WebHistory of Carbon Modifications Charcoal: Charcoal results when (dry) wood is heated to at least 275 o C (527 o F) in an oxygen-free environment. The wood then can't burn or oxidize with the basic reaction C + O 2 ® CO 2 but pyrolyzes to carbon (in the form of charcoal) and various gases. Pyrolysis is the fancy word for "thermochemical decomposition of stuff" or … WebCarbon (pronounced as KAR-ben) is a soft nonmetal denoted by the chemical symbol C. It forms several allotropes including diamond, graphite, graphene, and fullerene. Carbon is the sixth most abundant element in the earth’s crust, and it can be obtained in the form of black powder by burning organic compounds in a limited supply of oxygen [1].
