WebCarbon occurs in all known organic life and is the basis of organic chemistry. When united with hydrogen, it forms various hydrocarbons that are important to industry as refrigerants, lubricants, solvents, as chemical feedstock for the manufacture of plastics and petrochemicals, and as fossil fuels. WebApr 10, 2024 · Perhaps the best-known mechanism of ocean carbon sequestration is the biological gravitation pump (BGP), which, as the name suggests, is the sinking of biological debris vertically down the water column into the ocean’s interior. Bits of zooplankton fecal matter, pieces of phytoplankton, dead microorganisms and such aggregate into clumps …

WebDiamond is probably the most well known carbon allotrope. The carbon atoms are arranged in a lattice, which is a variation of the face-centered cubic crystal structure. It has superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. Each carbon atom in a diamond is covalently bonded to four ... WebNicknamed buckyballs, this first known stable molecular form of carbon not only opened up a new field of organic chemistry but also, through the development of carbon nanotubes, a new field of materials science. In 1996, Robert Curl, Harold Kroto, and Richard Smalley won the Nobel Prize in Chemistry for the discovery of the fullerenes. pe + interp rfx ife s
