Introduction
The purpose of this course is to provide you with an introduction to
atomic and molecular structure, as well as molecular properties. We will
also discuss general principles of reactions including stoichiometry,
equilibrium and some thermodynamics. The overall goal of this course is to
adequately prepare you for CHEM 231 (Organic Chemistry I), which will
cover introductory organic chemistry, including organic structure, organic
reactions and organic reaction mechanisms.
Text and Other Materials
The text we will use for this course is:
Tro, N.J. Chemistry – A Molecular Approach – Second Custom Edition for
University of Maryland – CHEM 131; Pearson, 2011, ISBN 1-256-10448-5
(Note – the older “blue cover” is also acceptable – it is missing the chapter
11 problems, but those are online in the “Course Documents” folder on the
elms page.)
The text should also come with a Mastering Chemistry (online web-based
learning) access key for online homework at
http://masteringchemistry.com/. See the document entitled
“MasteringChemistryRegistration.pdf” under “Technology Documents” on the
Blackboard page for information on how to sign up for and log into Mastering
Chemistry. If the card is not bundled with the textbook, you can purchase it
separately or but an access key online.
You will need a “Response Card RF” or “Response Card XR” or “Response
Card RF-LCD” (a “clicker”) by Responsive Innovations. Alternatively, you
may use your iPhone or iPod or Blackberry or laptop computer as a clicker.
This must be registered online at http://webreg.turningtechnologies.com.
For the User ID line, enter your nine digit student ID from your university ID
card. A document referring to the use of iPods or computers as clickers is in
the “Technology Documents” folder, entitled
“RWWParticipantQuickguide.pdf”. To use your
iPod/iPhone/Blackberry/laptop as a clicker, you need to purchase a clicker
code – click the “Student” tab at http://clickers.umd.edu for information on
how to do this. More information about clickers can be found at
http://clickers.umd.edu.
Even if you use a web-enabled device, you MUST register your clicker ID at
http://webreg.turningtechnologies.com.
I will use ELMS for entering grades, e-mailing the class, posting exams (the
ones given this semester as well as old exams for practice), answer keys,
recommended problems, and other course documents. You can log on to
the course ELMS page by going to http://elms.umd.edu. The login and
password are the same ones you use for your university e-mail.

Clickers: We will be using a personal response system (“clickers”) in class
this semester. Clickers can be purchased at the bookstore by asking at the
counter on the lower level. You can use an “RF” or “RF-LCD” or “XR” clicker
(the old gray clickers or the newer blue and white clickers, respectively) or a
web enabled portable device (an iPod touch, iPhone, laptop or Blackberry).
Once you purchase your clicker, you must register your clicker with the
university as described above, even if you use a web-enabled device.
Additional information regarding clickers can be found by clicking the
“Student” tab at http://clickers.umd.edu. This website will give you
information on purchasing your clicker, registering your clicker, using your
clicker, and what to do if your clicker is lost or stolen. It also includes
information on purchasing a license code for a web enabled portable device.
For instructions on how to use your clicker, consult the appropriate
documents in the “Technology Documents” folder on Canvas.
There will be ~20-30 in-class clicker questions over the course of the
semester that you will be required to answer. These questions will be on
material previously covered in the course (usually in the previous lecture or
two), and they will be a way to make sure you are keeping up with the
material. The first couple of minutes of every class will be devoted to
administrative announcements and one or two clicker questions. It is most
helpful that you answer the question on your own without asking your
friend(s) or looking back in your notes. I will ask that the class remain silent
during this question.
Each clicker question is worth 1 point toward your final grade: ½ point for
participation and ½ point if you answer the question correctly. Occasionally,
some questions may be worth 2 points – 1 point for participating and 1 point
for getting the answer correct. You will be able to keep track of your clicker
points on Blackboard.
After the last day for schedule adjustment, any problems with your clicker
(such as a new clicker ID to replace a lost clicker or any technical issues)
need to be directed to me.
Clicker points will be uploaded at the latest by the day following the in-class
clicker question(s). You should check your points on a regular basis to make
sure your answers are being recorded and that your points show up correctly
– there are always technical issues regarding some clickers and the sooner
that you and I resolve these issues, the better for the both of us. I will not
address any clicker issues after the final exam is given.
