That depends on what you mean; Carbon is found in its pure form as graphite (pensil lead) and diamond.  It is a major component of coal, and a fairly large amount of every living organism on the planet.  For experiments using carbon (like production on nanotubes), pure carbon monoxide gas is typically used in a high-energy environment (like high power lasers, plasma gas, etc).  The carbon dioxide (CO) is produced from iron pentacarbonyl (Fe(CO)5).

If you are doing it in a laboratory setting, you can mix it with carbon and reduce it to the metal. You will need high temperatures, though.

Werehunt's answer is a bit confusing. It is possible to make real diamonds ( made out of carbon ) in the laboratory, both industrial quality diamonds and gem quality diamonds. \n\nIndustrial quality diamonds are made routinely in factories around the world, These are used in drilling bits and diamond saws etc. \n\nSome, gem quality diamonds have been made in the lab, but this is not done as a matter of routine.\n\nCubic zirconia is not a diamond ( not made of carbon ) but it can be cut and polished to shine like a diamond. \n\nColour in a diamond can be caused by imuprities or by distortions in its internal atomic lattice structure.

Carbon has made forms and can be used for several things.\n\nDiamond - Gemstone quality are cut and placed in jewelery, Industrial diamonds are used in tools like diamond tipped saws and drill bits designed to cut into heavy materials like stone or metal.\n\nWater Filters - Carbon can combine with many other elements which is why it is used to remove a number of impurities from drinking water and small aquariums.\n\nElectronics - Carbon is commonly used in electronic components (such as resistors) found in TVs, Radios, Computers, Playstations, etc.\n\nFeul & Energy - In the form of coal it is widely used in the boliers of electrical power plants to generate energy. In developing countries it is used as a more efficient means over wood for heating the home and cooking. In China the coal that is mined is pressed into round stackable bricks that are alloted to the people without electricity every month so they can cook food and heat their homes.\n\nGraphite - The "Pencil Lead" for wooden and mechanical pencils. A dry lubricant commonly used on small mechanical devices like locks and hobby motors of miniature vehicles.\n\nDrinks - By mixing with oxygen in the form of Carbon Dioxide it allows for the bubbles in soda.\n\nFood - In the form of baking soda (Sodium Bicarbonate) it creates gas bubble that make cookies and cakes light and airy.\n\nSteel - The strong and common alloy is made by adding carbon to iron.\n\nSimple Calories - Carbon in one of the key elements in the sugars and starches that make up the carbohydrades in food. The subtances are typically plant-based in origin and are the easiest to breakdown into energy.\n\nNano Tubes - An experimental "artificial muscle" consisting of strong microscopic carbon structures that can flex and contract with electrical current.\n\nAerospace Engineering - New aircraft and spacecraft hulls are made of overlapping layers of woven carbon fiber material and heated resins. The combined layers are stronger and lighter than the traditional aluminum panals that make up older aircraft and space craft skins.

No. There is no carbon in water. You need glucose\n\nphotosysthesis\n6*CO2 + 6*H2O -> C6H12O6 + 6*O2\n\nThe glucose has the 6 carbon atoms you need for 6 CO2 molecules. \nC6H12O6 + 6*O2 -> 6*CO2 + 6*H2O

