Type of bonding indysingh03 https://padlet.com/indysingh03/mk34h8aoat86/wish/174412771 Graphite is made of pure carbon atoms. The bond between the C atoms is called a covalent bond. A covalent bond is a type of chemical bond in which the electron pairs are known as shared pairs or bonding pairs. Covalent bonding can also be called molecular bonding.]]> 2017-05-30 13:45:53 UTC https://padlet.com/indysingh03/mk34h8aoat86/wish/174412771 7. Historical Background indysingh03 https://padlet.com/indysingh03/mk34h8aoat86/wish/174415876 Graphite was first discovered in Cumbria in North England at the beginning of the sixteenth century. It is not known who discovered Graphite itself, but who discovered its uses.]]> 2017-05-30 13:57:13 UTC https://padlet.com/indysingh03/mk34h8aoat86/wish/174415876 8. Interesting or unusual past uses indysingh03 https://padlet.com/indysingh03/mk34h8aoat86/wish/174416675 In the 1500's after graphite was found, locals found it useful to mark sheep with it. Now it can be used to make baseball bats (mixed with other materials). And it is also used in the Aerospace department for nozzles on aircraft.]]> 2017-05-30 14:00:24 UTC https://padlet.com/indysingh03/mk34h8aoat86/wish/174416675 9. Uses and importance indysingh03 https://padlet.com/indysingh03/mk34h8aoat86/wish/174417683 Graphite was given its name by a German scientist. The name is derived from a Greek word graphein which means to write. So it's main and most important use is for making the lead used in pencils.]]> 2017-05-30 14:04:23 UTC https://padlet.com/indysingh03/mk34h8aoat86/wish/174417683 11. How is the compound obtained, and made? indysingh03 https://padlet.com/indysingh03/mk34h8aoat86/wish/174519180 Open pit mining involves extracting rock or minerals from an open pit or burrow. Open pit methods are used when the ore is close to the earth and the surface material covering the deposit is thin. Quarrying is a form of surface mining employed to obtain graphite by breaking the rocks either by drilling or by using dynamite explosives to cut open the rocks and compressed air or water to split it. Graphite most often occurs in metamorphic rocks formed from regional metamorphism or contact metamorphism of organic-rich sedimentary rocks, such as organic-rich marble, quartzite, schist, gneiss, and metamorphosed coal. ]]> 2017-05-30 23:35:11 UTC https://padlet.com/indysingh03/mk34h8aoat86/wish/174519180 3.

Chemical Properties of Graphite indysingh03 https://padlet.com/indysingh03/mk34h8aoat86/wish/174523046
  • Graphite is chemically inert to almost all chemicals.
  • It burns completely when heated in oxygen to form carbon dioxide. However, it fails to burn in air, even if it is heated to high temperatures.
  • When heated in the presence of concentrated sulfuric acid and potassium dichromate, graphite gets oxidized to carbon dioxide.
  • Due to its chemical inertness and stability at high temperatures, it is widely used as a refractory material.
