T EXT
Raymond Chang and Kenneth A. Goldsby: Chemistry, 11th ed. (McGrawHill, New York, 2013) is required. (The 10th edition is also acceptable; see
note below for assigned end-of-chapter problems.) The Solutions Manual is
recommended.
R EADING
You must read the assigned chapter of the text before coming to class. It is
your responsibility to acquire the factual contents of the course. The lecture
will highlight the essential information in the textbook. It will provide additional material where necessary and focus on conceptual understanding
and problem solving. Lecture notes are available for your convenience on
the class web page, http://faculty.smu.edu/whorsthe/genchem1.html,
but they are no substitute for regular class attendance.
Errors in the lecture notes, the textbook or in the ancillary material are no
excuse for mistakes on a quiz, a test, or the final.
C ALCULATOR
You need a simple “scientific” calculator for this class. Smart phones, iPods,
iPads, laptops or other portable computing devices are not permitted during exams. If the screen of your device is larger than 6 square inches or if the
device has a typewriter keyboard, the device will not be allowed. Sharing of
calculators during exams is not permitted.
ATTENDANCE
Regular class attendance is expected, and attendance will be monitored.
C ELL P HONES
Cell phones must be turned off during class.
E XAMS
There will be seven quizzes, three tests, an ACS standardized exam, and a
final.
The quizzes will be given towards the end of the class period on the following Wednesdays: Jan 28, Feb 4, Feb 11, Mar 4, Apr 1, Apr 22, Apr 29. The
1 of 9
January 2015
General Chemistry I
questions will be taken from the end-of-chapter problems assigned below,
see P ROBLEMS. The maximum number of points per quiz is 20. Only your
five best quizzes will count towards the course grade.
NO MAKE-UP QUIZZES!
There will be absolutely no make-up quizzes! Missed quizzes will be assigned a score of zero and count among the two quizzes that will be dropped.
All material in the textbook chapters listed under S YLLABUS, whether covered in class or not, may be on a test or the final.
All exams are closed book and no notes! You are allowed to use pen or pencil,
eraser, and calculator (see above), unless stated otherwise. Everything else
must be placed under the seat.
A periodic table will be provided for each exam. You are not allowed to use
any other periodic table.
No sheets may be detached from a test or the final. All loose sheets will be
immediately collected by the instructor.
Caps or sunglasses may not be worn during exams, and cell phones must be
turned off.
The instructor will return the cover sheet of a test with your numerical score.
You may examine your test or final in the instructor’s office. If you have any
questions, the instructor will discuss the test and the grading with you at that
time. Tests and the final may not be removed from the instructor’s office, and
the instructor will keep all tests and finals for six months after the end of the
term.
The tests and ACS exam will be 45 minutes long and will be on the following
dates during regular class hours:
Test 1
Wednesday, February 18
Test 2
Wednesday, March 18
Test 3
Wednesday, April 8
ACS exam Monday, May 4
You must inform the instructor during the first two weeks of classes if any of
these dates conflict with a University sponsored event.
The maximum number of points per test and the ACS exam is 100.
Tests 1–3 are free-response exams; no multiple-choice questions.
The ACS Exam is comprehensive and consists of the ACS General Chemistry Exam (40 conceptual multiple choice questions) and a short conceptmatching quiz. You need to bring a #2 pencil; calculators are not allowed.
No make-up tests.

