the equilibrium constant, also known as K eq, is defined by the following expression: [Math Processing Error] K e q = [ C] c [ D] d [ A] a [ B] b. where [A] is the molar concentration of species A at equilibrium, and so forth. The coefficients a, b, c, and d in the chemical equation become exponents in the expression for K eq.

Barium is a soft, silvery, reactive metal. Because barium is so dense it is commonly used in some alloys, for example in spark plugs and ball bearings. As of 2013, China, India and Morocco were the world's largest producers of barium. In the U.S, barite is mined primarily in Nevada and Georgia. Much care must be taken to remove the mined ...
