Power = Energy Time
Energy = Power x Time
100 W x 2000 hours = 2 x 105 Watt-hours
(Since Watts and Hours are multiplied the unit is a Watt-hour.)

Sulfur dioxide and nitric oxides can both react with water vapor in the atmosphere to produce acid compounds (sulfuric acid and nitric acid). Rain is normally weakly acidic because some of the carbon dioxide in the atmosphere also reacts with water vapor to form carbonic acid. But sulfur dioxide and nitric oxides result in rain with an even lower pH.

Dispersants – disperse (spread out) the substances. They do not chemically break down the substance.
Increased surface area may allow any microbes present that can break down the oil to be able to do so more quickly.
Term to know: Bioremediation = using a living thing to remedy (help solve) an environmental problem. If microbes that could break down oil were utilized this would be bioremediation.
