Chem week 5

And choose one:

1.  Consider This 6.23 (page 269) – Reexamine Figure 6.22.  Although it may be tempting to blame acid rain for the damage, other agents may be at work.  View possible other culprits for yourself by taking a photo tour of our nation’s capitol, courtesy of a website on acid rain provided by the United States Geological Survey.  A link is provided at the textbook’s website.  What kinds of damage do the photos show?  What promotes damage by acid rain?  What else has caused the deterioration?

2.  Consider This 6.24 (page 270) – The concerns of acid rain vary across the globe.  Many countries in North America and Europe have websites dealing with acid rain.  Search to locate one or use the links provided at the textbook’s website.  What are the issues in the country you selected?  Does the acid deposition originate outside the borders of the country?

3.  Chapter 6, Question 25 (page 278) – Assuming the ocean continues to acidify at the same rate that it has been over the past 200 years, how long will it take before the ocean actually becomes acidic?  What are some possible affects of this?   What do you think is the appropriate response?

4.  Chapter 6, Question 49 (page 280) – Discuss the validity of the statement, “Photochemical smog is a local issue, acid rain is a regional one, and the enhanced greenhouse effect is a global one.”  Briefly describe the chemistry behind each issue.  Do you agree that the magnitudes of the problem are really so different in scope?  What do you think are the appropriate responses to each issue?
