Nitrogen dioxide (NO2) is the only important gaseous species in the lower atmosphere that absorbs visible light.
(a) Write the Lewis structure(s) for NO2.
(b) How does this structure account for the fact that NO2 dimerizes to form N2O4? Based on what you can find about this dimerization reaction in the text, would you expect to find the NO2 that forms in an urban environment to be in the form of dimer? Explain.
(c) What would you expect as products, if any, for the reaction of NO2 with CO?
(d) Would you expect NO2 generated in an urban environment to migrate to the stratosphere? Explain.
During a routine check of the fluoride content of Gotham City\'s water supply, the following results were obtained from replicate analyses of a single sample: 0.511 mg/L, 0.487 mg/L, 0.511 mg/L, 0.487 mg/L, and 0.519 mg/L Determine the mean and 90..
