Why Neither N2 Nor O2 Are Greenhouse Gases
Quiz 6 Key
1. Neither N2 nor O2 are greenhouse gases because
A. N2 and O2 react with one another, producing N2O2 when exposed to infrared radiation.
B. their overall electric charge distribution does not change when they vibrate.
C. infrared radiation causes their bonds to break.
D. their atmospheric concentrations are not changed by human activity. Remember that greenhouse gases have a change in bond structure when interacting with infrared radiation.
2. Find the molar mass of ethanol, C2H6O. A. 29.02 g/mol B. 45.06 g/mol C. 46.07 g/mol D. 110.0 g/mol 3. How many atoms are present in 0.375 mol of palladium (Pd) atoms? A. 1.61 1024 B. 6.02 1023 C. 2.26 1023 D. 2.12 1021 Remember that one mole is 6.02 x 1023 …show more content…
Methane is approximately 23 times more powerful than carbon dioxide as a greenhouse gas. Which are significant sources of methane emissions? I. The digestive systems of ruminants (cows, sheep, etc.) II. Automobile exhaust III. Rice cultivation IV. Decaying wetland vegetation A. I only B. I and II only C. II only D. I, III, and IV only Remember that there are several sources of methane. 11. What factors are considered in determining the global warming potential for a particular molecule? I. Relative contribution of a molecule of gas to global warming II. Lifetime in the atmosphere III. Atmospheric concentration A. I only B. I and II only C. I and III only D. II and III only Remember that the GWP represents the relative contribution of one molecule of the atmospheric gas to global warming.
12. Land use changes have a big impact on global warming because of their effect on albedo. Albedo A. is the primary wave number at which a greenhouse gas absorbs infrared radiation. B. describes the effectiveness of a molecule as a greenhouse gas. C. is the ratio of electromagnetic radiation reflected by a surface to the amount of radiation hitting that surface. D. describes the tendency of an atmospheric molecule to react with other atmospheric molecules, reducing their global atmospheric lifetimes. Remember that is very influential when examining how much heat the earth
