- n. A naturally abundant nonmetallic element that occurs in many inorganic and in all organic compounds, exists freely as graphite and diamond and as a constituent of coal, limestone, and petroleum, and is capable of chemical self-bonding to form an enormous number of chemically, biologically, and commercially important molecules. Atomic number 6; atomic weight 12.011; sublimation point above 3,500°C; boiling point 4,827°C; specific gravity of amorphous carbon 1.8 to 2.1, of diamond 3.15 to 3.53, of graphite 1.9 to 2.3; valence 2, 3, 4. See Table at element.
- n. A sheet of carbon paper.
- n. A carbon copy.
- n. Electricity Either of two rods through which current flows to form an arc, as in lighting or welding.
- n. Electricity A carbonaceous electrode in an electric cell.

- n. An elementary substance, not metallic in its nature, which is present in all organic compounds. Atomic weight 11.97. Symbol C. it is combustible, and forms the base of lampblack and charcoal, and enters largely into mineral coals. In its pure crystallized state it constitutes the diamond, the hardest of known substances, occuring in monometric crystals like the octahedron, etc. Another modification is graphite, or blacklead, and in this it is soft, and occurs in hexagonal prisms or tables. When united with oxygen it forms carbon dioxide, commonly called carbonic acid, or carbonic oxide, according to the proportions of the oxygen; when united with hydrogen, it forms various compounds called hydrocarbons. Compare diamond, and graphite.
- n. A carbon rod or pencil used in an arc lamp; also, a plate or piece of carbon used as one of the elements of a voltaic battery.
- n. a sheet of carbon paper.
- n. a carbon copy.
from The Century Dictionary and Cyclopedia
- To put carbons in (an arc lamp).
- n. Chemical symbol, C; atomic weight, 11.97. An element found in nature in two distinct forms: the diamond, which is extremely hard, of high specific gravity (3.5), usually colorless and transparent, with brilliant adamantine luster, and crystallizes in octahedrons; and graphite, which is very soft, of low specific gravity , black and opaque, with metallic luster, and crystallizes in hexagonal plates. See diamond and graphite.
- n. The form of the diamond generally called carbonado; the black diamond.
- n. In electric lighting, a carbon-point (see below).

- n. an abundant nonmetallic tetravalent element occurring in three allotropic forms: amorphous carbon and graphite and diamond; occurs in all organic compounds
- n. a thin paper coated on one side with a dark waxy substance (often containing carbon); used to transfer characters from the original to an under sheet of paper
Methods of extraction 1) by heat alone: thermal decomposition silver oxide sliver + oxygen 2) by heating with carbon copper +carbon copper + carbon oxide dioxide
But is there any way to just toss away the term carbon tax and replace it with the carbon dioxide credit program, where 100% of the credit collected by the government would be returned to the taxpayer?
The term carbon equivalent is used because very often, there are other greenhouse gases involved other than carbon dioxide.
In this case, the heat has caused the carbon to unite with the element oxygen which exists in the air in the form of a gas, and a chemical compound is formed which we call carbon dioxid.
"In return for that, we get the right to sell what we call a carbon offset," explains Falls, based on the carbon the growing forest will lock in for a century or more.
They are looking at what I call the carbon DNA, so they benchmark it.
Chinese government announced Thursday that it had set a target to reduce greenhouse China is aiming to reduce what it calls carbon intensity by 40 to 45 percent compared with
Pretty much everything we humans do has some carbon cost, contributing to what we call our carbon footprint.
Most of the public do not really think about the fact that 'carbon' is shorthand for CO2 and so are tricked, at least subconsiously, into accepting the sort of language Ms. Rose uses.
June 11th, 2008 7: 36 pm ET we need al gore like we need more taxes this is outer limits we know you in power have run out of new ideas for new taxes but can you somehow come up with a new tax yes call it carbon credits or a tax by any other name it is sill a tax and will cost us the suckers who vote for this scam we need al gore like we need the black death again thanks for your misinfo mike h.
