Introduction: Since prehistoric times, people have made a variety of "things" and used them for tools, weapons, shelter, transportation, food, and clothing. The "things" are derived from natural and mineral resources - the source of all chemical elements.
A modern industrial society drills and pumps, digs and mines rocks, minerals, oil, and gas from the earth; and extracts and pumps molecules and compounds from the air and water. Raw materials are refined, processed, manufactured, and synthesized into usable compounds and materials - all through the knowledge and processes of chemistry. Stop for a moment and contemplate where the nearest material that you see came from.
This is part of the Ecological Foot Print calculated in the the Topic 1. In this topic we will look at some industrial chemicals - some of which you may not use directly, but form the basis for the synthesis of many compounds and materials used in a modern society. Some questions included: What is the source of raw materials? What is the environmental impact of obtaining the raw material? How is the chemcial made from the raw materials? are there any related products? How is the product used and discarded?
General Reference Sources
Check out "Reference Sources", then "Access Science" - McGraw Hill Online Encyclopedia of Science and Technology. This is also available in the library reference section in hard copy.
Chemical Industry.Com - Gives a variety of links - may give some indications of uses of the chemical
MSDS Sheets - gives safety, hazard, and toxcity information - papers are Acrobat format

QUES. 1: Each person may choose ONE compound from those on the right column and write a brief report. This will count for the total of 6 points for the lecture on-line discussion. Please check the discussion forum so that you select a compound not already choosen.
First use the text book, then look at some of the general internet sites (sections 1-5 above). Then use various "search engines" such as Google on the internet or a Science encyclopedia to find as much as possible of the following information (hard copy or online copy - see link on right bottom to the Library.
1. Source of raw materials;
2. Synthesis reactions (words or equations);
3. Other products made with the compound or uses of the compound;
4. Environmental impacts (in making the compound or in its use and discard) or hazards;
5. Any other interesting details.
Write a short report (about 5 paragraphs) to summarize your findings. You should be able to copy from your word processor and paste into the message box of the CHM 110 Discussion Board.
Assignment: Pick ONE compound that no one else has done.
