Required materials:
1. Text – CHEMISTRY: The Molecular Nature of Matter and Change; 4th ed. By
Martin S. Silberberg.
2. PREPARING FOR YOUR ACS Exam in general chemistry; The Official Guide
by Eubanks and Eubanks.
3. ACHM 111 and 112 LAB MANUAL by USCA Chemistry Faculty.
4. LAB NOTEBOOK with carbonless copy.
5. Scientific calculator capable of doing logs, inverse logs, scientific notation,
Square roots, nth roots and exponents. ALWAYS BRING THIS TO CLASS.
Other Useful Materials:
Study guide, student solution manual and CD=ROM – available in the bookstore.
Pre-requisites:
Placement above, successful completion of, or concurrent registration in
AMTH 111
.
Passing grade in ACHM 111. Since most of what was learned in ACHM 111 will be needed in ACHM 112, those who earned a D or D+ in ACHM 112 are STRONGLY urged not to take ACHM 112 until they have retaken and earned a grade of C or better in ACHM 111.
Other Skills Needed:
Ability to use the Internet, access emails and do homework assigned on
Webasssign.
Course Objectives:
The goals of this course are a continuation of the introduction to foundational
chemical topics started in ACHM 111. These include transition metal chemistry,
rates of chemical reactions, chemical equilibrium involving acid/base,
precipitation, redox and complexation reactions, thermodynamics,
electrochemical cells and a brief introduction to organic and nuclear chemistry.
How to Succeed in Chemistry:
Chemistry is a difficult subject so that unless you are nobel prize winning
material, you will have to put in a lot of study time in order to succeed. The
following is a list of the things you should be prepared to do.
1. Take extensive and complete notes in class. DO NOT RELY ON YOUR
MEMORY OF LECTURE TO GET YOU THROUGH.
2. Read the book and your notes. THIS DOESN’T MEAN TO JUST READ
THE WORDS BUT RATHER TO UNDERSTAND WHAT THE CONCEPTS MEAN.
3. Do as many problems as you can from the end of the chapters in the text,
the chapters in the ACS Exam book and any study guide or student
solutions manual that you have. You have all heard this before and it is
certainly true here – PRACTICE MAKES PERFECT.
4. Do the assigned homework on Webassign.
5. Get help when needed from me (office hours) or available tutors.
Homework:
Problem solving is an integral part of learning the concepts in chemistry.
Problems will be assigned using Webassign, a we-based technology for
assigning, completing and grading homework. Each student must sigh up for
homework using Webassign. In order to sigh up, follow the procedure below.
1. On the internet explorer, type www.webaswsign.net
2. Click on sign in which is in the left margin.
3. Type in your USCA email address without the .edu in the space for user name.
4. Leave the space for institution blank.
5. In the space for password, type in the last 4 digits of yours number and click on log in.
6. On the page that comes up, click on the down arrow next to choose your
access code prefix and select the 2-digit prefix of your access code that came
with your textbook if you bought the book at the USCA bookstore. If you
bought the book elsewhere, click on PURCHASE AN ACCESS CODE
online and follow the procedure. You will have to pay using a credit card online.
7. Steps 1 – 6 registers you in the course and you now have access to all of the
assigned homework and related information.
Online homework assignments will have a starting date, usually after the lecture and a
deadline. You are responsible for knowing the deadlines for each assignment. These
assignments will provide you with practice for quizzes and exams. Since the
assignments will be based on lecture material, you should be able to work the
problems. IF YOU KEEP UP TO DATE WITH YOUR STUDIES IN THE COURSE.
Quizzes and Tests:
There will be a quiz after the completion of each chapter. There will be three hour
exams and a final exam during the semester. The final exam will be the national test
provided b y the American Chemical Society and it will cover topics from BOTH
CHEM 111 AND CHEM 112. You must take the final exam in order to pass the
course. The book “Preparing for Your ACS Examination in General Chemistry”
will be essential for your study preparation for the final examination. The final
examination is Fri., May
2 at
Laboratory:
There is no separate laboratory meeting time for ACHM 112. Rather, laboratory
is integrated into the lecture for the course. At various times during the semester,
we will move down to the lab room and carry out experiments that illustrate the
lecture material. We will them go back to the lecture room and discuss the
experiment. You will work with an assigned partner in laboratory for the whole
semester. Since efficiency in lab is essential to avoiding wasting time, you will need
to read the experiment and prepare a one page summary of the experiment before
coming to class. This one page pre-lab summary is due BEFORE CLASS STARTS.
Your summary should be done using your lab notebook so that you will have a carbon
copy to use as a reference for your review during the actual completion of the lab.
Your pre-lab write up must have each of the following:
1. Your name and your partners name.
2. The date.
3. The experiment title.
4. The lab manual page of the experiment.
5. The objective of the experiment STATED IN YOUR OWN WORDS.
6. An abbreviated procedure for the experiment STATED IN YOUR OWN WORDS.
Each pre-lab write up is work 3 points. Name, date, title and page number are worth
one point. If any of the above are missing, you will lose the whole point. The objective is worth one point and the procedure is worth one point.
The results of the experiment will be discussed in the lecture room after lab. You should write all the experimental data and calculations in your lab notebook. Your completed experimental write up is due the next lecture after doing the experiment in laboratory. Each write up should include:
1. Your name and your partners name.
2. The experiment title.
3. All data taken during the experiment.
4. All calculations done with the data and any graphs prepared from the data.
5. A one or two sentence conclusion stating your results.
Each write up is worth 7 points. One point for name and title, 2 points for data, 2 points for calculation and graphs and 2 points for the conclusion.
Honor Code:
All graded work is subject to the USCA ACADEMIC HONOR CODE. You should
read the most current USCA Student Manual to learn more about the USCA CODE
OF ACADEMIC CONDUCT which will be strictly enforced on all graded work.
Attendance Policy
Attendance will be taken every day. The Department of Chemistry has adopted the
following attendance policy for all of its 100 level courses.
1. Students are allowed a maximum of seven absences of which no more that four may be unexcused.
2. Missed assignments including tests due to excused absences may be made up at the discretion of the instructor.
3. More than four unexcused or 7 total absences will result in the loss of one letter grade from the final exam grade for the course.
Grading:
Weighting factors for graded material
Four hour exams 48 %
Final exam 12 %
Quizzes 20 %
Webassign homework 5 %
Laboratory experiments 15 %
Grading conversion = points to letter grade
85 % and up - A
75 % - 84.9 % - B
65 % - 74.9 % - C
55 % - 64.9 % - D
Below 55 % - F
To figure your % in class, simple add together your total points in each category and
then divide by the total points possible in that category. Them multiply that fraction
by the % weighting factor for that category shown above. Finally, add your %’s for
all the categories together to get your % for the course and compare it to the grade
conversion scale shown above.
Disability Statement:
If you have a physical, psychological and/or learning disability which might affect
your performance in this class, please contact the Office of Disability Services
126 A B & E, (803) 641-3609, as soon as possible. The Disability Services Office
will determine appropriate accommodations based on medical documentation.
