The train of reactions thereafter is similar to that which is described above. Salt An ionic compound made up of a cation and an anion. It is often produced in neutralizaion reactions. A systematic way of expressing a number in exponential notation. At The semimetals are positioned next to the diagonal line on the periodic table, between the metals , and the nonmetals .
Slaked lime is an important material in the control of air pollution.
It reacts with the SO 2 formed in the combustion of sulfur-containing coal. If a substance is shaken with two immisicible liquids, upon standing, the two layers will separate and the substance will be distributed between the two liquid layers. A greater concentration of the substance will be present in that solvent in which it is more soluble. Solvent extraction is an industrial method of removing impurities from liquids and in separating pure metals from their ores. Spectroscopy Spectroscopy is a branch of analytical chemistry devoted to the determination of structure of atoms and the chemical composition of molecules by measuring the radiant energy they absorb or emit in any of the wavelengths of the electromagnetic spectrum .
