Course Description
This course is a survey of the fundamental principles of chemistry. It includes the study of the
metric system, atomic theory, bonding, properties of matter, reactions, nomenclature, and
applications of chemistry to everyday life. This section also includes the study of nuclear
chemistry. It includes laboratory work. The course is for students who have not previously
completed a course in chemistry. (5 credits)
Academic Assistance
I am one of many resources available to help you succeed in this class. Here are some other
resources.
Study Groups
You should join or form a small study group for this class. The vast majority of students
find that active participation in a study group improves their performance in their classes.
Active Learning Lab
The Active Learning Lab on the first floor of the Science & Engineering Building is a great
place to study. Chemistry faculty and tutors are often available in the room, as are other
chemistry students.
Writing and Tutoring Center
Chemistry tutors are available at no additional cost in the Writing and Tutoring Center on
the second floor of Building 7. These tutors may also be available in the Active Learning
Lab. The Writing and Tutoring Center also offers one-on-one help with your writing
projects, including help organizing a paper, adding details, improving grammar, polishing
the draft, or documenting sources. Call 253.566.5184 for an appointment. For more
information see www.tacomacc.edu/wtc.
Counseling & Advising Center
The Counseling & Advising Center staff in Building 7 can help you address personal
difficulties that interfere with your studies. This includes things like test anxiety. Call
253.566.5122. For more information see www.tacomacc.edu/resourcesandservices/counseling.

Attendance
Regular attendance is necessary if you are to succeed in Chemistry 110. You should attend
every class period. If you miss a class, you are responsible for finding out what you missed
and learning the missed material before the next class session. Students who habitually miss
class are seldom successful in this course.
Attendance in lab is required and roll is taken. See the Laboratory section for the policy on
missed labs.
Instructional Methods
In this class we will use a variety of instructional methods including lectures, demonstrations,
labs, and team work. Each of these methods has its advantages and disadvantages. You are
probably more familiar, and comfortable, with some methods than with others. However, I
expect you to participate in all activities and to approach the activities in a positive,
professional manner.
Page 3 of 13
Classroom Etiquette
Students come to class to learn. It is expected that everyone will act in ways that are respectful
and that promote learning for all students and will refrain from actions that interfere with
learning. Expectations include
 Arrive on time. If you arrive late, do your best to minimize the disruption to other students.
If I will be late, I will send someone to inform you. Use the time to study.
 Stay until the end of class. If you must leave early, sit near the exit and minimize the
disruption to other students.
 Come ready to learn.
 Even quiet conversation is very disruptive during class. Except during team activities, you
should not talk to other students unless you have the floor.
 If you cannot hear what is said or see what is written, tell me immediately.
 Learn the names of the people you interact with in class and lab. Most students call me
"Mr. Hunter".
 Guests, including children, are welcome in class on an occasional basis with my prior
approval. Guests must not disrupt the class in any way. You are responsible for your
guests. Guests are not allowed in the laboratory.
 Turn off all alarms and ringers before class starts.
 Beverages are allowed in the classroom. Food should generally not be eaten in class,
except as necessary to maintain your health. Food and beverages are not permitted in the
laboratory.
 If you have the flu, stay home.
 I can usually answer a few quick questions before and after class. However, lengthy
discussions, and confidential or private discussions should take place in my office.
Laboratory
The laboratory is an integral part of Chemistry 110. It is included so you can experience
chemistry. You are expected to actively participate in all the experiments.
Before coming to the lab, study the experiment so that you are familiar with it. The assigned
experiments are listed in the calendar at the end of this document. Learn the names and
formulas of any new compounds. Prepare your lab notebook as described in the Lab Notebook
section below.
