Chemical Reactions

Chemical reactions, the transformation from one molecular structure to another, are ubiquitous in the world around us. Everything from internal combustion engines and complex manufacturing plants to geological processes and life itself depend on chemical reactions. Use Wolfram|Alpha to balance chemical equations, determine reaction stoichiometry and predict products.
