The class does not use Courses.SMU (Blackboard).
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/gc1sum.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 an exam.
C ALCULATOR
You need a simple “scientific” calculator capable of doing logarithms and
exponentials for the exams. All programmable or graphing calculators,
portable computers, tablets, smart phones, or other electronic devices with
memory capability (cameras, mp3 players, watches, etc.) are not permitted at your desk during exams. Sharing of calculators during exams is not
permitted.
ATTENDANCE
Regular class attendance is expected, and attendance will be monitored.
C LASS RULES
Cell phones must be turned off during class.
No photography, audio or video recording (via smartphone, etc.) is allowed
during class.
Students may not post any material from class on the internet or personal
networking sites.

General Chemistry I
There will be five quizzes, three tests, an ACS exam, and a final.
The quizzes are ten minutes long and will be given at about 10:40, on Wednesday, June 3; Friday, June 5, Thursday, June 11; Thursday, June 18, and Thursday, June 25. The questions will be taken from the end-of-chapter problems
assigned below, see P ROBLEMS. The maximum number of points per quiz is
20.
NO MAKE-UP QUIZZES!
There will be absolutely no make-up quizzes!
You must take all quizzes, unless you have a verifiable, legitimate reason for
missing a quiz, e.g., a doctor’s note. Otherwise, your score for the missed
quiz will be a zero. If you miss one quiz for legitimate reasons, your grade for
the missed quiz will be calculated by averaging your grades on the other four
quizzes.
Any question concerning the grading of quizzes must be brought to the attention of the instructor within 24 hours after it is returned to you. Quizzes
will not be accepted for re-grading otherwise. The entire quiz may be regraded. Making alterations to your quiz is a violation of the SMU Honor Code
(see below) and will result in a score of zero.
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 (quizzes, tests, ACS exam, and the final) are closed book and no
notes! You are allowed to use pen or pencil, eraser, and calculator (see above).
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.
If you return an exam without a name, your score will zero (no make-up
exam; no extra-credit work), unless it can be established to the instructor’s
satisfaction that you actually took the exam. In that case, your score will be
the lowest score of all exams returned without a name.
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 55 minutes long and will be on the following
dates during the first period of regular class hours :
Test 1
Tuesday, June 9
Test 2
Tuesday, June 16
Test 3
Tuesday, June 23
ACS exam Monday, June 29
You are expected to be punctual, and you cannot take these exams at any
other time!
The maximum number of points per test and the ACS exam is 100.
If a test cannot be given on its scheduled day due to circumstances beyond
the instructor’s control, it will take place on the next day, Wednesday!
Tests are free-response exams; no multiple-choice questions.
The ACS Exam is comprehensive and consists of the ACS First Term General Chemistry Exam (40 multiple choice questions) and a short conceptmatching quiz. You need to bring a #2 pencil.
No make-up tests.
You must take all tests, the ACS exam, and the final, unless you have a documented, verifiable, legitimate reason for missing a test. Otherwise, your
score for the missed test, ACS exam, or final will be a zero.
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 the last day of classes, Tuesday, June 30, 10:00 AM–
10:55 AM, in FOSC 133. 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 will begin at 10:00 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 Tuesday, June 23, 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
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
three 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, 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 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.

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, unless you have
a verifiable legitimate reason.
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 fifty five
minutes for all students. Tests are set such that if you have mastered the skills required, you
should not need more than 55 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?
6 of 9

General Chemistry I
A.: Extra work for extra credit cannot be accepted. Five 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.

scientific inquiry, hypothesis development, and/or problem solving.
2. Students will be able to explain how the concepts, advancements, 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)?
8 of 9
June 2015
General Chemistry I
– 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?
– 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?