All students must follow the chemistry lab safety procedures and standard operating
procedures established by Tacoma Community College, the Science & Engineering
Department, and the instructor. Students who repeatedly or willfully violate these procedures
may face sanctions, including removal from the course, a failing grade, and referral to the
college for action under the Code of Student Rights and Responsibilities. The departmental
safety procedures for chemistry are available at
http://cms.tacomacc.edu/UserFiles/Servers/Server_6/IntranetFile/Chem.%20Lab%20Safety,%
20Procedures,%20Emergencies%20(student%20handout)ver032812.pdf.
All Chemistry 110 students must pass a Chemistry Lab Safety Quiz to remain enrolled in the
class.
Missed Labs. If you miss a lab due to illness or other event beyond your control, you are
responsible for meeting with me to arrange for a make-up assignment. If possible, contact me
before the missed lab begins. Other missed labs may not be made up.

Lab Notebook
Although there is no standard format for all science lab notebooks, there are elements that are
expected in any good laboratory notebook. These include the following.
a. The notebook must be thread-bound. Spiral, loose-leaf, perforated, and other notebooks
where pages may be easily removed or added are not acceptable.
b. Never tear pages out of your notebook or add pages to it.
c. Observations and data must be immediately recorded directly into the notebook. Do not
write them on other paper or keep values in your head. Do not delay writing them down.
Take the notebook with you if you are going to make any observations.
d. Black or blue permanent ink must be used to record all information in your notebook. Felt
tipped pens are usually a bad choice since the ink will run if water or organic solvent is
spilled on the notebook. Pencil or erasable ink should never be used.
e. If you make a mistake, cross it out with a single line. You should still be able to read the
original entry. Like this. Not like this:
. And not overwritten like this:
.
Record the correct entry nearby.
f. Measurements include units.
g. The first two or three pages should be used for a Table of Contents. This should be updated
as experiments are added to the notebook. The Table of Contents should include the
subject, page number, and date of each entry.
h. All pages should be numbered. Often you must number the pages yourself.
i. Every page in the notebook should include the date the entries were written.
j. Do not skip pages, except for the two or three pages left at the beginning for the Table of
Contents. If a page or large part of a page is left blank, cross it out with one diagonal line
and add a note like “Page Left Blank” and the date.
k. Begin each lab on a new page.
l. Many laboratory notebooks also include a Table of Abbreviations. It is not necessary to
include standard symbols or abbreviations in this table. However, if you develop your own
abbreviations or use abbreviations that are not widely known, you must have a Table of
Abbreviations. It may be immediately after the Table of Contents, or in the back of the
notebook.
You should keep complete records of your experiments in your lab notebook following the
guidelines above.
Lab Reports
Lab reports will be individual reports in which you will write responses to questions regarding
what you observed in the lab. These reports are worth 25 points each.
For each lab report, you should also do some library research on a narrow topic related to the
experiment and tell what you learned from this research. Do not simply copy sentences or
paragraphs from the web into your paper, as this is not research.
You should follow the standards of good English writing. Make frequent use of your writer’s
reference book.
Both partners must actively participate in performing every laboratory experiment.
Due dates for lab reports are given in the Calendar at the end of this document. Lab reports are
due by 8:30 am.

Graphing Guidelines
The guidelines below are adapted from the TCC Mathematics Department Student Graphing
Guidelines. You are expected to follow the graphing guidelines below on homework, lab
reports, and test questions that require an accurate graph.

Mass (g)
AXES:
 Axes and any straight lines are
drawn with a straight edge.
 The scale is clearly indicated on
each axis.
 Each axis is labeled with the
meaning and units of the axis.

or a computer is used.
Volume (ml)
 The scale is chosen so that
values between the tick marks
or grid lines can be easily interpolated.
 Scales are usually linear. Logarithmic scales may be used if appropriate. Other scales are
seldom, if ever, used. On spreadsheet programs “x-y” or “scatter” charts are usually used;
“line” charts should be avoided.
CLARITY:
 If multiple functions are graphed on a single set of axes, each is identified in a legend.
 Unrelated problems are graphed on separate axes.
