In fact, since at least as far back as Aristotle, the basic formula for comedy has had more to do with conventions and expectations of plot and character than with a requirement for lewd jokes or cartoonish pratfalls. In essence: A comedy is a story of the rise in fortune of a sympathetic central character.
The Acid Rain Problem. Carbon dioxide in the air can dissolve in rain water to form carbonic acid, H 2 CO 3. CO 2 + H 2 O H 2 CO 3. Carbonic acid is a weak acid. It partially ionises to form hydrogen ions. H 2 CO 3 H + + HCO 3 -. The hydrogen ions from carbonic acid give natural rain water a slightly acid pH value of 5.6.
It is however one of the main contributors to acid rain and sulphur dioxide dissolves in rain water to form sulphurous acid. The main greenhouse gases are carbon â¦ dioxide, methane and nitrogen oxides (which also causes acid rain). Nitrogen oxide is a small percentage greenhouse gas (approx 6-7%) but is still significant because it is about 300 times more potent that carbon dioxide at 'trapping' solar radiation.
