be developed as part of this course. This course is similar but identical to CHEM. 101. It is designed primarily for nursing majors and deals less with theoretical chemistry but more with the practical applications in health professions. Prerequisites for this course are MATH 101, Math 125 or CHEM 100. (3 hours of lecture and 3 hours of lab per week.

EXAMINATIONS, COURSE GRADING, COURSE STRUCTURE Course Grading

Your final course grade will be computed as follows: Best Four [3] out of Four(4) lecture exams @ 20% 60% Final comprehensive examination 20% Laboratory Reports and Exercises 20%

The correlation between letter grades and numerical grades on exams will be: 2

A = 90-100%; B = 80-89%; C = 70-79%; D = 60-69%; F = 0-59%

A total of four lecture examinations will be given during the semester, and the lowest grade of these will be dropped. The grade obtained on the final comprehensive examination will not be dropped. The examinations will be given at the beginning of the lab lecture period or during class time. The approximate schedule for the lecture examinations will be announced one week in advance before they are given. Attendance is required for all examinations and laboratory work. You must pass both the lecture and laboratory with a grade of D or better to pass the course. If you fail either lecture or laboratory, your final grade will be an F. No make-up examinations will be given. A missed examination automatically becomes the score that is dropped. STUDY HINTS FOR CHEM. 103

A few comments and study hints are provided here, with the hope that some of them may be beneficial.

General chemistry has the reputation of being a very hard course, requiring a lot of memorization but in reality, it is not if you have a very good study habit. As you will soon see, a reasonable amount of memorization is required in general chemistry, though much of it is rather systematic. Most students are often overwhelmed by the number of reactions, and mathematical skills that confront them; they often wonder whether they can learn this material in a single semester. This course is designed to help students develop thinking skills that are needed to study general chemistry. These skills include mathematical skills such as proportional reasoning as well as skills to reason at the abstract level since most of the fundamental concepts are abstract. In order to develop these Scientific reasoning skills, the course content is presented in a three part sequence. The first part involves observation of scientific phenomena. The second part involves the introduction of terms and the development of the concepts in the scientific phenomena. The third part involves the applications of the concepts just developed with the hope of developing a better thinking skills and a better appreciation of the filed of chemistry. My lectures are intended to emphasize and summarize important principles and concepts from the text. They will parallel the text, with most examples given being different from those in the text. This course will challenge your organizational skills. Be forewarned that it is not possible to succeed in a General Chemistry course like CHEM. 103 without a good study habit. The bulk of the material we will study this semester will involve mathematical calculations, development of concepts and reasoning, conversions factors, chemical equations and stoichiometric relationships. Thus it is highly important that you develop good study habits in learning these concepts during the entire semester..

The best method of studying general chemistry will vary from student to student, and I offer the following study hints and suggestions with the hope you will find one or more of them beneficial. 1. Lecture Notes. It helps to recopy your lecture notes the same day as the lecture. This gives you the chance to review the material again while it is fresh in your mind and to add material that you might not have copied down. This can be very helpful if done in conjunction with the assigned reading material in the text.

2. Reading Assignments. Reading assignments for the entire semester are provided in the syllabus. You will get more from the lectures if you read, or at least scan, the assigned material before coming to class.

3. Study Problems. A number of study questions have been assigned from the text, and these represent the minimum number of problems you should solve. Work the problems on your first, but only after you have studied the material well. A major key to success in organic chemistry is working study problems. Try to work a couple of problems each day and not let them pile up just before an examination. Again, the key or secret to success in general chemistry is continual and systematic study. Most students (good students) will agree that general chemistry is not intrinsically hard, but it requires a great deal of work.

4. Learn and study Concepts in General Chemistry by the use of flash cards. The use of flash cards is highly recommended as a device for learning reactions, equations conversion factors, etc. Work as many of the assigned study problems as you can. If approached properly, these provide a good self-test of the material and serve to give you confidence that you have mastered the material. Keep Up, don't fall behind. Continual study and continual work on study problems is very important. You are not required to hand in any of the assigned study problems, but you should work each of them because some of the assigned study questions will appear on each examinations given during the semester. 3

My lectures will primarily cover the information found in the text and in some cases the information that are important and not found in the text. Some previous examination that I have given in General Chemistry 101 which are very similar to CHEM. 103 are found at my website: http://faculty.coppin.edu.

5. GENERAL COURSE GOALS:

1. Introduce the students to the concepts and principles of chemistry

2. Develop the verbal and mathematical skills of the students so that they may accurately interpret and solve chemical problems

3. To prepare the students for more advanced courses in chemistry

4. To help students to develop thinking skills that are used in chemistry

6. BEHAVIORAL OBJECTIVES:

1. At the end of this course, the student should be able to answer fundamental questions pertaining to chemistry correctly.

2. At the end of this course, the student should be able to solve simple chemical problems;

3. At the end of this course, the student will be able to notice the difference between an orbit and an orbital, shell and sub-shell, atomic numbers and atomic weights, orbital shape and orbital orientation, thermochemistry and stiochiometric relationships.

Any missed work must be completed and will be accepted only after evidence of appropriate excuse for missing class. As indicated above, a missed exam automatically becomes the one to be dropped.