 The size of the graph is helpful: it is neat, big, and dark enough to be easily read and
understood. A graph should usually occupy between a half and a whole sheet of paper.
 The scale and origin are chosen so that the data and lines use a large fraction of the graph.
SYMBOLS & ANALYSIS:
 Measured data are indicated with symbols such as circles, triangles or squares.
 The trend is shown as a line. This line usually shows the overall pattern in the data and
does not simply connect the data points with straight or curved segments.
Studying Outside of Class
Regular study is important to succeed in this class. You should plan to study at least 12 hours
each week outside of class. It is best to study every day. Use this time to review your notes,
study the text, work and rework homework problems, prepare for lab, write lab reports, and
rework quiz questions. You should begin working on an assignment as soon as it is assigned.
You should find and use the study methods that are most efficient for you.
Page 6 of 13
Homework
Homework is assigned throughout the quarter. It is essential that you do the homework. Much
of the learning occurs as you struggle with the homework. Begin working on homework
questions as soon as you receive the assignment. The order of questions on the homework is
typically the same as the order we will study the topics in class.
To become accomplished at any skill requires practice and repetition. This is true whether it is
playing a musical instrument, playing a sport, drawing, or reading. The same is true for
learning chemistry (or math or many other subjects). Solving homework problems is one way
to practice.
Solving a homework problem once is not sufficient, just as making one free throw is not
sufficient to be a good basketball player. You should frequently rework homework
problems you have answered previously, especially difficult ones. If you struggle to solve a
homework problem, then as soon as you have finished solving it, do the same problem again.
Do the problem again just before you go to sleep. Do it again the next morning. Make sure you
can do that problem under exam conditions. Keep coming back to the same problem frequently
enough that you can do it with ease under exam conditions.
Every field has material you must memorize. Most homework assignments will include some
memorization. I strongly recommend you make and use flashcards. I cut 3 × 5 cards into
quarters for this. Carry them with you and review them frequently: walking between classes,
waiting in line, eating breakfast
Submitted Work
All work must follow these guidelines.
 Use standard English. Consult your writer’s reference for details. For chemical words
and symbols, use the standards present in the course text.
 Use only black or dark blue ink, or pencil. Only ink may be used in the lab notebook.
 Use only white paper. The paper may be ruled, grid, or blank. Graphs must be on graph
paper or be computer generated. See Graphing Guidelines for more details.
 Work of more than one page must be stapled in the upper left corner. Writing that is
hidden behind a staple will not be graded.
 Do not place work in any type of binder or cover.
 Include "Chem 110 B", the assignment title, your name, and my name in the top right
corner of the first page.
All typed work should also follow these guidelines.
 Use a standard 12 point font (i.e. Arial, Garamond, Times New Roman, or Verdana)
 Double space.
 1 inch margins on all sides.
You may submit work these ways.
 Hand it to me.
 Give it to the secretary in Room 102 of the Science & Engineering Building. Make
sure my name is on the first page.
Page 7 of 13
References
You must properly reference any sources you use to complete your lab reports or homework.
References may be given using the citation-sequence system of the CSE style
(bcs.bedfordstmartins.com/resdoc5e/RES5e_ch11_s1-0003.html), or any other widely used
style. See your writer’s reference, or the Citing Sources library page on MyTCC for more
information about proper referencing.
Facts from Hill, McCreary, and Kolb or class that you use to answer homework questions do
not require a reference. Answers copied from any source and all direct quotes from any source
always require proper referencing.
Quizzes and Exams
Quiz dates are listed on the Course Calendar. The lowest two quiz scores are dropped and do
not count toward the final course grade. There are no make-up quizzes. Missed quizzes are
assigned grades of zero and are eligible to be among the two dropped quizzes. (If a quiz
receives a grade penalty due to academic dishonesty it will be included in the final course
grade. Such a quiz will not be included when determining which quiz scores are dropped.)
