Q. In what layer of the atmosphere is the ozone layer found?

Junge layer
Q. How many moles of charge does an aluminum ion have?

Q. Sulfur hexafluoride and CFC-11 both affect radiative forcing to the same degree. Why is sulfur hexafluoride's GWP five times greater than that of CFC-11?

Sulfur hexafluoride has a significantly shorter residence time than CFC-11.
Both compounds have similar residence times, but only sulfur hexafluoride absorbs infrared radiation.
Both compounds have similar residence times, but only CFC-11 absorbs infrared radiation.
Sulfur hexafluoride has a lifetime of 3200 years, while CFC-11 has a lifetime of 45 years
Both compounds have similar residence times, but only sulfur hexafluoride re-emits long wave radiation
Q. The environmental organization BFPFA (Beachfront Property For All) wants to decrease anthropogenic inputs to the greenhouse effect. Which of the following actions would not help them reach this goal?

Large scale planting of trees and decreasing the rate of deforestation
Increasing fuel efficiency standards for all new vehicles
Replacing HFCs with refrigerants that do not absorb IR radiation.
Decreasing the number of rice paddies
Removing OH from the atmosphere

Q. Your aunt's favorite color is blue. Her hydrangeas, however, didn't get the memo and had the audacity to be a rosy pink. What could you do to make her pink hydrangeas blue?

Increase the soil pH.
Add calcium carbonate to the soil.
Add aluminum to the soil.
Add an alkaline solution the soil.
Nothing, you can't change the color of a flower!
Q. Which of the following is an indirect greenhouse gas?

Q. Which statement about the sulfur cycle is true?

Sulfur compounds in the atmosphere have a short residence time due to oxidation reactions.
The atmosphere is the largest sulfur reservoir on earth.
The mean residence time for a sulfur molecule in the sea is 123 years.
Large volcanic eruptions increase global temperatures because they emit sulfur.
Sulfur found in the earth's crust comprises a minor portion of the earth's sulfur budget.
