Environmental Fact of the Day
A gallon of gasoline puts 19 pounds of carbon dioxide into the atmosphere. In California, passenger vehicles account for 40 percent of all greenhouse gas emissions.
Mass transit: A (relatively) easy way to limit your contribution to global warming.

One must wonder how a gallon of gasoline that weighs about 6.2-pounds can possibly put 19-pounds of cabon dioxide out of the exhaust pipe. Most of the carbon from a gasoline engine is in the monoxide form as well. From where does the additional mass come?
When gasoline burns (oxidizes) it adds 2 atoms of oxygen to each carbon atom producing carbon dioxide (CO2). The thirteen pound increase from the gasoline to CO2 is accounted for by the added oxygen atoms resulting from the combustion.