Quizzes may include questions about the laboratory. Quizzes may be cumulative. The scope of
each quiz will be given on the homework assignment sheet or announced in class.
A two hour final exam is given. The exam may include questions about the laboratory. The
exam is cumulative. Only exams missed due to dire emergency may be made up or taken early.
I must be notified before the missed exam if possible. Travel is not a dire emergency. Do not
schedule travel on exam dates. The exam date is listed on the Course Calendar. Make sure
your family and friends know you cannot travel on this day.
If you need to look in your text or notes to answer the homework problems you are not
prepared for the quiz or exam. When you study for a quiz, you should write one for yourself.
Then take your quiz under exam conditions – time limit, no texts or notes, etc.
The following may not be used in any way during exams and quizzes:
 Calculators with the capability of wireless communications.
 Calculators with chemistry or science memory packs.
 Dictionaries, including paper and electronic translation dictionaries.
 Cell phones, mp3 players, or any other electronic device other than a calculator.
 A calculator app.
You may not share calculators during exams or quizzes.
Calculators
A calculator is necessary for the final exam, and some homework, labs, and quizzes.
Page 8 of 13
Wireless Communication Devices
Wireless communication devices, such as cell phones, may not be used in any way during
exams and quizzes. In case of a bona fide emergency, you can be contacted through the
security office (253.566.5111).
A ringing cell phone or talking on a cell phone in class is extremely disruptive to learning and
is unacceptable. Communication devices must be silent in the classroom and labs. A ringing
cell phone or similar event during class or lab may result in a penalty for the user. A student
who talks on a cell phone in class will be asked to leave and will be referred to Student
Services for disciplinary action.
Student Suggestions and Concerns
I welcome your ideas on ways to improve learning in this class. If you have concerns about
this class, please meet with me about them in my office to discuss them. The classroom is
usually not an appropriate venue for such discussions. If we are unable to resolve your
concerns, you may wish to meet with Katie Gulliford, the Science & Engineering Department
Chair. You should see her in her office in Building 15 Room 335.
Disability Accommodations
Students are responsible for all requirements of this class, but the way they meet these
requirements may vary. If you need specific auxiliary aids or services due to a disability,
please contact the Accommodations Coordinator in the Assessment Center in Building 7
(253.566.5328). They will require you to present formal, written documentation of your
disability from an appropriate professional. When this step has been completed, arrangements
will be made for you to receive reasonable auxiliary aids or services. Access Services will
prepare a disability accommodation document. You must give me this document. Because this
is a confidential matter that requires discussion between us regarding how to provide the aids
or services, you should give me the document at a meeting in my office. This must be done
before the accommodation is needed so that appropriate arrangements can be made.
Academic Integrity
The reason to study chemistry is to learn. As stated in the TCC catalog, “Students are expected
to be honest and forthright in their academic endeavors. Cheating, plagiarism, fabrication or
other forms of academic dishonesty corrupt the learning process and threaten the educational
environment for all students.”
The following examples are written to clarify the expected standards in this class. If a standard
is unclear to you, you should ask me for clarification.
Exams and quizzes are solely your work at the time of the examination. Circumventing or
attempting to circumvent the restrictions placed on an examination is a form of cheating. The
appearance of cheating should also be avoided.
I encourage you to work together on homework, and lab reports. When you work together,
help each other understand the material. However, what you turn in must be in your own
words, the product of your own work and research, and represent your understanding of the
material. Presenting another person's words, work, data, ideas, or answers as if they were your
own is plagiarism. Even if another person gives you permission to use her work, you must give
that person proper credit. Data, words, ideas, and information taken from other sources must
be properly referenced. This includes information from the Internet. If you use another
Page 9 of 13
person's data, results, or ideas, clearly state that you have done so and give the person credit by
including a complete reference. This includes answers copied from the text. If you copy
another person's words, you must place all the text involved in quotes or indent it, and you
must give a complete reference. You must clearly show what text you have paraphrased and
give a complete reference. If you are unsure about when or how to give a complete reference,
request clarification before you submit your work. (Avoiding Plagiarism on MyTCC may
help, or simply ask your instructor.)
