A NURSE LIMNS CHEMISTRY

TABLE OF CONTENTS

Course Materials

CHEM-105 is a one-semester version of general chemistry designed specifically for students in the Department of Nursing. The required textbook is Introductory Chemistry: A Foundation, 4th ed., by Steven S. Zumdahl (Houghton Mifflin, 1999). Also required are a Complete Solutions Guide (4th ed.) to all problems in Zumdahl, by James F. Hall, and a Molecular Model Set. A Study Guide (4th ed.), by Donald DeCoste and Iris Stovall, designed to accompany the Zumdahl text, is an optional purchase. Students in CHEM-105 are presumed to be continuing with CHEM-106, Elementary Bioorganic Chemistry.

The Zumdahl text, which is written at a very basic level, was chosen with one primary goal in mind: to facilitate the learning of chemistry by students whose chemical background is weak or non-existent. Since the content of the course will, at times, go beyond the level of the textbook, additional study material will be provided in two forms: more advanced reading assignments (to be handed out separately), and a four-year file of past CHEM-105 examinations, complete with worked-out answers, in Section C.

Sixteen additional texts, each by a different author, have been placed on one-day reserve for CHEM-105 in the Reserve Room of Morris Library for your use should you need/desire an alternative to Zumdahl. The course content of CHEM-105/106 departs significantly from the first year chemistry course taken by nursing majors at many other colleges and universities. Instead of a full semester of general chemistry (CHEM-105), followed by a brief introduction to organic chemistry and a relatively extensive coverage of biochemistry (CHEM-106), these other year-long courses are roughly divided into equal thirds of general, organic, and biochemistry. Some of these sixteen additional texts follow this latter pattern, and are marked with an asterisk (*). The remainder are general chemistry texts that have been written at an even more basic level than the Zumdahl text. The texts in this latter group should be especially useful to students who did not take a chemistry course in high school or who are returning adult learners. You are strongly encouraged to use any or all of these texts if you perceive that you are encountering difficulty in mastering the CHEM-105 course material:

Your Teaching Assistant

A graduate teaching assistant (TA) will supervise your recitation section. If, in addition to these contact hours, you need help with the material, your TA will hold office hours for this purpose. Contact your TA directly to find out when and where his/her office hours are scheduled. A sheet showing the name, office location, telephone number, and E-mail address of the CHEM-105 TA will be distributed in class.

Exams and Grading   (Also see Absenteeism below.)

The course will be graded as follows:

Date		Weighting
Thursday, September 28	--	1st hourly  --  20 %
Thursday, November 1	--	2nd hourly  --  20 %
Thursday, November 29	--	3rd hourly  --  20 %
Weekly	--	Quizzes      --  20 %
To be announced	--	Final exam  --  20 %
		100 %

The three hourly exams will be given in class on the dates mentioned above and will test you on the material covered during the preceding month. Quizzes will be given during the recitation sections and will run 15-20 minutes in length. The quizzes will be announced and will cover the preceding week's material. The final exam will cover the entire semester and the date will be determined by the University later in the semester.

CHEM-105 course grades will be determined* as follows:

Course Grade	Required Performance Level (Over-all Average)
A	85 and above
A-	80 - 84
B+	77 - 79
B	73 - 76
B-	70 - 72
C+	64 - 69
C	56 - 63
C-	50 - 55
D+	47 - 49
D	43 - 46
D-	40 - 42
F	39 and below

*In 1999, the laboratory component of CHEM-105 was removed from the course, at the request of the Department of Nursing. The over-all averages were then normalized to eliminate the drop created by not having the relatively high lab averages included in the calculation. The extent of normalization depends upon the class's performance on the four exams (the better the performance, the larger will be the number of points added). In 1999 and 2000, this resulted in 5 points being added to each student's over-all average.

 

Help Sessions:

The instructor will hold a help session before each exam. Time and place will be announced in class.

