Objectives

 

This course is a continuation of the first semester College Chemistry course, CHEM 105.  Over the semester, we will cover the remainder of the textbook that was used in CHEM 105.  Using the material and skills learned in CHEM 105, the following topics will be covered:

 

1.     The nature of solutions and the factors that affect the solubility of solutes.

2.     Chemical Kinetics or the study of the speed of chemical reactions and the factors that influence how fast a reaction can proceed.

3.     Chemical Equilibrium:  The study of chemical reactions in their equilibrium or most stable states.

4.     Chemical Thermodynamics:  The study of energy flows during chemical reactions and the criteria that are necessary for a reaction to occur.

5.     Descriptive chemistry of various parts of the periodic table.

6.     Electrochemistry:  The study of the relationship between electricity and chemical reactions.

7.     An introduction to Organic Chemistry.

8.     Nuclear Chemistry:  The study of radioactivity and nuclear reactions.

9.     Coordination Chemistry:  The study of a special type of compound that transition metals form.

 

Required Materials

 

·       Textbook:  Brown, LeMay, Bursten, and Burdge, Chemistry  (2005)  (same textbook that was used in Chem 1054 last semester)

·       Lab book:  A locally produced lab book that should be available in the bookstore.  Be sure you get the second semester lab book.  Students registered in honors lab do not need to purchase a lab book.

·       A non-programmable scientific calculator (with trigonometric functions, etc) will be required for quizzes and exams.  The calculator policy will be explained in further detail later in this syllabus.

 

Course Procedure

 

You will be expected to attend all lectures.  Lectures will be given on a TR 9:25-10:40 AM schedule.  Regular attendance is an important factor in doing well in this course.  Even missing one class may put you very far behind in the material.  It requires an awful amount of work to catch up in this course when you fall behind.

In order to keep you studying at a regular pace, online homework will be assigned using the PhGradeAssist program.  In most cases, you will be given one assignment per chapter of material.  The due date and time of the assignments will be given at the beginning of each lecture.  The problems will consist of a combination of multiple choice and numeric problems.  If you used the online homework program last semester, your login ID and password from last semester should still work on the Course Compass website.  You will need to register on the PhGradeAssist homepage for this class.  If you did not use the online homework last semester, you will need an access code to set up a login ID and password for the program.  There should have been an access code wrapped up with the textbook if you bought it at the school store last semester.  If not, an access code may be purchased online at the course compass website.  More information about this online homework program will be given out in the form of a handout during the 1st lecture and will be gone over during the 1st lecture.

CHEM 108 proceeds at a faster pace than CHEM 105.  It is also assumed that you remember the material from CHEM 105.  This course starts off at a fast pace right at the beginning of  the semester and does not stop.  You will need to start studying starting at the beginning.  If you need help, there are various sources to get help.  They include:

 

1.  Your textbook:  I generally follow the order in which the material is presented in the textbook but from a different perspective.  Reading the textbook may present you with a different way of looking at the material that may help you understand the material better.

2.  The Course Compass Website  (www.coursecompass.com) :  This site is generally used as a bridge to get to the PhGrade Assist web page.  However, the Course Compass web page also contains many features to assist you.  There is a math toolkit in the student learning resources that gives you practice with math skills including the use of logarithms, exponentials, and significant figures in calculations.  There is a section for each chapter in the book with practice problems for you to solve. 

3.  Your professor:  Dr. Arthur A. Low, Office:  Room 417, Science Building, phone:  (254)968-9144, E-mail:  low@tarleton.edu.  I will handout my schedule during the second lecture and also post it on my door.

4.  My website at Tarleton (www.tarleton.edu/~alow) At the homepage of this website are links to all the courses that I teach at Tarleton.  If you click on the link to the CHEM 108 Spring 2006 page, you will find a course description with links to the syllabus, lecture notes for each chapter, and keys to exams given last year.  There are also links to CHEM 108 classes given in previous semesters with more information that you might find useful.

5.  Supplemental Instruction:  An SI leader will be assigned to this lecture.  He or she will sit in on the class and schedule a number of help sessions per week.  Please attend these sessions regularly, not just before a test.  Usually the session just before a test is the least useful because the room is crowded with students wanting to know all the information in a very short amount of time.