Homework: This semester, we will use the MasteringChemistry system for
homework. You need a MasteringChemistry access code to gain access to
the website and complete assignments this semester. If you purchased your
text in the bookstore, the MasteringChemistry access code should have been
packaged with your text. If you purchased your text elsewhere, you will
need to purchase a MasteringChemistry access code. The campus bookstore
should have stand-alone codes available. You can also purchase a code
online. See the “MasteringChemistryRegistration.pdf” document in “Files”
then in “Course Documents” on the Canvas page for more information on
purchasing a code online.
To register for the course, follow the directions on the
“MasteringChemistryRegistration.pdf” document on the Canvas page under
“Course Documents.” You will need the course code, which is also on the
document on Canvas: FRIEDMANCHEM131SPRING2013
NOTE: If the registration process prompts you to sign up for a specific
textbook and edition, use “Tro, Chemistry: A Molecular Approach, 2e.” This
means the second edition.
There will be 10 homework assignments during the semester, each with 10
questions worth 1 point each. You will be given one week to complete the
assignments. You will have three attempts for each question. The
assignments entitled “Introduction to Mastering Chemistry” and “Math
Review” will be available for the entire semester, and will NOT count towards
your final grade. They are there simply so you can familiarize yourself with
how to input answers and learn how to use the interface, and to review basic
algebraic manipulations. The Mastering Chemistry system maintains grades
for all assignments, and may include this score too in the gradebook – that
said, at the end of the semester, scores on these assignments will be
discarded.
Assignment due dates are listed on the syllabus as well as on the Mastering
Chemistry page itself. Typically, assignments will be available on Monday
mornings by 10 a.m. and due by Tuesday of the following week at 11:59
p.m., with some exceptions based on the locations of exams and holidays.
Exams: The in-class exams will be on February 26th, April 9th and May 7th.
The final exam is on May 13th from 10:30 a.m. -12:30 p.m. Please note that
on the Testudo final exams page, our final exam is listed under Common
Final Exams (Item #4) and thus we will not fall under Standard Final Exams
(Item #1). The location of the final exam has not been determined yet.
When I found out the location, I will make multiple announcements in class
and put an announcement on the Canvas page.
Only non-programmable calculators will be allowed during the exams. A
scientific calculator is strongly recommended. No electronic devices (other
than your calculator) will be permitted during an exam. Each student is
required to keep his/her University of Maryland photo ID on the desk during
the exam. If you know you will have a conflict with the date of an exam,
such as a religious observance, you must be in touch with me by the end of
schedule adjustment (February 5th). If you are ill on the day of the exam,
you must contact me before the exam to make alternative arrangements.
An e-mail or voice mail message PRIOR to the exam time will suffice. Make
up exams will be given only with a valid documented University excuse.

Note: Chapter 1 contains a series of important topics such as states of
matter, significant figures, precision and accuracy. I will not cover these
topics in class, but I have prepared a document on the Blackboard page
under the “Important Material from Chapter 1” listing that summarizes the
most important subjects in Chapter 1. I have also put suggested problems
from chapter 1 in the “Recommended Problems from the Text” document in
“Files” then in “Course Documents” on Canvas.
Policies:
Academic Integrity: The University of Maryland has a nationally recognized
Code of Academic Integrity, administered by the Student Honor Council. This
Code sets standards for academic integrity at Maryland for all undergraduate
and graduate students. As a student, you are responsible for upholding
these standards for this course. You should be aware of the consequences of
cheating, fabrication, facilitation, and plagiarism. For more information on
the Code of Academic Integrity, please visit the
http://osc.umd.edu/OSC/AcademicDishonesty.aspx.
You are responsible for understanding the content of the Code and behaving
in a manner consistent with the Code. There will be zero tolerance for any
violations.
Make-Up Exams: Only university-excused absences will be accepted for
missed exams. Proper documentation is expected. You must contact me
within 24 hours of the missed exam. Failure to meet these three
requirements results in a ZERO for the missed exam.
Learning or Other Disability: If you have a disability or other documentation
from Disability Support Services, please make an appointment to discuss
available accommodations to maximize your experience in this course.
Learning disabilities must be documented by DSS prior to receiving
accommodations.
