Input interpretation
potassium hydroxide + silver nitrate + diazane ⟶ water + nitrogen + potassium nitrate + silver
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 + c_5 + c_6 + c_7 Set the number of atoms in the reactants equal to the number of atoms in the products for H, K, O, Ag and N: H: | c_1 + 4 c_3 = 2 c_4 K: | c_1 = c_6 O: | c_1 + 3 c_2 = c_4 + 3 c_6 Ag: | c_2 = c_7 N: | c_2 + 2 c_3 = 2 c_5 + c_6 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_3 = 1 and solve the system of equations for the remaining coefficients: c_2 = (5 c_1)/6 + 2/3 c_3 = 1 c_4 = c_1/2 + 2 c_5 = 4/3 - c_1/12 c_6 = c_1 c_7 = (5 c_1)/6 + 2/3 The resulting system of equations is still underdetermined, so an additional coefficient must be set arbitrarily. Set c_1 = 4 and solve for the remaining coefficients: c_1 = 4 c_2 = 4 c_3 = 1 c_4 = 4 c_5 = 1 c_6 = 4 c_7 = 4 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 4 + 4 + ⟶ 4 + + 4 + 4
