Group 51 Group 51 Mr. Moody Chemistry 1211 01/10/10 Introduction One of the major problems we as humans face on our planet is the growing threat of CO 2 emissions into the atmosphere. When fossil fuels are burned, CO 2 gasses are released in the atmosphere where they destroy the ozone layer. In order to be able to fix this problem, we must understand how much CO 2 is being released so that we can determine how much is being absorbed naturally. We must compare the amount of CO 2 emitted to the amount that is naturally absorbed by plants and trees in photosynthesis to determine if plants and trees alone are capable of absorbing the excess CO 2 . In order to solve this problem by reducing the amount of CO 2 emitted into the atmosphere, we must find other uses for CO 2 , such as using it to produce chemicals. By researching the top chemicals that use CO 2 in their production, we can determine if this process is able to effectively reduce the harm done to the ozone layer because of the excess amounts of CO 2 . In order to further solve this problem, we must research other ways to use the excess CO 2 , in addition to the production of chemicals. By comparing the amount of CO 2 produced annually to the amount of CO 2 used in these other processes, we can determine whether those processes will significantly reduce the amount of CO 2 emitted into the atmosphere. Calculation To determine the Mass of CO 2 produced from the burning of fossil fuels we first found that Coal, Natural Gas, and Oil were the three major fossil fuels burned in a year. Coal To calculate the amount of CO 2 produced in a year by coal we first found the number of short tons burned a year. Next we turned that in to grams then used a measured amount of the average amount of carbon by mass of one gram of coal. We then used the equation to show that for every one mole of carbon in coal it will produce one mole of CO 2 and then the molar mass to convert moles to mass.
