We will put the enemy: lost the fight. Grade nine chemistry sixth unit review outline [carbon and carbon oxides] Topic 1 Diamond, graphite and C60 A carbon, elemental diamond, graphite and C60 are composed of carbon element, but the structure of the carbon atoms arranged in different ways, so their properties differ, but the nature of the differences and cause them to have different purposes. Thus, in the study, we should understand the relationship between the structure, nature and use of the material, that is, the structure determines the nature, the nature determines the use; in turn, the use reflects the nature, and the nature reflects the structure. Please read the following examples [1] two pieces of information, and then answer the question. 1. diamond, graphite and C60 comparison of the diamond structure, conductive state uses color melting thermal conductivity 2. hardness of amorphous carbon, the main physical properties of the category structure of charcoal, activated carbon material uses mixture (composed of tiny crystals of graphite and a small amount of impurities) porous adsorption (adsorption of activated carbon in the presence of solid charcoal) to smell, gas adsorption and decolorization is eight shape almost non-conductive natural hard material, knife, drill the decor colorless and transparent not a high thermal conductivity of graphite layered thin flake solid soft electrode, pencil, lubricant flake high temperature resistance, good [example] 1 (1) please find out the material structure determines the nature of the two examples; (2) please find two examples of the material determines the nature of its use; (3) ask you to cite a fact of life, the nature of th