Withdraw: The last day for schedule adjustments is February 5th. The last
day to withdraw is April 10th.
Re-Grades: In the event that you feel that points were unfairly deducted
from your exam, regrades are permissible for up to one week from the date
the exam is handed back, or the date the answer key is available, whichever
is later. On a separate sheet of paper, write an explanation of where and
why you feel that you deserve more points than you were given credit for.
Regrades are to be submitted directly to me. Regrades in which the
explanation is written directly on an exam will not be accepted.
At my discretion, I may decide to regrade your any part of or all of your
exam.
Neither your TA nor I will discuss with you whether or not you should submit
a regrade.
Addition errors that unfairly subtracted points from your exam score will be
corrected, but not regraded.
Grades in General: Ultimately, it is your responsibility to make sure that
your grades are recorded correctly in the gradebook on Canvas, and that
they remain in order throughout the semester. Due to the sheer volume of
graded material throughout the semester (clicker points,
MasteringChemistry grades and exams), there will inevitably be a small
number of technical or mathematical glitches regarding grades. I will try to
minimize how often these events occur. Errors in grades (either regrades or
a mis-entered grade on Canvas or Mastering Chemistry marking a correct
answer wrong) should be brought to my attention as soon as possible –
please note that there is a statute of limitations on regrades as described
above. You should check Canvas often to make sure your scores appear as
they should. After the date of the final exam, I will not entertain exam
regrades (as per the section above), nor will I entertain grading issues
regarding the online homework or clickers.
Assistance:
“There is no shame in not knowing – only shame in not asking.”
- Harris J. Silverstone III
I am available for help with and or discussion about any aspect of this
course, and I will have office hours on Monday and Tuesday from 9:00 a.m.
to 11:00 a.m. in my office (Chemistry 1130B). Office hours are times that I
am guaranteed to be in my office. Please realize that occasionally someone
will schedule a meeting that I am required to be at that conflicts with my
office hours.
You are free to e-mail me a question, call me, or make an appointment
to meet with me outside of designated office hours if you cannot make my
regular office hours or if you choose to do so. You are also welcome to stop
by for help when you are nearby, although my availability is not guaranteed
should you choose this option – that said, I am in more often than I am out.
At any rate, finding me for help during the semester should not be a
problem.
Staying on top of the material is an important duty that you must do
in order to do well in this course. Once you feel you are beginning to lag
behind or get lost, I would encourage you to meet with me as soon as
possible so we can get you back up to speed. Not doing so may affect your
grade in an undesired manner, as well as your performance in CHEM231.
Other Suggestions:
•
•
•
Add my e-mail address (on the top of the first page of this syllabus) to
your whitelist/list of preferred senders. U.Md. addresses have been
used to spam some hotmail and Gmail accounts recently, so some
valid messages from the umd domain may be blocked. If I am on
your whitelist, messages from me will not be blocked. This is
particularly important if your umd address automatically forwards to a
Gmail or hotmail account.
Attend all lectures – If you choose not to do so, you will lose clicker
points, and you will not hear my lectures. I may explain things in the
textbook in a different way or provide alternative methods for working
problems or understanding a concept. Occasionally, I will teach
something that is not in the book. If it is covered in class, it is fair
game for an exam. It is in your best interest not to miss lectures.
Go to your discussion sections – Your discussion sections will be
smaller than the lectures and are places where you can get your
questions addressed in a more personal manner (although I will
answer questions during lecture). The point of the discussion section
is to fill in the gaps in the material that the lectures leave, to help you
better understand the material from lecture, and to practice problems
related to the lecture material.
•
•
Work the end of chapter problems – On the Blackboard site for the
course is a document entitled “Recommended Problems from the Text”
in the “Course Documents” folder. These are problems that I feel are
a good way to verify your understanding of lecture and textbook
material. There are far too many to do considering your other classes
and assignments, but nonetheless, working on a healthy number of
these per chapter will reinforce your understanding of the material.
Get help the minute you begin to have trouble with the material. This
course is not only a course in and of itself, but it is also preparation for
CHEM231, Organic Chemistry I. Any difficulties you have with the
material in this course may lead to disastrous consequences in
CHEM231. Your TA and I are here to help you learn and to prepare
you for your future chemistry courses, so take advantage of us!!!
