Incomplete Grade
To get an incomplete (I) grade, you must have a passing grade for the work already done. An
incomplete will not be given for work missed because of unexcused absences. To have an excused
absence, you must have a medical reason documented by a physician, or you must present an
acceptable reason in writing to your lecturer. Unless you choose to remove the incomplete by
repeating—and paying a second time for—the entire course, only the missing exam, etc, may be
made up. Grades of I must be converted to passing letter grades before you may enroll in
Chemical Principles II.
Course Policies
Attendance
As adult students, you are responsible for managing your own learning habits in this
course. This includes complying with announcements, deadlines, and any scheduled events
communicated either verbally or via Blackboard by your instructor. Regular attendance to
lecture is required. If, for some reason, a student should miss a class, s/he must contact a
classmate to review missed content.
•Scheduling a Make-Up in the Event of a Known Scheduling Conflict: If a student knows in
advance that s/he will miss a scheduled lab, s/he is required to contact the instructor at
least 48 hours in advance to make alternative arrangements.
•Scheduling a Make-Up in the Event of an Emergency: In the event of an unforeseen
emergency or event which prevents the student from attending a scheduled lab, s/he is
required to contact the instructor no later than 24 hours after the scheduled time of the
3
lab. Failure to attend a lab and to comply with this policy will result in an irreconcilable grade
of 0 for that experiment. Proper documentation to justify absence (i.e. physician’s note on
letterhead stationary) must be presented to your instructor.
Lab Cancellation Policy: In the event your lab section is canceled due to
weather conditions,
you will perform the missed experiment the following class period, and will continue with the
schedule in order as listed on the last page of
this handout.
Lab Make-Up Contact: Students missing a lab must contact Dr. Edward Witten, the Laboratory
Coordinator in the Department of Chemistry and Chemical Biology at e.witten@neu.edu or (617)
373-4508, in advance, to schedule a mutually convenient make-up time within three days of the
missed assessment. Students failing to appear for lab without prior arrangements for a make-up will
be assigned an irreconcilable grade of 0%.
Chemical Safety
CHEMICAL RESPONSIBILITY
It is important for every student to have a basic understanding of the dangers and hazards associated
with thoughtless disposal of chemicals. We no longer live in an age of a "throw away society". It is
our duty to protect the environment by disposing of toxic and hazardous chemicals properly. You
will be clearly advised in each experiment, by way of a handout sheet, the dangers of each chemical
to be used during that day's experiment and the proper method for disposal.
Handling of Chemicals
Some chemicals may be perfectly safe to dispose of down
the drain, while others will be placed
in waste disposal bottle. Make sure you follow these instructions. If you are not sure of what to do
with your waste chemicals, check with your lab instructor and be sure they go into the proper
bottle, appropriately labeled. The hoods will often contain bottles for several experiments. It is
also possible, that your experiment may require more than one waste bottle. Again, read the label
and dispose of your chemical waste into the proper bottle. Post-lab questions are likely to ask about
chemical responsibility.
Two chemicals that need specific mention are mercury and acetone. The
general chemistry
labs should have no mercury present. If you happen to have
a mercury thermometer, bring it to
the stockroom to be replaced by an alcohol filed thermometer. A mercury thermometer has a
silver liquid in the bulb, an
alcohol thermometer is filled with a red colored liquid. No
acetone or mercury
should be poured into the drains in this building. The small amount of
acetone
to be used in this course should be placed in its appropriate waste container.
The
state of Massachusetts monitors the level of these chemicals leaving the
building and can
determine if students are not complying with proper waste
procedures. If you are going to be
taking organic chemistry in the future this warning will be even more important in these courses.
All chemicals should be handled with caution. If you get any chemical on yourself, wash the
affected area with plenty of soap and water. Disposable gloves are available from the stockroom.
Report all chemical spills to your lab instructor and the personnel in the stockroom. Chemicals
should be kept where they are found. You should take only what you need and close and tightly cap
4
the container. Clean-up any material spilled at once (check with your instructor for proper clean-up
instructions). Do not remove any chemicals from the laboratory.
Clean up: You are responsible for cleaning up your work area after each lab.
You should
wash your hands with soap and water after finishing your
experiment each week. Hand soap is
available in the lab.
Clothing: You should wear clothes that cover the maximum amount of the body. Shorts and
sandals are not recommended for lab.
Glassware: Clean all glassware before leaving the lab for the day.
Disposal: Dispose of all chemicals as outlined on the chemical responsibility sheet
Accidents: Report any accident to your lab instructor and to the stockroom immediately.

Academic Honesty and Integrity Statement
The University views academic dishonesty as one of the most serious offenses that a student can commit
while in college and imposes appropriate punitive sanctions on violators. Here are some examples of
academic dishonesty. While this is not an all-inclusive list, we hope this will help you to understand some
of the things instructors look for. The following is excerpted from the University’s policy on academic
honesty and integrity; the complete policy is available at
http://www.cps.neu.edu/about-cps/policies-and-procedures.
Cheating – intentionally using or attempting to use unauthorized materials, information or study aids in an
academic exercise. This may include use of unauthorized aids (notes, texts) or copying from another
student’s exam, paper, computer disk, etc.
• Fabrication – intentional and unauthorized falsification, misrepresentation, or invention of any data, or
citation in an academic exercise. Examples may include making up data for a research paper, altering
the results of a lab experiment or survey, listing a citation for a source not used, or stating an opinion
as a scientifically proven fact.
• Plagiarism – intentionally representing the words or ideas of another as one’s own in any academic
exercise without providing proper documentation by source by way of a footnote, endnote or
intertextual note.
• Unauthorized collaboration – Students, each claiming sole authorship, submit separate reports, which
are substantially similar to one another. While several students may have the same source material,
the analysis, interpretation and reporting of the data must be each individual’s.
• Participation in academically dishonest activities– Examples include stealing an exam, using a prewritten paper through mail order or other services, selling, loaning or otherwise distributing materials
for the purpose of cheating, plagiarism, or other academically dishonest acts; alternation, theft,
forgery, or destruction of the academic work of others.
• Facilitating academic dishonesty – Examples may include inaccurately listing someone as co-author of
paper who did not contribute, sharing a take home exam, taking an exam or writing a paper for
another student.
