5 Multiple choice questions
- caused by sulfuric and nitric acids resulting in lowered pH of surface waters
- S + O₂ → SO₂
2SO₂+ O₂ → 2SO₃
SO₃+ H₂O → H₂SO₄, natural source: volcanoes, decay of organic matter. man made source: combustion of sulfur containing coal and smelting of sulfide ores. methods of reduction: alkaline scrubbing.
- According to the EPA, mobile sources produce nearly half of two major causes of smog—volatile organic compounds (VOCs) and nitrogen oxides (NOx), almost 90% of carbon monoxide, and more than half of hazardous air pollutants.
- the lowest atmospheric layer
- was generally formed under freshwater conditions
5 True/False questions
baghouse filter → An instillation containing thousands of heat-resistant fiberglass bags to control particulate emissions. A baghouse works as a room size vacuum cleaner
photochemical smog → a brownish haze that is a mixture of ozone and other chemicals, formed when pollutants react with each other in the presence of sunlight
indoor air pollution → Compounds that affect breathing that occur indoors. Examples: woodstove smoke, furnace emissions, formaldehyde, radon, household chemicals
carbon dioxide → (CO) Sources include incomplete combustion of fossil fuels. Effects: binds to hemoglobin reducing bloods ability to carry O2. Reduction accomplished by catalytic converters, oxygenated fuel, mass transit (reduction).
alveoli → a form of oxygen that has three oxygen atoms in each molecule instead of two. protects us from dangerous ultraviolet radiation from the sun
