Carbon element has 6 protons, 6 neutrons and 6 electrons. Carbon is widely existed in the atmosphere as CO2
and in the organic compounds.
The increase of Carbon Dioxide CO2 concentration in the atmosphere has been considered the main factor causing global warming.
CO32- is the most common Carbon ion.
» Common Carbon compounds:
• Carbon Dioxide, CO2
• Carbonic Acid, H2CO3
• Carbon Monoxide, CO
• Carbon Disulfide, CS2
• Carbon Tetrafluoride, CF4
• Carbon Tetrachloride, CCl4
• Magnesium Carbide, Mg2C
• Ammonium Carbide, (NH4)4C
• Boron Carbide, B4C
• Calcium Carbide, CaC2
» Carbon is also one of the most common element of organic compounds.
• Ethane, C2H6
• Acetic Acid, CH3COOH
• Propanol, C3H7OH
• Butane, C4H10
Example Reactions:
• 2Mg + CO2 = 2MgO + C
• 2Cu2O + C = 4Cu + CO2
• SiC + 2Cl2 = SiCl4 + C
• MnO2 + C = Mn + CO2
• C + 2H2 = CH4
• 2FeO + C = 2Fe + CO2
• 2CO + Ba(OH)2 = BaCO3↓ + C + H2O
• 2CuO + C = CO2 + 2Cu
• 3Fe2O3 + C = 2Fe3O4 + CO
• C + 2H2SO4 = CO2 + 2SO2 + 2H2O
