Input interpretation
aluminum nitrate ⟶ oxygen + nitrogen dioxide + aluminum 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 Al, N and O: Al: | c_1 = 2 c_4 N: | 3 c_1 = c_3 O: | 9 c_1 = 2 c_2 + 2 c_3 + 3 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_4 = 1 and solve the system of equations for the remaining coefficients: c_1 = 2 c_2 = 3/2 c_3 = 6 c_4 = 1 Multiply by the least common denominator, 2, to eliminate fractional coefficients: c_1 = 4 c_2 = 3 c_3 = 12 c_4 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 4 ⟶ 3 + 12 + 2