The answer is very basic. Start with chemical names.  Carbon dioxide is made from carbon and oxygen. Carbon is called C, and Oxygen is called O. If you have two atoms of O, and one atom of C, then you have Carbon dioxide. The shorthand notaion for this is CO2. Don't be afraid of chemical formulas, but bring yourself to be comfortable with them, so you don't freak when you have to do a problem like this:\n__H4C + __O4Fe---->__HCO + __Fe. (this is balancing equations, but they're easy, once you learn to decode what chemical equations are trying to tell you )\n\nOn this website, just look at the ones that are relevant:\nhttp://www.ukrocketry.co.uk/forum/index.php?s=e26325e497d951d76619a79a0ad64ae7&showtopic=381\n\n\n\n\n\nThis si a segment on this from my school textbook: (sorry, its kinda long)\nA molecule or compound consists of at least two atoms that are chemically bonded. The chemical formula of a molecule or compound states how many atoms of each element are in one of its molecules. This formula is similar to an algebraic formula in its use of symbols. The description of a compound with numbers and symbols is called a chemical formula. Some formulae can be quite complex.\n\nQuestions you may have are:\n\nWhat are chemical compounds? \nWhat is the numbering system in a chemical formula? \nHow do you designate complex compounds? \nThis lesson will explain the basics of chemical formulas. \n\nChemical compounds\nA molecule is the chemical combination of two or more atoms. They can be of the same element, such as in the oxygen molecule (O2) or different as in the water molecule (H2O)\n\nA compound is a molecule that is made up of at least two different elements. The water molecule is a compound. When atoms of different elements combine to form a compound, the result is a new substance that has different properties than the original elements. A good example is when the poisonous green chlorine gas is combined with the explosive metal sodium to form the white salt crystals we use in our food.\n\nThe study of Chemistry is mainly interested in the formation of chemical compounds, since there are so many possible combinations of elements.\n\nChemical formulas\nChemical formulas (or more correctly: formulae) are designations of molecules and compounds in shorthand notation, similar to that used in Algebra.\n\nElements can be written as abbreviations or in a shorthand notation. For example, He denotes helium, Fe denotes iron, and Cl denotes chlorine. A chemical formula is writing the elements of a compound, using their abbreviations.\n\nThe combination of two or more elements to form a molecule is designated by writing their abbreviations next to each other. For example carbon monoxide is written as CO. The order in which the elements are written is typically alphabetical, but there are a number of exceptions for historical reasons and to clarify the geometry of the molecule.\n\nIf there is more than one atom of a type in the molecule, the formula shows it by a small number after the symbol. For example, water is H2O, which means there are 2 atoms of hydrogen and one atom of oxygen in the molecule. Carbon dioxide is CO2, which means there is one atom of carbon and two atoms of oxygen in the molecule.\n\nTo show the number of molecules, a full sized number is located in front of the molecule. For example 4 molecules of carbon dioxide is designated as:\n\n4CO2\n\nThis means there are a total of 4 C atoms and 8 O atoms in the combination. A way to remember this—taken from Algebra—is to think of it as 4 x (CO2).\n\nComplex formulae\nJust as in Algebra, you can use parentheses to separate parts in a complex formula. One example is the formula for nitroglycerin, a highly explosive substance.\n\nC3H5(NO3)3\n\nThis formula shows that nitroglycerin consists of 3 atoms of C, 5 atoms of H and then 3 molecules of NO3. If the parentheses were not used, you might have a formula like:\n\nC3H5N3O9\n\nThe number of atoms for each el

You could use a catalyst to turn CO2 into a oxygenate.\n\nPlants would be the most efficient and cheapest way possible as far as I know. But plants won't just grow on mars, you would need to make the conditions suitable for plant life to survive. I think they were talking about man-made global warming to increase the atmosphere and warm it up for possible teraforming. \n\nAlso, there is water on mars already and why would you want it to rain carbon?

Not pure carbon in pure water, no.  Don't believe me, try sticking a pencil lead (graphite is pure carbon, not actually lead) into a glass of water and see if it dissolves.\n\nBut carbon will dissolve in some solutions.\n\nAs an aside, you think the guy above me might be trying too hard?  A more concise answer is usually preferable.

The answer is B.\n\nIn your beginning reaction CO2 + C --> CO, you have 2 carbons and 2 oxygens on the reactants side, and you have 1 carbon and 1 oxygen on the products side.\n\nIn order to make the equation balanced, you have to make sure there are the same number of each element on both sides of the equation.\n\nSo to make this chemical equation balanced all you have to do is put 2 as the coefficient of the CO on the products side, making the final equation:  CO2 + C --> 2CO\nThis will give you 2 carbons and 2 oxygens on both sides.

Carbon occurs in all organic life and is the basis of organic chemistry. This nonmetal also has the interesting chemical property of being able to bond with itself and a wide variety of other elements, forming nearly ten million known compounds. \n\nBecause of their unique properties, multi-carbon compounds exhibit extremely large variety and the range of application of organic compounds is enormous. They form the basis of or are important constituents of many products (paints, plastics, food, explosives, drugs, petrochemicals, and many others) and of course (apart from a very few exceptions) they form the basis of all life processes.\n\nThe different shapes and chemical reactivities of organic molecules provide an astonishing variety of functions, like those of enzyme catalysts in biochemical reactions of live systems. The autopropagating nature of these is what life is all about.\n\nBecause of the special properties of carbon, it is likely that life on other star systems will be found to be carbon-based, in spite of speculations about the possibility of substituting silicon, which lies just below carbon in the periodic table.

first of all carbon is not an organic compound it is an element. and different compounds made from carbon are included in class of organic compounds.\n\ncarbon has got atomic number 6. so its electronic configuration will be 1s2,2s2,2p2. so it contains 4 electrons in its outermost orbit, we know that there should be 8 electrons to complete the octet and make the element stable, so carbon can either gain 4 electrons or lose 4 electrons to become stable, but both requires very high amount of energy.\n\nso it goes for sharing of electrons. it has the special property of catenation, ie carbon-carbon long chain formation. no other element has such property, so carbon itself has forms such high number of compounds which not even formed by rest all elements together. so it has been given special branch of chemistry called organic chemistry while rest all elements are included in inorganic chemistry. so its versatile

Silicon carbide is not organic. It is, however, very hard. It is used on the edges of cutting tools because it wears better than steel.\n\nOther carbon compounds exist that are not organically derived such as calcium carbide (used to generate acetelyne gas by reaction with water), carbon disulfide, etc. See the Wikipedia reference for others.
