what is carbon used for?

Carbon, the element, comes in three forms. These are graphite, diamond and the other (non christoline). Each is used in many ways for many things.\n\nGraphite is a flat form of carbon molecule. The cristles are hexagonal. These crystals can slide over each other acting as a lubricant. Graphite is used as a lupricant - often calles "graphite greese". It is also used in "lead" pencils.\n\nTetrahedron crystals are found in diamonds. These are not flat. These are used in jewelery, cutting tools, grinders etc. This is because diamonds are very hard and long lasting.\n\nNon crystaline carbon is used in chamical reactions. Coal is baked in baked in coke ovens to make "coke" (not the drink) which is then used in the manufacture of iron and steel.\n\nCardon is used, by plants, to make sugars, which it turn, we eat to give us energy. As our bodies "burn up" these sugars, we create carbon dioxide which we exhale.\n\nEverywhere you look you see uses of carbon - In timber, carbon fibre, Gasoline the list goes on and on.

Lithium is a metallic element commonly used in batteries for it's ability to produce electricity (I think the lithium does it), and carbon is an element both essential for life and a by-product of the chemical processes that make life work.

Carbon dioxide, because that is the raw material required for photosynthesis

carbon needs 4 bonds to be stable. if there is not enough stuff around to make single bonds, it will be double. and still be more reactive wanting just single bonds

Carbon is in the same family as lead, and it is the only element in that group that is in a period lower than 2.  So carbon is the only element fitting your requirement.

There are several theories as to what the best method for dealing with excess carbon dioxide in the atmosphere. The one that I like the best is to turn it into rock. Yes, rock. Ever seen the Grand Canyon? It is made up of carbonate rocks. Through "relatively" simple chemical reactions, scientists can mix carbon dioxide gas with catalysts and form it into rock. Another option is to seed the ocean with powdered iron to stimulate the growth of photosynthetic (use CO2 and give off oxygen)plankton. This is an incredibly powerful method, but is also risky because we don't really understand how this will affect the food chain of the oceans. \nLastly, there is a place in Canada that is pumping carbon dioxide into the chambers left over from oil drilling. The CO2 is compressed into a "supercritical" state, where it behaves like a dense liquid. As a bonus, the CO2 helps to "push out" the oil, making the pumping more efficient. Thousands of tons of carbon dioxide have already been sequestered at just this facility. There are also huge bodies of water underground, where millions of more tons of CO2 can be sequestered.For more info, search for "carbon dioxide sequestration", as that is a common scientinfic term for what you want to do.

In nature, small amounts of carbon disulfide are found in gases released to Earth's surface as, for example, in volcanic eruptions or over marshes. Commercial carbon disulfide is made by combining carbon and sulfur at very high temperatures.

in biology, the exchange of carbon between living organisms and the nonliving environment. Inorganic carbon dioxide in the atmosphere is converted by plants into simple carbohydrates, which are then used to produce more complex substances. Animals eat the plants and are then eaten by other animals. When these life forms die, they decay, breaking down into, among many other things, carbon dioxide, which returns to the atmosphere. Plants and animals also release carbon dioxide during respiration. Animals and some microorganisms require the carbon-containing substances from plants in order to produce energy and as a source of materials for many of their own biochemical reactions; this cycle is vital to them. The process of incorporating carbon dioxide into the molecules of living matter is called fixation. Nearly all carbon dioxide fixation is accomplished by means of photosynthesis, in which green plants form carbohydrates from carbon dioxide and water, using the energy of sunlight to drive the chemical reactions involved. Green plants use carbohydrates to build the other organic molecules that make up their cells, such as cellulose, fats, proteins, and nucleic acids. Some of these compounds require the incorporation of nitrogen (see nitrogen cycle). When carbohydrates are oxidized in cells they release the energy stored in their chemical bonds, and some of that energy is also used by the cell to drive other reactions. In the process of oxidation, or respiration, oxygen from the atmosphere (or from water) is combined with portions of the carbohydrate molecule, producing carbon dioxide and water, the compounds from which the carbohydrates were originally formed. However, not all of the carbon atoms incorporated by the plant can be returned to the atmosphere by its own respiration; some remain fixed in the organic materials that make up its cells. When the plant dies, its tissues are consumed by bacteria and other microorganisms, a process called decay. These microorganisms break down the organic molecules of the plant and use them for their own cell-building and energy needs; by their respiration more of the carbon is returned to the atmosphere. The carbon-containing molecules that an animal derives from consuming other organisms are reorganized to build its own cells or oxidized for energy by respiration, releasing carbon dioxide and water. When the animal dies it too is decayed by microorganisms, resulting in the return of more carbon to the atmosphere. Carbon-containing molecules in wood (or other dry, slow-decaying organic materials) may be oxidized by burning, or combustion, also producing carbon dioxide and water. Under conditions prevailing on earth at certain times, green plants have decayed only partially and have been transformed into fossil fuels–coal, peat, and oil. These materials are made of organic compounds formed by the plants; when burned, they too restore carbon dioxide to the atmosphere.

carbon is tetravalent (ie it is able to form bonds with 4 other atoms. It therefore can form backbones of more complex structures (see diamond and graphite). It is also found abundantly on earth.

The simplist way to make carbon is through imcomplete combustion of common fuels such as tissues ­of plants (wood), tar, oil, natural gas, etc. ­that will burn easily. When they burn, the compound is oxidised and carbon dioxide is produced. The remaining material is nearly pure carbon (which can be seen in the charred nature of burnt wood, for example).  \n\nIf you are wondering how extract C from CaCO3 however, it is little more involved.  Simply put: \n\n1.  React the CaCO3 with HCl to from for CO2 gas. \nCaCO3 + HCl ---> CO2 + H2O + CaCl2\n\n2.  From the CO2 gas from Step 1, react it with highly reactive metal such as Tungsten and it should produce tungsten trioxide with elemental carbon.\nCO2 + W  <---> WO3 + C\n\nIn theory it works but I dont know if it will work in real life.  Try it if you are so curious.  =)

People use the oxygen from the air and produce carbon dioxide. Trees use carbon dioxide and product oxygen. Trees also prevent erosion, provide many food products, provide shade and create an aestetically pleasing environment.

It's used in the building industry. It is also used in the making of metallurgical flux, fertilizers, fertilizer manufacture and in the chemical industry. Clear calcite crystals were used as prisms. Occasionally rough crystals are used in jewelry or as ornaments. If you have a nice one, you can have it as a mineral collection.
