Graphite, which is pure carbon, is the “lead” in pencils. Diamonds are carbon and so is charcoal. Some hard coals are up to 98% carbon. Carbon is also present in all living things. Forests, for example, are made almost entirely of carbon-containing compounds. Carbon and carbon compounds are widely used as raw materials in industrial products. Many plastics, detergents, foods, and medicines are made from carbon-containing compounds. The oil, coal, and natural gas we burn for energy are made up mostly of carbon. Our dependence on these fuels has, in recent years, caused economic problems, but even more importantly, it has contributed to the worldwide problem of global warming. Most scientists now believe that the burning of carbonbased fuels has increased the concentration of carbon dioxide in the atmosphere, and that this, in turn, has resulted in rising C 1 16450_EC_CarbonChem_all_4p.e.ind1 1 10/21/08 2:33:32 PM 2 CARBON CHEMISTRY Figure 1.1 A diamond is made up entirely of carbon atoms arrange
