1. Set up a research group to study the technology of coalbed methane extraction. Within this group, complete the following steps.

(a) Gather more information about the current and future status of coalbed methane production in Alberta .

(b) Summarize the environmental concerns about coalbed methane production in the U.S. state of Wyoming .

(c) State the industry's response to environmental concerns.

(d) Prepare to present your results in a format decided by your teacher and classmates.

(e) Watch for breaking news in the media and on the Internet and incorporate it into your presentation.

FAQ: Coalbed Methane

The Alberta Energy and Utilities Board (EUB) produced this information for the general public.

Farmers to Harvest Gas Profit

This article, on the Web site of University of Alberta 's Faculty of Engineering, predicts what the future of coalbed methane extraction might look like.

Coalbed Methane Extraction Threatens Wyoming's Red Desert

Grist , an on-line environmental magazine, spells out fears for the future of a wilderness area in Wyoming .

Heavy Oil Research Program Pays Big Dividends

A collaboration between the Alberta Energy Research Institute (AERI) and the Alberta Research Council (ARC) is resulting in ongoing research into the extraction of coalbed methane.

2. The operator's manuals for machines with small engines (e.g., lawn mowers, snow blowers) advise against using gasoline that has been stored since the previous season, but to use fresh gasoline instead. Alkanes are very stable compounds and unlikely to decompose, so why is this advice given?

Lawn Mower Maintenance

There is a paragraph on this page of Yardener.com about removing gasoline from the tank over winter.

Gasoline FAQs

Search this page for information on "stale" gasoline.

3. Prepare a short presentation about fused aromatic rings, such as naphthalene. Include some simple examples, their source, and their uses.

Simple Aromatic Ring

Wikipedia provides a clear description and many line-structural diagrams of fused aromatic rings. There is a link to information specifically on naphthalene.

Benzene and Other Aromatic Compounds

Scroll down through this Web site to the heading "Fused Benzene Ring Compounds."

Polycyclic Aromatic Hydrocarbons (PAHs)

CHEC's HealtheHouse describes common sources and possible health effects of PAHs as pollutants.

Use this information to answer questions 4 and 5.

Petroleum products with double and triple bonds can polymerize, and form waxy deposits and plugs in pipe systems and pipelines. One purpose of hydrotreating is to remove multiple bonds to stabilize the liquids, so that polymerization in pipes does not occur.

4. Write an equation for the addition reaction of the polymerization of ethane (ethylene) molecules, showing how two molecules can attach to each other and have a free bond at each end for further attachments.

5. Write a structure for a section of a polymer of propene (propylene) showing at least four monomer units in the section.

6. Write an experimental design to answer the question: "Are fossil fuels composed of hydrocarbon molecules?"
