**Average Composition of the Atmosphere up to an Altitude of 25 km** | Gas Name | Chemical Formula | Percent Volume | |-----------------|------------------|----------------| | Nitrogen | N₂ | 78.08% | | Oxygen | O₂ | 20.95% | | Water | H₂O | 4% | | Argon | Ar | 0.93% | | Carbon Dioxide | CO₂ | 0.036% | | Neon | Ne | 0.0018% | | Helium | He | 0.0005% | | Methane | CH₄ | 0.00017% | | Hydrogen | H₂ | 0.00005% | | Nitrous Oxide | N₂O | 0.00003% | | Ozone | O₃ | 0.000004% | **Questions:** 4. Under STP conditions, compare the relative rates at which Earth’s atmospheric gases diffuse through a common orifice. List them in order of fastest to slowest to diffuse (WITH numeric proof!). 5. What is the partial pressure of carbon dioxide in Earth’s atmosphere? 6. What does the table of atmospheric gases tell you about the mole fraction of sulfur hexafluoride in the atmosphere? 7. What is the mole fraction of greenhouse gases in the atmosphere? (Please use the given table.) 8. We already broke down the sources of anthropogenic CO₂ in class. All SF₆ is anthropogenic. Not all CO₂ and CH₄ are anthropogenic. Do you believe human activity can change the partial pressure of CO₂ enough to make a difference? Why or why not? 9. What are you personally doing for the big beautiful world lately?
