Using Avogadro’s law (n = kV) Case 1: All the hydrogen reacts, ½ the oxygen is unreacted 2 H 2 +2 O 2 2 H 2 O+O 2 Case 2: All the hydrogen and oxygen react 2 H 2 +O 2 2 H 2 O • Unbalanced: H 2 (g) + O 2 (g) H 2 O(l) • Balanced, Detailed: 2 H 2 (g) + 2 O 2 (g) 2 H 2 O(l) + O 2 (g) reactants products Stoichiometric coefficients give the number of molecules or moles of each species involved in the reaction.
