a) The three formulas below represent combustion of three different fossil fuels.
Label each with the fossil fuel that they represent.
C+ O2 -----> CO2 + heat
Ch4 + 2O2 ----> CO2 + 2H2O + Heat
C8H18 + 12.502 ----> 8CO2 + 9H2O + Heat
(b) Examine the combustion formula above that corresponds to coal. Then explain in words how it is that burning one ton of coal can release more than three tons of carbon dioxide into the atmosphere, depending on the purity of the coal.