You must take all tests, the ACS exam, and the final, unless you have a verifiable, legitimate reason for missing a test, e.g., a doctor’s note. Otherwise,
your score for the missed test, ACS exam, or final will be a zero.
If you use SMU’s Health Center, verification of medical illness and a request for an
excused absence require either of the following: (1) a hand-written note on a Health
Center prescription form or (2) a signed letter on Health Center stationery. Excused
absence medial requests must include dates and time periods. Encounter Forms
and Walk-Out Statements verify a student’s visit to the Health Center but do not
indicate an excused medical absence.
If you cannot take a test, you must contact the instructor as soon
as possible.
If you miss one test for legitimate reasons, your grade for the missed test will
be calculated by averaging your grade on the final and your grades on the
other two tests.
If you miss the ACS exam for legitimate reasons, a make-up exam will be
given during the second week of the Fall semester or at another mutually
acceptable date.
The final will be on Monday, May 11, 9 AM–9:55 AM, in FOSC 123.
Make your plans accordingly. You cannot take the final exam at any other
time! (Even if you have other finals on the same day.)
The final has the same format, and rules, as tests 1–3 and will cover material
not covered on those tests.
The final is fifty five minutes, closed book, no notes. The maximum number
of points is 100.
The final will begin at 9:00 AM sharp, and you are expected to be punctual.
It is your responsibility to know the date, time and classroom of the final.
If you miss the final for legitimate reasons, a make-up final will be given during the second week of the Fall semester or at another mutually acceptable
date.
If you cannot take the final, you must contact the instructor as
soon as possible.
D ROP
If you are unable to complete this course, it is your responsibility to formally
drop this class. The last day to drop a course is Wednesday, April 8, 2015.
Note: If a student is enrolled in both CHEM 1303 (lecture) and CHEM 1113
(lab) in the same term, a withdrawal from CHEM 1303 requires simultaneous withdrawal from CHEM 1113.
I NCOMPLETE
The SMU Undergraduate Bulletin stipulates that “A student may receive a grade of
Incomplete (I) if the majority of the course requirements have been completed with
passing grades but for some justifiable reason, acceptable to the instructor, the student is unable to complete the full requirements of the course. In accordance with
3 of 9
January 2015
General Chemistry I
University policy, at the time an Incomplete is given the instructor must stipulate in
writing to the student and to the University Registrar the requirements and completion date that are to be met and the grade that will be given if the requirements are
not met by the completion date. The maximum period of time allowed to clear the
Incomplete grade for an undergraduate course is 12 months.”
A grade of Incomplete (I) will be assigned only if (1) you have taken at least
five quizzes and two tests and the ACS exam (or three tests) resulting in an
overall grade of at least a C−, and (2) you have missed the final or the ACS
exam for legitimate reasons.
C OURSE G RADE
The course grade will be based on the numerical scores of your quizzes, the
three tests, the ACS exam, and the final:
©
max 0.165 × (quizzes + test1 + test2 + test3 + ACS exam) + 0.175 × final, 0.165
× quizzes + 0.05
ª × worst test + 0.19 × (best test + second best test + ACS exam)
+ 0.215 × final = course score
No exam score will be dropped.
No work other than your five best quizzes, the three tests, the ACS exam, and
the final can be considered for the course grade. Extra work for extra credit
cannot be accepted.
Grades will be assigned according to the break-point system: The highest
cluster will receive an A, if students in that cluster have demonstrated mastery of the key concepts (see page 7). Lower grades will be assigned to the
other clusters and will be based on the difference in score with the highest
cluster.
P OLICIES
1. Disability Accommodations: If you need academic accommodations for
a disability, you must first contact Disability Accommodations & Success
Strategies (DASS) at 214-768-1470 or http://www.smu.edu/Provost/ALEC/DASS
to verify the disability and to establish eligibility for accommodations. Then
you should schedule an appointment with the instructor as soon as possible, but no later than three days before the first exam, to make appropriate
arrangements.
T HE INSTRUCTOR CANNOT GRANT ACADEMIC ACCOMMODATIONS , SUCH AS
EXTENDED TIME ON EXAMS , UNLESS YOU HAVE PROVIDED AN ACCOMMODA TION LETTER FROM
DASS. N OTE THAT ACCOMMODATION LETTERS ARE NOT
RETROACTIVE .
2. Religious Observance: Religiously observant students wishing to be absent on holidays that require missing class should notify the instructor in
writing at the beginning of the term, and should discuss, in advance, acceptable ways of making up any work missed because of the absence.

Frequently Asked Questions
Q.: I was sick and missed a quiz. When can I take a make-up quiz?
A.: There are no make-up quizzes. A score of zero is assigned for a missed quiz, and it counts as
one of the two quizzes that will be dropped.
Q.: I was sick and missed the test. When can I take a make-up test?
A.: There are no make-up tests. However, you do need a doctor’s note to verify your illness, since
otherwise you will receive a zero on the test.
Q.: I answered a question on a test incorrectly because of an error in the book. I think I should
receive full credit for the problem.
A.: You are to demonstrate mastery of the key concepts, which implies comprehension of the
material. You should therefore be able to detect and correct errors in the book or the ancillary
material. (Bring suspected errors immediately to the attention of the instructor.)
Q.: I did not have enough time to work all the problems on the test. Can I have ten more minutes
for the test?
A.: Unless you have a letter from DASS requesting special accommodations, the test is forty five
minutes for all students. Tests are set such that if you have mastered the skills required, you
should not need more than 45 minutes.
Q.: I made a B− in this class, and in order to keep my scholarship I need at least a B. Can I do
extra work for extra credit to bring my grade up?
A.: Extra work for extra credit cannot be accepted. Seven quizzes, three tests, the ACS exam, and
the final provide ample opportunity to demonstrate adequate scholarship.
If you are concerned about your standing in this class, contact the instructor early in the term.
Do not wait till after the final.

Learning Outcomes
1. Students will be able to demonstrate basic facility with the methods and approaches of
scientific inquiry and problem solving.
2. Students will be able to explain how the concepts and findings of science or technology in
general, or of particular sciences or technologies, shape our world.
Problem Solving Strategy
(adapted from G. Polya, “How To Solve It”, 2nd ed., Princeton UP, Princeton 1973)
• Read the problem.
• Read the problem again.
• Understanding the problem
– Identify the actual problem.
– What is the area of the problem (e.g., stoichiometry)?
– What is (are) the unknown(s)? (Make a list if more than one)
– What are the data? List them.
– What are the conditions?
• Devising a plan
– Introduce suitable notation. (Draw a picture.)
– Have you seen the problem before? In a different form?
– Do you know a similar problem, a related problem having the same unknown(s)?
– Look at the unknowns and list all equations, relations, theorems, etc., that you know
and that have to do with the unknowns. (Carefully state all the limitations of the
equations, e.g., only for ideal gas.)
– Could you solve a simpler problem, a more special problem, a more general problem,
part of the problem?
– Could you restate the problem?
8 of 9
January 2015
General Chemistry I
– Could you work backwards from the unknowns to the data?
– Did you use all the data?
– Are there too many data, not enough data?
– Did you take into account all special conditions?
• Carrying out the plan
– Check each step (e.g., dimensional analysis).
– Can you see clearly that the step is correct?
• Checking the solution
– Does the result make sense (correct units, correct sign, order-of-magnitude of the
numerical value is reasonable)?
– Can you check the result, e.g., can you derive it differently?
– Can you check some (easy) special cases?
