Input interpretation
water + oxygen + gold + potassium cyanide ⟶ potassium hydroxide + potassium dicyanoaurate(I)
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 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, Au, C, K and N: H: | 2 c_1 = c_5 O: | c_1 + 2 c_2 = c_5 Au: | c_3 = c_6 C: | c_4 = 2 c_6 K: | c_4 = c_5 + c_6 N: | c_4 = 2 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_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 2 c_2 = 1 c_3 = 4 c_4 = 8 c_5 = 4 c_6 = 4 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 2 + + 4 + 8 ⟶ 4 + 4