6.  Tutors:  There should be lists of tutors available in the departmental office (room 117) and the Teaching and Learning Center.  Please remember that in most cases these tutors are also students with their own course work to perform.  They may not be available to you at all times that you need them.  (The same applies to the SI leader also)

 

In addition to the assigned homework, I have chosen a number of the problems from the end of the chapter that I think you should know how to solve.  The list of these problems is in the tentative schedule at the end of this syllabus.  Please try to do these problems on your own.  The answers to these problems will be linked to the course syllabus on my website.

 

Grade Evaluation

 

Your grade in this course is evaluated on the basis of your performance in lecture, lab, and the final exam.  You will be given a grade for each part.  Your course grade is a weighted average of these three grades with the lecture grade counting 50%, the lab grade counting 25%, and the final exam grade counting 25%.  An easy way to calculate the course grade is to take two times your lecture grade, add your lab grade and your final grade, then divide the sum by 4.  For example, if a student’s lecture grade was 75, the lab grade was 85 and the final exam grade was 77, then the course grade would be equal to 80.3 as shown below:

Letter grades are assigned as follows based on your course grade:  90-100:  A; 80’s B; 70’s C; 60’s D; below 60 F.  Because this is a lab science, you may not pass this course without passing both the lecture and lab portions of this course separately.   Your lab grade needs to be above a 60 and your lecture grade needs to be above a 60 in order to pass this course.  Your lecture grade may include the final exam, if necessary (if your lecture grade is below a 60, you may still pass if you pass the final exam). 

Your lecture grade is calculated based on your performance on the 3 exams given in class and your homework average.  The lecture grade is a weighted average with the average of the curved  exam grades counting two-thirds (or 67%) and your homework average counting one-third (33%).  The exam grades are curved grades on each exam based on your actual score on each exam.  The homework average is the average of your 10 highest assigned homework grades.  During the semester, I may give an attendance quiz which will give you an additional homework grade of 100 for just being in class which the quiz is given.  Attendance quizzes are given at the discretion of the professor.

There are 3 exams scheduled during the semester for:  Tuesday, Feb. 6; Thursday, March 8; and Thursday, Apr. 19.  These exams consist of 15 multiple choice questions worth a total of 40 points and 6 numerical problems wort a total of 60 points for a total of 100 points.  You will be given a raw score for each exam on the test.  Each exam is curved to a certain extent and the curve will be given to you in terms of a grade range for the scores.  For example, on a certain test a grade of 87 up to 100 is an “A”; 74 up to 86 is a “B”; 60-73 is a “C”; 46-60 is a “D”; and below 46 is an “F.”  Your curved grade will depend on where your grade lies in the range given.  For example, in the curve above, a grade of “70” on your exam would be curved to a grade of “76.”   Again, the curved grades are the grades used to calculate your lecture average.

The final exam for this course will be given during the Freshman chemistry slot on Saturday, Apr. 28 at 11:30 AM.  It consists of two parts.  The first part is a national exam written by the American Chemical Society that covers the entire year of college chemistry, both CHEM105 and CHEM108.  It consists of 50 multiple choice questions and you will have a maximum of 55 minutes to finish it.  It will be graded by scantron (green sheets).  The second part is an exam written by me that covers only CHEM108.  It will be assembled using questions given on exams given in class.  It will consist of 10 multiple choice questions and 5 problems just like a class exam.  The final exam grade will be a weighted average of your grades on the two parts with the national exam counting 40% and the second exam counting 60%

 

Makeups

 

Makeups will be given for exams only.  Makeups will be given during the week after the exam was scheduled.  The makeup exam will cover the same material but will consist of different questions.  It is up to the student to arrange a time and place to take the makeup exam.  The arrangements must be made with me in person or over the phone.

 

Calculator policy

 

It is the departmental policy that programmable and graphing calculators will not be allowed for use for quizzes and exams in all College Chemistry courses.  You will be allowed only a non-programmable scientific calculator (one with trigonometric functions, logarithms, square roots, etc.).  You can obtain a simple scientific calculator for $10.00 or less nowadays.  Violations of this rule will be treated as an act of academic dishonesty.

 

Cellphones

 

All cellphones, pagers, etc. need to set to silent vibrate in class.  The ringing of cellphones and pagers is very disruptive both to me and to the other students in the class.  If you need to be contacted by someone during lecture, please set your cellphone to silent vibrate during lecture.  If someone calls you, please leave the class, answer the phone, and then return when you are done.
