Chemistry, 7th Edition, Stephen and Susan Zumdahl (required).  A study guide and solutions manual is also available but is not required.

 

Lab Manual:

Inquiries into Chemistry, 3rd Edition, Michael R. Abraham and Michael J. Pavelich (required).  Additional handouts will be distributed throughout the semester.

 

Equipment:

Eye protection in the form of safety goggles is required for laboratory exercises. A calculator with scientific notation, log, and natural log (ln) functions is also required. Course handouts should be purchased from the Urban Campus bookstore.

 

 

Course Description:

            This is the first semester of a one-year sequence covering general inorganic chemistry.  It is designed primarily for students entering fields such as chemistry, biology (including pre-medical and pre-dental programs), physics, pharmacy, and other majors requiring a full year of inorganic chemistry.  This course assumes a basic understanding of general chemical concepts such as those covered in a high school chemistry course or Chemistry 122 and familiarity with algebra.  CHM 122 or a full year of high school chemistry and MAT 073 (Algebra II) or two years of high school algebra are required prerequisites to this course.

            What will you learn in this course?  You will learn how to take a systematic approach to solving problems.  You will look at the structure of matter at the atomic level, and study the chemical (electrical) forces which hold matter together.  You will also be able to describe what changes occur during chemical reactions and predict the properties of elements and compounds through an understanding of the periodicity inherent in the physical and chemical properties of the elements.  Intermittently throughout our studies we will take time to focus on subject matter applicable to our daily lives, such as a study of household chemicals, energy, and environmental issues such as acid rain and depletion of the ozone layer.

 


Class Schedule:

            The class meets Monday, Wednesday, and Friday.  Laboratory experiments will generally be conducted on Fridays and Mondays. The last day to drop a class is Monday, November 5. If you decide to drop a class, you must provide written notification to the Student Records Office (any campus) of your decision. This class will not meet for the following holidays/breaks: Monday, September 3 (Labor Day) and Friday, November 23 (Thanksgiving Break).

 

Class Handouts:

            The material covered during the lecture/discussion periods drives the focus of this course.  To better facilitate learning and understanding of this material, a large number of class handouts are available to be purchased from the bookstore.

(Total = 510 pts.)

The dates of events (i.e., exams) listed above are subject to change.  The instructor will announce any changes at least one week in advance.

 


Attendance Policy:

            Attendance is required and daily active participation is expected.  Points are awarded daily for participation (approximately 1/3 point per day for a total of 15 points for the semester.)  Any absences will result in an appropriate deduction from participation points.  You are encouraged to contact me to determine what material was missed.

 

 

Pop Quizzes/Assignments:

            Pop quizzes could occur at the beginning of a class period on any given day.  These pop quizzes will focus on material that has recently been covered in class, assigned as reading from the textbook, or scheduled for laboratory activities on the day of the quiz.  To be prepared for pop-quizzes, be certain to review your notes after each class period, keep up to date on reading and practice problems, and read the introduction and procedure for all labs before coming to class.

            Throughout the semester, a few graded assignments will also be given in class.  On some occasions these assignments will need to be completed in class on the day that they are given, on other occasions they will be due during a later class period.  These assignments may pertain to either lecture or laboratory materials.

 

 

Laboratory Policy:

            There are required laboratory exercises which will be performed throughout the semester.  Due to the physical make-up of our classroom/lab, it is hazardous to keep excess lab equipment set-up.  Therefore, you are required to be present when a laboratory period is scheduled.  Students not attending lab may not turn in the lab report.  Lab reports are due one week following completion of the lab, with a 10% deduction per week for late lab reports.  If you must be absent for a lab, you will be able to make up credit for one lab report during the week of classes prior to final exams.  This is the only form of make-up credit available.  Out of the 120 lab points, 110 points are allocated to successful completion of reports and 10 points are allocated to appropriate lab etiquette – following safety guidelines, care for lab equipment, working safely, cleaning up, etc.

