Your Ad Here	Cerium fluoride CeF3, white hexagonal crystals, melting point 1460°C, used in arc carbons to increase the brilliance of carbon-arc lamps. Cerussite an ore of lead consisting of lead carbonate, PbCO3. It forms well-shaped orthorhombic crystals. Chemical reaction a permanent change in which the new substance formed has new properties. The change is accompanied by evolution or absorption of heat or light or by change of colour etc., e.g., burning of paper.
Cesium bromide CsBr, a colourless, crystalline powder with a melting point of 636°C; soluble in water; used in medicine, for infrared spectroscopy, and in scintillation counters. Cesium carbonate Cs2CO3, a white, hygroscopic, crystalline powder, soluble in water; used in speciality glasses.
Cesium chloride CsCl, colourless cuboid crystals, melting point 646°C; used in filaments of radio tubes to increase sensitivity, in photoelectric cells, and for photosensitive deposit on cathodes. Cesium fluoride CsF, toxic, irritating, deliquescent crystals with a melting point of 682°C; soluble in water and methanol; used in medicine, mineral water, and brewing Cesium hydroxide CsOH, colourless or yellow, fused crystalline mass with a melting point of 273.3°C; soluble in water; used as electrolyte in alkaline storage batteries at subzero temperatures.

Cesium iodide. Csl, a colourless, deliquescent, crystalline powder with a melting point of 621°C; soluble in water and alcohol; crystals used for infrared spectroscopy. Cesium perchlorate CsCIO4, a crystalline solid with a melting point of 250°C; soluble in water; used in optics and for speciality glasses.
Your Ad Here	Cesium sulphate Cs2SO4, colourless crystals with a melting point of 1010°C; soluble in water; used for brewing and in mineral waters. Chemical bond a link between atoms that leads to an aggregate of sufficient stability to be regarded as an independent molecular species. Chemical bonds in clued covalent bonds, electrovalent (ionic) bonds, coordinate bonds, and metallic bonds. Hydrogen bonds and Vander Waals force are not usually regarded as true chemical bonds.

Chemical dating
refers to an absolute dating technique that depends on measuring the chemical composition of a specimen. Chemical dating can be used when the specimen has been known to undergo slow chemical change at a known rate. For instance, phosphate in buried bones is slowly replaced by fluoride ions from the ground water. Measurement of the proportion of fluorine present gives a rough estimate of the time that the bones have been in the ground. Another, more accurate method depends on the fact that amino acids in living organisms have been L-optical isomers. After death, these racemize and the age of bones could be estimated by measuring the relative amounts of D- and L-amino acids present.

Chemical energy
the part of energy stored within an atom or molecule that can be released by a chemical reaction