 

Recitation Section

CHEM-105 includes recitation section meetings wherein the class is broken up into smaller groups. The purpose of the recitation section is to allow you to get your questions asked and answered in smaller groups. Weekly quizzes will be given and later discussed in recitation section. Assigned problems will also be discussed. However, you should work all of the assigned problems before coming to recitation section. Exams will be discussed in recitation section, but given at regularly scheduled lecture times.  There will be no make-up quizzes.

 

Tutoring

Our Department's Tutoring Service is managed by my assistant, Marian MacMillan (BRL 104, 831-2465,) marian@chem.udel.edu. She has prepared a list of available tutors for this semester. A supply of these lists has been placed outside the entrance of BRL 104. Additional copies are available in BRL 104. Since most of our UG and GR majors don't know that CHEM-105 exists, you should not hesitate to use the services of anyone who lists any of our general chemistry courses, i.e., CHEM-101/102, CHEM-103/104, CHEM-105, CHEM-111/112.

In addition, free small group tutoring is provided by the Academic Services Center in the George Evans House, 5 West Main Street (across from the Trabant Center),831-2805. To sign up: take your schedule to the George Evans House. The ASC will try to set up a group tutoring session for CHEM-105 to fit your schedule.

If you are contemplating the use of either a private tutor or group tutoring, the time to do it is NOW. Don't wait until after the first exam!

 

Absenteeism

It is a very rare student who does well in chemistry and regularly misses class. It would be advisable not to assume that you are this student. However, attendance in lecture and recitation sessions is your responsibility. No attendance records will be kept in lecture. An unexcused absence from a quiz or an exam will be graded ZERO. Everyone is expected to take the hour exams at the times scheduled above. Excuses for absences from exams or quizzes must be written. Acceptable excuses are:

1. Personal Illness (Note from Physician)
2. Death or Serious Illness in the Family (Note from Physician)
3. Court Attendance (Note from Clerk of Court)
4. Employment-related Conflicts (Note from Employer)
5. Official University Duties (Note from University Supervisor)

 

Lecture Notes

A copy of my CHEM-105 lecture notes for the past week will be placed on two-hour reserve in the Reserve Room of Morris Library for your use every Thursday afternoon, at the latest.

 

Videotapes of CHEM-105 Lectures

The videotapes of the CHEM-105 lectures that have been placed on reserve in Morris Library for your use were produced from my live CHEM-105 lectures during the 1989 fall term. The subject matter corresponding to each date in 1989 was as follows:

Date(s) (in 1989)	Topic(s) Covered
September 7	Course Orientation
September 12, 14	Nuclear Atom, Nuclear Chemistry, Mole Concept
September 19, 21	Electrons in Atoms, Periodic Table
September 26, 28	Electrons in Molecules and Ions: Chemical Bonding
October 3	Chemical Formulas, Oxidation Numbers, Nomenclature
October 4	Review Session for Examination I
October 10, 12	Chemical Equations, Stoichiometry, Gas Laws
October 17, 19	Real Gases, Solid State
October 24, 26	Liquids, Amorphous Solids, Colloids, Changes of State, Phase Diagrams, Thermodynamics
October 31, November 2	Solutions, Acids and Bases
November 7	Hydrogen, Oxygen and Water
November 8	Review Session for Examination II
November 14, 16	Kinetics, Equilibria
November 21	Solubility of Ionic Solids
November 28, 30	Weak Acids and Bases, Hydrolysis
December 5	Oxidation-Reduction Reactions
December 6	Review Session for Examination III
December 12, 13	Electrochemistry
December 14	Review Session for Final Examination

You will note that the order of presentation is virtually identical to that being employed during the current term. These tapes provide an extremely useful and convenient means for reviewing the material being covered in the course - USE THEM!

 

Course and Teacher Evaluation:

Student evaluation of CHEM-105 will take place on November 15 during the recitation sessions.

 

Model Kits

You will find that a molecular model kit is a very valuable accessory in CHEM-105. You will be permitted to use these model kits (excluding all associated written material) during all relevant quizzes and exams.

