Answer to Question 1

We keep the hydrogens in order to keep track of what's happening overall in the
reaction. It could be important to know that water is being formed. If we are just interested

Answer to Question 2

They affect temperatures. The sulfate aerosols released by burning coal tend to
counteract the additional carbon dioxide emitted, though the presence of the aerosols is
fleeting (several weeks' residence time) and the presence of carbon dioxide lasting. As
pointed out on p. 373, GCMs that do not include aerosol effects fail to reproduce the correct
interhemispheric temperatures. Aerosols are connected to the cloudiness experienced. It is
thought that the presence of aerosols has led to increased cloudiness in the Northern
Hemisphere.
