Carbon

Science / Chemistry / Carbon: An element with atomic number 6. Carbon is a nonmetal found in all organic compounds. Carbon occurs naturally as diamond, graphite, and buckminsterfullerene.

Carbons

Health / Dentistry / Carbons: Vitreous (polycrystalline or glassy) or pyrolytic graphitic structures of relatively hard, inert, and stable compounds that are conductors of thermal and electrical energy. Characterized by ionic and MORE

Carbonate Hardness

Science / Chemistry / Carbonate Hardness: Water hardness due to the presence of calcium and magnesium carbonates and bicarbonates. The 'noncarbonate hardness' is due mostly to calcium and magnesium sulfates, chlorides, and nitrates. MORE

Carbonate Rock

Science / Geology / Carbonate Rock: A rock made up primarily of carbonate minerals (minerals containing the CO3 anionic structure). Limestone (made up primarily of calicite - CaCO3) and dolostone (made up primarily of dolomite - CaMg (C MORE

Carbonic Acid

Science / Geology / Carbonic Acid: A weak acid (H2CO3) that forms from the reaction of water and carbon dioxide. Most rain water is a very weak carbonic acid solution formed by the reaction of rain with small amounts of carbon dioxide MORE

Iron-Carbon Phase Diagram

Business / Machine Shop / Iron-Carbon Phase Diagram: A graphical means of identifying different structures of steel and percentages of carbon occurring in steel at various temperatures. MORE

Radiocarbon Technique

Science / Marine Biology / Radiocarbon Technique: The estimation of primary productivity by the measurement of radiocarbon uptake MORE
