Chemical Equations: Their Job Depict the kind of reactants and products and their relative amounts in a reaction. 4 Al (s) + 3 O2 (g) → 2 Al2O3 (s) The numbers in the front are called stoichiometric coefficients. The letters (s), (g), and (l) are the physical states of com...
In reactions under normal laboratory conditions, matter is neither created nor destroyed, and elements are not transformed into other elements. Therefore, equations depicting reactions must be balanced; that is, the same number ofatomsof each kind must appear on opposite sides of the equation. The...
The author has attempted to remedy this very common weakness, and in addition to a concise explanation of chemical notation, including difficult cases of oxidation and reduction and ionic reactions, has provided a list of more than four hundred classified and indexed chemical equations. The book ...
