Required Materials:
Lecture Textbook: General Chemistry, Raymond Chang, 5th Ed., McGraw Hill, Boston,
2008, Text ISBN 978-0-07-304851-2
Lab Textbook: Laboratory Experiments In General Chemistry: CHEM110 and CHEM111,
Version 8.0, 2005, Towson University. This is an “in-house” manual. Make sure you get the
correct version!
Laboratory Goggles: Must be ANSI approved and cover the eyes completely. The
chemistry club sells two varieties ($10.00). They are cheaper and more comfortable than the
goggles sold at the university bookstore. Additionally, there are a limited number of used
pairs for $5.00, but they sell out quickly. The used pairs have been sanitized.
Laboratory Notebook: Must have carbon copy pages that can be turned in as a duplicate of
what has been recorded in the notebook. These are also sold by the chemistry club ($11.00),
and at a price that is cheaper than the bookstore.
Calculator: A scientific calculator is recommended for the course. The calculator should be
able to display scientific notation, be able to take roots of numbers, raise numbers to any power,
take logarithms and antilogarithms in base 10 and base e. I will not allow programmable
calculators for this course due to increasing incidence of students storing illegal information in
the memory of this variety of calculators. I suggest a calculator, such as the TI36X, which is
solar (no batteries needed) and simpler to operate. Note: Palm pilots and cell phones may not
be used for exams!
Attendance:
Prompt attendance is strongly recommended. If you are late or miss a lecture, it is your
responsibility to acquire information given out during lecture. Make-up exams will not be given.
In the event an exam is missed, the final exam will be weighted an additional 7.5 % to cover points
missed. If you are more than 20 minutes late for a lab lecture, you will not be able to perform the
experiment and will receive a grade of 0 for that lab. If you miss any lab session, you may make up
the lab only if you have a verifiable excuse for your absence. Please take into consideration that it
takes the same amount of time for the lab manager to prepare a lab for one person as it does for an
entire section.
Please turn off cell phones, beepers and MP3 players while in class out of consideration for your
classmates. It can be very distracting – especially during an exam! In addition, class time is not a
social hour. Please refrain from casual conversation during class time. You will be asked to leave
the classroom if you disrupt the class.
Blackboard website:
I will be using Blackboard, an online information hub for coursework. I hope to post useful
information, the challenge problems and have a chance for you use the discussion board for help
from your classmates and me on course material. Any suggestions from those of you who have used
Blackboard in the past are welcome! To access Blackboard, you need to create an account for this
course. To do so, launch your browser and open http://learnonline.towson.edu. Click Create
Account, follow the instructions on the screen and fill in the form accordingly. The username must
be lower case. If you have trouble, please see me and I’ll see what I can do to help you. Once you
have logged into the LearnOnline, click the Courses tab and locate this course using either the
course ID or my name. Next, click Enroll and then Submit.
ARIS website:
The textbook has a useful website: http://www.aris.mhhe.com which is a great resource of
supplemental material. You do not need to sign in or register for the site and it is free of charge. In
particular are many animations (for you “visual learners”) and self-assessment quizzes. Chose
“chemistry” as the subject, Chang, 5th ed. as the textbook. When the textbook section appears,
choose the self-study tab at the upper left corner of the tool bar and go nuts! Pick a chapter and see
what you find!
Lab Reports:
Lab reports and prelab assignments will be due at the beginning of lab lecture. Since the answer to
many of the prelab questions are given during lab lecture, late prelabs will not be accepted. Any lab
report handed in after lab lecture will be considered late, and a grade penalty will be assessed. The
grade penalty is a reduction of one letter grade for each day the report is late. Once the graded lab
report is returned to the class, you may not submit a late report. Lab reports will be graded based on
completeness (all parts of the report are included), accuracy of the calculations (where appropriate),
accuracy of answers to prelab and post lab questions, and accuracy of results (where appropriate. If
the report is incomplete or has calculation errors, points will be deducted accordingly, so it is to your
benefit to check your report carefully for completeness and check your calculations for accuracy
before submitting the report. If you do not attend lab and do not turn in a report, a grade of 0% is
given. If you attend a lab, but do not turn in a report, a grade of 50% is given. A complete report
that is turned in will receive a minimum grade of 70%. Please feel free to seek help in the tutoring
center, should you need help with your reports. Reports should be prepared using a word processor
using single spacing. Graphs should be prepared using Excel. Other graphing programs may be
used, but please show a sample graph to your lab instructor for his/her approval. CurveExpert is a
easy to use scientific graphing program that is used. If you want a copy of CurveExpert, see me and I
will tell you how to either download the program or provide you with a copy. All graphs and tables
should be properly formatted to include labels and units. I will accept reports via e-mail but only to
prove that you have completed the report. You must bring me a hard copy identical to the e-mailed
report by noon of the next day. You will be working with a lab partner. Please make sure that your
lab report is not identical to your partner’s. This carries the penalty of plagiarism. The lab schedule
is at the end of the syllabus.
