Input interpretation
sodium nitrate + sodium azide ⟶ nitrogen + sodium oxide
Balanced equation
Balance the chemical equation algebraically: + ⟶ + Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 ⟶ c_3 + c_4 Set the number of atoms in the reactants equal to the number of atoms in the products for N, Na and O: N: | c_1 + 3 c_2 = 2 c_3 Na: | c_1 + c_2 = 2 c_4 O: | 3 c_1 = c_4 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 = 5 c_3 = 8 c_4 = 3 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | + 5 ⟶ 8 + 3
