Question | Answer |
1. Define catalyst | A substance that increases the rate of a chemical reaction by lowering the amount of energy needed for the reaction. |
2. Examples of catalysts found in a catalytic converter. | Usually a metal. Platinum, Palladium, Rhodium. Ceramic pellets coated with these metals are found in a catalytic converter. |
3. Why is a catalytic converter a necessary piece of equipment on a vehicle? | Reduces the amount of pollutants released into the air. Removes Carbon Monoxide, nitrogen oxides & VOCS. |
4. True or False: When a catalyst is used in a chemical reaction, the amount of the catalyst at the start is the same as the end. | TRUE or FALSE |
5. How do power plants work to control pollutants emitted into the atmosphere? Use the terms "Scrubber", "Lime", "Water" and "Sulfur Dioxide." | 5. REFER TO STUDY GUIDE! |
6. Thinking back to the activity we did with Hydrogen Peroxide (H2O2) and Manganese Dioxide, why did we add a scoop of manganese to the test tube? | To see a chemical reaction that caused it to turn black, fizzle & heat up. |
7. Renewable energy example. | Solar Energy |
7. Renewable energy example. | Nuclear Energy |
7. Renewable energy example. | Wind Energy |
7. Renewable energy example. | Geothermal Energy (Earths Heat) |
7. Nonrenewable energy example. | Oil |
7. Nonrenewable energy example. | Coal |
7. Nonrenewable energy example. | Natural Gas |
7. Nonrenewable energy example. | Metallic Ore |
8. What is the difference between renewable and nonrenewable resources? | Renewable: Energy that can be replaced by new growth - EX: SOLAR. Non Renewable: Limited amounts. When they are used up, they are gone forever. Ex: Oil, Natural Gas. |
9. Describe the trend in the legislation & regulation of air pollution over time. (How did the laws change over time?) | 1955 - "Air Pollution control act" - provided $ to study Air Pollution. 1962- "Clean Air Act" passed by congress to reduce Air Poll. 1970- Clean Air Act Government wrote laws to limit Air Pollution. 1971- EPA - Oversees the study & Control of air poll |
10. How does an "ECONOMIST" investigate how to reduce air pollution? | Calculates the cost to put pollution control measures into effect. |
10. How does a "POLITICIAN" investigate how to reduce air pollution? | Enacts the laws & government agencies write the rules that tell manufacturers how to manage air pollution. |
10. How does a "PUBLIC POLICY EXPERT" investigate how to reduce air pollution? | Weigh the costs & benefits of controlling pollution & make recommendations on which ones are most needed & cost effective. |
11. How has the air quality in Los Angeles changed over the last 50 years? | Laws were passed to control pollution (no back yard burning, emissions for cars/trucks, rules for school bus idling). Ozone & Smog has been reduced in L.A. |
12. What has caused the change in L.A.'s air quality? | Monitoring & Controlling pollution has caused LA's OZONE & SMOG problems to improve. Laws were passed to control pollution (no back yard burning, emissions for cars/trucks, rules for school bus idling. |
13. How has the air quality in the Adirondacks changed? | Has improved slowly over the past 20-30 years. |
14. What has caused the change in air quality in the Adirondacks? | The "Clean Air Act" and many other laws were passed to improve air pollution. Also, coal burning power plants in the Midwest are forced to reduce the release of NOX, SO2 & Mercury. |
15. Convince you Grandmother why it's important to buy & us compact fluorescent light bulbs and not incandescent light bulbs? SUPPORT YOUR ANSWER with a MINIMUM of 2 facts from the book!!! | Fluorescent lights use much less electricity than incandescent lights. They use only 1/4 of the electricity of a normal bulb and last 10 times longer and reduce the amount of CO2. |
16. Choose two of the following energy sources, and compare/contrast them by giving the ADVANTAGES and DISADVANTAGES of each. SOURCES: Natural Gas, nuclear fuels, biofuels, hydrogen. | 16. REFER TO STUDY GUIDE! |
