Balanced equation

Balance the chemical equation algebraically: N2O5H2O ⟶ HNO_3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 N2O5H2O ⟶ c_2 HNO_3 Set the number of atoms in the reactants equal to the number of atoms in the products for N, O and H: N: | 2 c_1 = c_2 O: | 6 c_1 = 3 c_2 H: | 2 c_1 = c_2 Since the coefficients are relative quantities and underdetermined, choose a coefficient to set arbitrarily. To keep the coefficients small, the arbitrary value is ordinarily one. For instance, set c_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | N2O5H2O ⟶ 2 HNO_3
