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.
Yes, most definitely! Acid rain is the acidification of water, which is caused when toxins such as carbon dioxide and sulphur dioxide (which are released by burning fossil fuels) react chemically with the water to lower the pH and create carbonic or sulphuric acid.ulphur is an impurity in fossil fuels (coal, oil and natural gas).  When they are burnt sulphur dioxide is produced and released into  the atmosphere. This mixes with water â¦ vapour and rain to produce  acid rain.
