Atmospheric Chemistry

Question 1

What are background gases?

Answer 1

‘natural’ gases of ratios similar to that of remote areas far away from anthropogenic activity.

Question 2

How is oxidisation identified within a reaction?

Answer 2

The loss of hydrogen from a compound.

Question 3

How is reduction identified within a reaction?

Answer 3

The reduction of oxygen and/or the increase of hydrogen atoms.

Question 4

What are the three kinds of process identified for sources and sinks of these gases?

Answer 4

Natural emissions from the earth (volcanic, oceans, animal waste, biological activity etc.), chemical transformations within the atmosphere and sinks: wet or dry deposition on the surface.

Question 5

What oxygen molecule makes up the Ozone?

Answer 5

O₃

Question 6

Finish the line: the shorter the wavelength (λ) of electromagnetic radiation, the higher the…

Answer 6

energy of the assosicated photon.

Question 8

Whats the difference between dry deposition and wet deposition?

Answer 8

Dry deposition is the direct deposit of acidic molecules (sulphuric acid) on biological organism or water and soil.

Wet deposition is when a soluable acidic molecule (sulphuric acid) is dissolved into water; rain, snow etc.
