How do dirty fuels cause air pollution and what pollutants would be of Interest to you?
Step by step
Solved in 2 steps with 1 images
- Does it seem logical that the burning of fossil fuels and the addition of carbon dioxide to the atmosphere leads to the warming of the Earth? Why or why not?If gasoline produces only carbon dioxide and water when it burns completely, why is automobile exhaust a source of air pollution? List the pollutants formed and briefly describe their impact.Much of the U.S. electricity is generated in thermal generating stations that burn fossil fuels such as coal and natural gas. The use of solar-powered generating stations is expected to increase over the next decade and replace older fossil-fuel generating stations. What impact might this change have on greenhouse gas emissions?
- Explain how the choices consumers make can help limit greenhouse gas emissions and therefore offset the effects of climate change.The U.S. is one of several countries committed to reaching “net-zero” carbon emissions by 2050. This means that by 2050, all carbon dioxide emissions must be matched by the amount of carbon dioxide removed from the air. Why is it essential for all countries in the world to meet carbon reduction commitments like thisHow many kg of CO2 are emitted from an automobile that completely combusts all the gasoline in its 13.9 gallon fuel tank? You may assume that gasoline is entirely octane, which has the following combustion equation: 2 C3H18 (1) + 25 O2 (g) → 16 CO2 (g) + 18 H20 (g) Useful information: 1 gallon = 3.7854 L. • This combustion occurs in excess O2. • The density of octane is p = 703 g/L. • The molar mass of CO, is 44.01 g/mol. • The molar mass of octane is 114.23 g/mol. Answer:
- Describe two ways that people can change their habits and choices to reduce their personal greenhouse gas emissions. In each case, be clear about how the change reduces emissions.2: Write all the chemical reactions involved in the thinning of ozone layer from the reaction between chlorofluorocarbon (CFC) and ozone layer(O3).Explain how ozone in the upper atmosphere functions to filter short-wavelength solar radiation, and how chlorofluorocarbons (CFCs) cause depletion of the ozone layer?
- How many kg of CO2 are emitted from an automobile that completely combusts all the gasoline in its 16.5 gallon fuel tank? You may assume that gasoline is entirely octane, which has the following combustion equation: 2 C3H18 (1) + 25 O2 (g) → 16 CO2 (g) + 18 H20 (g) Useful information: • 1 gallon = 3.7854 L. • This combustion occurs in excess O2. • The density of octane is p =703 g/L. • The molar mass of CO2 is 44.01 g/mol. • The molar mass of octane is 114.23 g/mol.Without naturally occurring greenhouse gases, Earth's average global temperature would be near 0°F (or -18°C) instead of the actual value of 59°F (15°C). How do atmospheric greenhouse gases warm Earth? Do not use the word “trapped” in your answer4. Photochemical smog is a type of air pollution in the troposphere of our planet produced when sunlight acts upon motor vehicle exhaust gases to form harmful substances such as ozone (O3). For example, nitrogen dioxide (NO2) reacts with atmospheric oxygen (O2) in the presence of light to produce ozone (O3) and nitrogen monoxide (NO).