Grading:
4 lecture exams
10 – 13 quizzes (drop 3 lowest)
15 laboratory experiments
1 – 3 challenge problems
1 final exam (cumulative)
30 %
10 %
25 %
5%
30 %
Your course grade will be based on the percentage of points earned. As you can see, a good course
grade is achieved by performance in all aspects of the course. Don’t count on any one section of the
course to either pass or fail you. The final exam is cumulative for good reason. The material you
will have learned in Chem110 is essential background material for Chem111 and beyond. Course
grades will be assigned as follows:
93 –100
90 – 92.9...
87 – 89.9…
83 – 86.9…
80 – 82.9…
A
AB+

70 – 72.9…
67 – 69.9…
60 – 66.9…
C+

Your course grade is calculated as a weighted average:
Final course grade = 0.3(lecture exam average) + 0.1(quiz average) + 0.25(lab average) +
0.05(challenge problem average) + 0.3(final exam grade)
Also, you must pass both lab and lecture in order to pass the course. In over 20 years of teaching,
I have never had to curve grades. 
Cheating
I “take no prisoners” when it comes to people cheating on exams. If you want to guarantee yourself
an F in the course, then cheat on the exam. All incidences of cheating will be reported to the
University Academic Standards Committee, and you will risk dismissal from the university and have
a notation of academic dishonesty placed on you permanent school record. It would thus seem that
flunking an exam, if unprepared, would be preferable. Additionally, a lab report must not be
identical to that of another classmate.
Tutoring
Since I am in charge of the tutoring for the sciences—please feel free to seek me out in the tutoring
center. Tutoring is available, free of charge at the Chemistry Tutoring Center located in SM538. No
appointment is needed to access the service. The general hours of operation will be: Monday thru
Thursday from 8:00am - 6:00pm. Check the schedule located on the door for specific times—there
may be a few “gaps” in the times specified above. I may have other duties to attend to at times, such
as meetings, so I may not always be there when scheduled. When this happens, I will try to post a
sign in advance, and/or let you know during lecture. I encourage you to avail yourselves to this
service—many students do well in chemistry courses with help from the tutoring center. Also
available as a resource is the tutoring center’s home page: http://pages.towson.edu/ladon. There are
well over 150 pages of study aids there for your use. The Academic Achievement Center, CK505,
offers numerous workshops throughout the semester to build your study skills. I urge you to take
advantage of these free workshops to improve your study skills and thus success in your coursework.
General Advice
1)
Don’t procrastinate—a lab report isn’t going to magically appear on your monitor in the 45
minutes before it is due, nor is 3 weeks worth of lecture material going to download into your
brain in 3 hours before the exam.
2)
Work as many problems from the textbook as you can. If you can only correctly answer 50%
of the problems, then you have a good idea of your potential test score—GET HELP!
3)
Let the information build—the subject gets easier, not harder, if you do this. There are only
24 hours to a day. If you have to relearn what you forget, at some point there won’t be enough
time to do all the work needed to review the old material and learn the new material. Do
whatever it takes you to put information into long-term memory. (Association, repetition,
reinforcement—using flashcards you can make, working problems, thinking about the concept,
talking or explaining the concept to someone else, rewriting notes, mnemonic devices.) Look
over your class notes from day one to the current day at least once a week to refresh your
knowledge. This will make studying for a cumulative final exam easy!
4)
When taking an exam, all you can ask of yourself is the best you can do—so don’t stress.