 

Calculator

You will find an electronic calculator to be a necessity in CHEM-105.

 

Syllabus

The syllabus, which begins on the following page, includes the following:
• Lecture dates and topics
• Reading assignments
• Examination dates and coverage periods

The weekly problem assignments for the entire term follow immediately thereafter. REMEMBER: For optimum learning progress, reading assignments should be completed prior to the lectures that pertain to them; problem assignments should be completed prior to the quizzes (and, of course, exams) that pertain to them.

Study Strategy

Chemistry is best learned, and eventually, mastered by doing, i.e., by answering questions and solving problems. To this end, your problem-solving and question-answering study strategy should proceed through the following three phases:

Phase I:

As you go through the reading assignments in Zumdahl and in the Supplementary Reading Material (REMEMBER: do this prior to the lecture that pertains to the topic being covered), do the Examples and Self-Check Exercises as they appear in the text. The solutions to the Example questions and problems are given directly in the text immediately following the Example statement. The answers to the Self-Check Exercises in Zumdahl are given in the Appendix, beginning on page A19.

Phase II:

As soon as possible after the lecture that covers the material in question, do the appropriate Problem Assignment in the list that follows these explanatory paragraphs. Work through each assigned problem and question to a final answer, to the best of your ability, before checking its correctness. If it involves an even-numbered problem in Zumdahl, first check the answer in Appendix, beginning on page A41, before looking at the worked-out solution in the Complete Solutions Guide. The worked-out answers to all of the end-of-chapter questions and problems in Zumdahl are provided in the Complete Solutions Guide. The worked-out answers to the questions and problems assigned from the Supplementary Reading Material will be handed out separately.

Phase III:

Prior to the quiz and/or examination that covers the material in question, work through the appropriate questions and problems in the CHEM-105 Examination File (Section C in the Syllabus). Worked-out answers to each question and problem are provided after each exam in the CHEM-105 Examination File. As always, do not check the answer until you have completed the question or problem to the best of your ability. Phase III is a critically important step in assessing your mastery of the material at the level expected of you in CHEM-105.

Should you desire/need additional drill and practice, the Study Guide provides yet another source of questions and problems, with answers. Answering the Cumulative Review questions on pp. 84, 156, 216, 292, 370, 479 and 548 will enable you to further measure your degree of preparedness prior to each examination.

DETERMINATION OF LEWIS STRUCTURES

1. The Octet Rule
   In forming compounds, atoms tend to achieve a rare gas configuration (complete their outer octet) by losing, gaining, or sharing the necessary number of electrons. Exception: hydrogen, whose valence is satisfied when it is associated with only two electrons (a duet).
2. In general, elements with one to three valence electrons complete their octet by losing electrons, while those with four to seven electrons complete their octet by gaining or sharing electrons.
3. Electrons are shared between atoms in pairs.
4. The octet rule does not hold for complexes of transition elements or for some (not all) compounds having a third or later period central atom, e.g., SF6, I3-, etc., where participation of vacant valence d orbitals is possible.
5. Procedure
   1. Know or, if necessary, guess the arrangement of the atoms in the compound (best guess is a symmetrical arrangement)
   2. Calculate the total number of valence electrons (group number in the periodic table x the number of atoms of each kind). If the species in question is an ion, also add the number of electrons corresponding to the charge on anions or subtract the number of electrons corresponding to the charge on cations.
   3. Indicate the electron pairs by lines or two dots placed close together; complete the octets of all atoms, sharing more than one pair of electrons between two bonded atoms when necessary; if extra electrons remain after octets are completed, assign these to the central atoms (in pairs).
   4. Write resonance structures.

RESONANCE STRUCTURES

1. Electrons are shifted in pairs.
2. No change in atomic configuration (positions of atoms) or in number of unpaired electrons is allowed.
3. Structures in which the octets are incomplete are unimportant.
4. The resonance hybrid, i.e., the actual structure of the molecule or ion, is more stable than any of the individual resonance structures. The energy of stabilization is called the resonance energy.
