Calcium carbide forms flammable ethyn when it comes in contact with water and is therefore considered hazardous. Some environmental effects of water hardness include hardening of domestic equipment, because high temperatures cause carbonate hardness. This may dramatically decrease the lifespan of equipment, and causes an increase of domestic waste. Calcium carbonate interacts with detergents ...
Carbide Structure. In carbide structure, two carbon atoms are attached to each other with the three covalent bonds. From these three covalent bonds, two bonds are pibonds. These pibonds are formed by the lateral overlapping of the porbitals. Another bond is the sigma bond, which is formed by the headon overlapping of the sorbitals.

Answer (1 of 9): A pretty genuine doubt, even I had this doubt when I first saw this formula. The answer lies in the fact that carbon can form bond with other carbon atoms, I guess you can guess the answer now In calcium carbide the carbide ion is an acetylide ion (C2) .
Calcium Carbide Calcium carbide is a substance which is produced by an industrial process. The molecular formula of this is CaC2. After looking at this formula, one can easily figure out that one molecule of this consists of one atom of calcium and two atoms of carbon. Tungsten Carbide It appears to be grey in colour, which is like a fine powder. If you look at the molecular formula, you will ...
Boron carbide (B 4 C) has higher hardness than alumina or silicon carbide. Its oxidation product (B 2 O 3) provides a protective skin at high temperatures (> 800 o C). Because of its high hardness and wear resistance, boron carbide is applied in lowtemperature appliions such as grinding wheel dressers, and abrasive blast or water jet nozzles. Boron carbide is used in grit blasting nozzles ...