If you work with other students on a homework problem to such an extent that your answers
are essentially the same, state this at the end of the solution, including the names of the
students. This should occur on only the most challenging problems.
Inventing or modifying laboratory data is fabrication. If you believe your data are in error,
state why, and how you have analyzed the data. If you have not performed the experiment,
your name may not appear on the report as an author.
Coursework that receives a grade penalty due to academic dishonesty will be included in
course grading.
The consequences of academic dishonesty may range from a verbal warning to expulsion from
the College in accordance with the Code of Student Rights and Responsibilities.
Withdrawals and Incompletes
You may withdraw from the course without receiving a grade through April 10. You may
withdraw through May 22 and receive a W grade. You must withdraw through the Enrollment
Services Office in Building 7. A withdrawal after this date (WI) will be granted only in an
extreme case involving circumstances beyond your control.
If you must withdraw for medical reasons, immediately consult with the Enrollment Services
Office regarding a medical withdrawal.
If you might be activated for military service during the quarter, please meet with the
instructor to discuss your options.
An incomplete will be granted only in an extreme case involving circumstances beyond your
control. You must have completed almost all the course work. The college requires that an
Incomplete Contract be signed before you can receive an incomplete.
If you are enrolled in this class and do not officially withdraw, you will receive a grade based
on the points you earn. See the Grading section below for more details.

Grading will NOT be on a curve. You will be graded according to how well you demonstrate
Page 10 of 13
your understanding of the material taught in this course. This means that you are not
competing against each other for a few A's. Instead, you should help each other learn the
material. You are each other's best help.
The final grade will be determined as follows.
Homework: 10 @ 10 points each

Note: The number of assignments may change. This will result in a change in the total points.
The points per assignment will stay the same.
The course grade will be determined from the percentage of the possible points earned using
the table below. As described in the Quizzes and Exams section, the lowest two quiz scores are
not included in the course grading.
You may calculate your current grade at any time by calculating your percentage earned:
(total points you have earned) ∕ (total points possible so far) × 100
A 93 – 100%
A- 90 - 93%
B+ 87 - 90%
B 83 - 87%
B- 80 - 83%
C+ 77 - 80%
C 71 - 77%
C- 70 - 71%
D+ 67 - 70%

Homework Grading Scheme
Neat, orderly, complete, and correct homework will receive 10 points. Incomplete or incorrect
homework will receive points approximately proportional to the amount that is completed
correctly. Homework must follow the guidelines in the Submitted Work section above.
Homework that is difficult to grade due to disorganization or illegibility will not receive full
credit. Homework is due by 7:30 am. Because homework solutions will be provided, late
homework is not accepted if it is 25 or more hours late.
Page 11 of 13
Lab Notebook Grading Scheme
The grading scheme for the lab notebook is based on adherence to the guidelines given above
in the Lab Notebook section.
14 points for following Guidelines a – d.
2 points for following Guideline e.
3 points for following Guidelines f – h.
1 point for following Guidelines i – l.
The lab notebook is due by the beginning of the final exam.
Late Work
Homework is not accepted beyond 25 hours late since solutions will be provided at that time.
Work submitted up to 24 hours late will receive 90% credit.
Work submitted between one and five days late will receive 50% credit.
Work more than five days (120 hours) late will not be accepted.
Work will not be accepted after 3:00 pm, Tuesday, June 9.
This syllabus and calendar are subject to change. Any changes will be announced in class.
It is probably needless to recommend the subject: chemistry is
recognized as a science of such general interest, such wide
usefulness, and such universal application, that no intelligent
person can endure long to remain ignorant of its principal facts and
laws.
