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, explore iconic reactions and predict products.

Reaction Stoichiometry

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.

Find the required amount of reactants:

Determine the theoretical yield:
