This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at inorganic compounds by element . There is no complete list of chemical compounds since by nature the list would be infinite. Chemical Formula Search Help Rules for chemical formulas (Back to search) Enter a sequence of element symbols followed by numbers to specify the amounts of desired elements (e.g., C6H6). Use correct case for element symbols. If correct case is not used, the formula may be ambiguous and the interpretation chosen may not be the desired one. Chemical formula, any of several kinds of expressions of the composition or structure of chemical compounds. The forms commonly encountered are empirical, molecular, structural, and projection formulas. A ___ is a number placed in front of a chemical formula to indicate a given number of molecules or positive and negative ion groups. Coefficient The definite amount of a compound represented by a formula is a called a ___. Simply write the formula in terms of the oxidation numbers for the elements. The sum of the oxidation numbers for a compound must be zero.
