WebGraphite consists of a ring of six carbon atoms closely bonded together hexagonally in widely spaced layers. The bonds within the layers are strong but the bonds between the layers are less in number and therefore are … WebQuestion: Make a table with title (Minerals) and make columns with the properties (color, luster, streak, hardness, specific gravity, cleavage and fracture) for the following minerals, in the order listed below. Also be sure to list 3 or more "uses" for each of these specific minerals (for example: pencil lead, plaster board, surgical cutting tools, auto body

WebGraphite is prized for both its strength and weakness. The covalent bonds within graphite’s sheets are very strong and graphite has a relatively low specific gravity. If graphite is … Graphite is a mineral that forms when carbon is subjected to heat and pressure in Earth's crust and in the upper mantle. Pressures in the range of 75,000 pounds per square inch and temperatures in the range of 750 degrees Celsius are needed to produce graphite. These correspond to the granulite … See more Most of the graphite seen at Earth's surface today was formed at convergent plate boundaries where organic-rich shales and limestones were subjected to the heat and pressure of regional metamorphism. This … See more Graphite and diamond are the two mineral forms of carbon. Diamond forms in the mantle under extreme heat and pressure.
