Review Constants enodic Table In 1986 an electrical power plant in Taylorsville, Georgia, burned 8,376,726 tons of coal, a national record at that time. Coal is a fossil fuel made primarily of carbon, but it also contains sulfur among other elements. When carbon, C, burns in air, it reacts with oxygen, O2, to produce carbon dioxide,...
