Input interpretation
hydrogen sulfide + iron(III) hydroxide ⟶ water + Fe2S3
Balanced equation
Balance the chemical equation algebraically: + ⟶ + Fe2S3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 ⟶ c_3 + c_4 Fe2S3 Set the number of atoms in the reactants equal to the number of atoms in the products for H, S, Fe and O: H: | 2 c_1 + 3 c_2 = 2 c_3 S: | c_1 = 3 c_4 Fe: | c_2 = 2 c_4 O: | 3 c_2 = c_3 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 = 3 c_2 = 2 c_3 = 6 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 3 + 2 ⟶ 6 + Fe2S3
