1) Research any TWO of the following environmental issues: how gases contribute to global climate change, how pollutants cause acid rain, any specific water pollution issue, wastewater treatment, atmospheric ozone depletion, fossil fuel combustion and emissions, electricity production from nuclear power, photovoltaic energy. Explain the chemistry behind the issue (make sure to include at least two different vocabulary terms for each issue (for a total of 4) and underline them). Explain how an understanding of chemistry is essential for understanding the issue. How does your description of each issue demonstrate the first law of thermodynamics? How does your description of each issue demonstrate the second law of thermodynamics?