 

 

Quiz Policy:

            There are four scheduled quizzes, which are structured as group quizzes.  Your instructor will assign you to a group containing 2-4 members.  During a quiz, an initial period of time will be spent discussing the questions as a group.  No writing or calculating can be done during this group time, but the members should discuss together the approach which is required to answer the questions.  This will be followed by individual quiz time, when each individual will work independently to complete his/her quiz.

None of the quiz scores will be dropped.  It is expected that you will take these quizzes at the times scheduled; however, if you must miss a quiz for reasons of illness or personal emergency, you must call or e-mail the instructor before the quiz.  Under no circumstances will a makeup quiz be given simply because the student does not “feel ready.”  If you do not contact the instructor before the quiz period, a score of zero will be recorded.  Makeup quizzes must be taken within one week of the scheduled date or a score of zero will be recorded for the missed quiz. 

 

 


Exam Policy:

            You must take four unit exams and the final exam on the dates indicated.  None of these scores will be dropped.  It is expected that you will take these exams at the times scheduled; however, if you must miss an exam for reasons of illness or personal emergency, it is expected that you will call the telephone number listed above before the exam and leave a message.  Under no circumstances will a makeup exam be given simply because the student does not “feel ready.” If you do not contact the instructor before the exam period, a score of zero will be recorded.  No make-up exams will be allowed.  If you receive approval to be absent for an exam, your final exam percentage will be used to calculate a make-up score (percentage multiplied by 60 points).  You are strongly encouraged to do what is necessary to be present for all exams in order to avoid this situation. 

 

 

Bonus points:

            Quizzes: If all group members receive at least a 90% on a given quiz, the group members will be awarded 2 bonus points.  Any group member who is absent on the day of the quiz forfeits his/her right to bonus points for that quiz.

            Exams:  Each exam will contain some extra questions for which bonus points will be available.  Bonus points will be awarded for correct answers to these questions and will be added into your total exam points. 

These are the only forms of extra credit available for this course.

 

 

A note on honesty:

            Science is a field which often relies on collaboration.  During both the laboratory and lecture portion of the class, we will often share ideas and data with each other in order to help clarify what is happening and to more fully describe an idea or concept.  You are free to discuss your laboratory reports with each other, but the work that is submitted must be your own.  On exams, you must rely solely on your own knowledge.  All written work must be in your own words – do not copy from a book, another individual, or any other source.  A first offense of cheating on a laboratory report or exam will result in a score of zero recorded for the project involved (exam, lab report, etc.).  Any further incidents of cheating will result in a failing grade for the course.

 

Examples (for first offenses): 

  • If two individuals turn in lab reports with the same written response(s), both students will receive a score of zero on the report.
  • If I find a student using unauthorized aid on a quiz or exam, a score of zero will be recorded for that quiz or exam.

Study Guide

 

Reading the text

            The textbook provides a detailed description of material covered in this course.  As you daily read portions of the text, focus on the material pertinent to class discussions.  As you read, select the most important information (i.e., major concept).  After reading, summarize each major concept in your own words.

 

Pencil in hand

            Example problems are provided throughout the text as a means to test your understanding.  I suggest working these sample problems on your own as you read.  It will be crucial for you to complete the sample problems before moving forward.  Chemistry builds on itself - understanding one concept is essential to understanding the next interrelated topic.

            You may also want to note the subject matter that did not readily make sense to you.  Use the margins of the text to record your questions and bring these questions to the next class period.

 

Class time

            The direction for this course will be provided during class time.  In order for you to make best use of this time, you will need to be alert and prepared for class.  Remain involved by asking questions during discussions in order to clarify concepts in your mind.  The pace of the course will be monitored such that you will have time to record brief notes.  Record notes in your own words as best you can.  Soon after class, re-read or re-write your notes, supplementing them with pertinent information.  This is also an excellent time to check your understanding and prepare for the upcoming class period.

 

Working Problems

            Throughout the semester, you will be assigned practice problem sets and asked to work problems in class, in laboratory experiments, on quizzes, and on exams.  Generally a person’s effort working the practice problems is a strong indicator of one’s performance in the course.  When graded items are returned, use the corrections as a learning experience.
