PART III TOXIC ORGANIC CHEMICALS
PART IV WATER CHEMISTRY AND WATER POLLUTION
PART V METALS, SOILS, AND WASTE DISPOSAL
Welcome to the home page of the course Environmental Chemistry. This page contains information about this web course, as well as links to the course itself.
This course is a supplemental guide to the Baird and Cann textbook which is very good. The textbook covers the basic chemistry behind environmental problems dealing with air, energy, toxic organic chemicals, water, and other issues.
One year of college chemistry is required. One term of organic chemistry is required.
Anybody in the world who is able to participate is welcome to do so. Also, to properly participate, you should have access to the various required materials listed in the next section.
The textbooks used in this course are:
The Baird and Cann textbook comes with a number of homework problems.
The following problems should be attempted BEFORE beginning the course tests.
1-1,3-1,3-10,AP 3-2,AP 4-2,,AP4-7, 5-6,5-7, 5-10,AP 5-3, AP 5-8, 6-1,AP 6-2,7-8,8-1,8-3,AP 8-1,9-2, 10-11,10-13, 11-5,,11-11,AP11-7,12-6,12-8, 13-6,AP13-1,14-11,14-12,15-7,16-1,16-4,AP 16-1, AP 16-3,
To see if your solutions are correct refer to the Solutiuons Manual. If you have questions about this homework and the problem solutions, contact your instructor BEFORE beginning the tests.
There will be three tests. The first one will be due 20 APRIL, the second one will be due on 10 MAY and the third one will be due on 7 JUNE. All tests are due at 1700 on the due date. The total number of questions on all the tests combined will be 50. The 50 questions will be keyed to the course learning objectives. 35 of the 50 questions are taken directly from the textbook. These questions are marked with a *. All you have to do is to look up the questions in the textbook, read the solutions in the solutions manual, adjust the solution to the new data in the problems and copy the answers into the tests. This will get you a C grade or an S grade if you are taking the course S/U. The remaining 15 questions are more advanced and depend on you being able to use the material in the chapters to solve new problems.
All constants, equilibrium and otherwise, used in the test are taken from the values given in the Baird and Cann textbook.
Grading criteria: 45 correct questions =A, 40=B, 35=C, 30=D, < 30=F. We don't give + or - grades or I grades
These tests are just like in-class tests. You are not to collaborate with others in answering the questions. We cannot offer hints on how to work the problems. In an in-class test. would you ask a proctor about how to solve a problem? Like all proctors, we can clarify what is being asked in a question, but not how to answer it..
Warning: Because of the large number of students enrolled in the Chemistry web courses, it is very difficult to answer student inquiries concerning content, etc during the last two-three weeks of the term. We will try our best to answer all content inquiries within 7 business days, but it may not be possible during the last two-three weeks of the term. We CANNOT answer inquiries during the last week of classes. Please plan on doing your work as soon as possible.
A note about procrastination. Procrastination can be a big problem in this course. We are asked to do the tests in Blackboard 9.1. Blackboard 9.1 has known problems. It will occasionally lock up and the only practical way to cure the problem is to log out and log in some time later. Normally that is not a problem, EXCEPT if you are trying to do the tests on the last day. THEN YOU ARE SCREWED! ! Similar comments apply about computer problems on your end, illness, etc. BE SMART. Do the tests a week before they are due. DO NOT OPEN MULTIPLE COPIES OF A TEST AT ONCE. Blackboard may lock up and charge you with a try even though you have not submitted the test. DO NOT GIVE UNITS FOR ANY ANSWER. ALL ANSWERS ARE NUMBERS WITH NO UNITS. IF YOU USE UNITS BLACKBOA D WILL JUST SAY YOUR ANSWER IS WRONG. ENTER ANSWERS IN THE FORMAT 3.64e-05, or 0.0000364 DO NOT USE ANY OTHER FORMAT FOR THE ANSWERS.DO NOT WORRY ABOUT SIGNIFICANT FIGURES. Blackboard has tolerances built into the test protocol which will cover this.
NOTE THAT IF YOU COMPLETE A TRY AT THE TEST AND START A NEW TEST, THAT WIPES OUT YOUR OLD SCORE !! ANY UNFINISHED TEST GETS A SCORE OF ZERO AND COUNTS!!
Here is the tentative list of topics to be discussed, in approximate order of introduction:
Currently the primary way with which you will be given assignments and material will be having it posted on this webpage. The current way for you to communicate with your instructor is by email. Remember the tests are just that, tests. We are happy to answer general questions about the subject material and the learning objectives, or the kind of clarification questions that you would ask a proctor during an exam. We will not answer questions on how to work a specific exam problem. Please be sure that all course inquiries come from valid onid email addresses. We cannot answer questions from non-onid addresses.
. THE FIRST TEST IS DUE 20 APRIL, THE 2ND TEST IS DUE 10 MAY AND THE THIRD TEST IS DUE 7 JUNE.
ALL TESTS ARE DUE AT 1700 ON THE DUE DATE.
