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.
Use Wolfram|Alpha to find the right coefficients to balance a chemical reaction.
Build expressions necessary for modeling chemical equilibria.
When you specify the amount for one or more reactants or products, Wolfram|Alpha can compute reaction properties such as theoretical yield, percent yield and limiting reactant.
