Input interpretation
oxygen + Fe2S3 ⟶ sulfur dioxide + iron(III) oxide
Balanced equation
Balance the chemical equation algebraically: + Fe2S3 ⟶ + Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 Fe2S3 ⟶ c_3 + c_4 Set the number of atoms in the reactants equal to the number of atoms in the products for O, Fe and S: O: | 2 c_1 = 2 c_3 + 3 c_4 Fe: | 2 c_2 = 2 c_4 S: | 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_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 9/2 c_2 = 1 c_3 = 3 c_4 = 1 Multiply by the least common denominator, 2, to eliminate fractional coefficients: c_1 = 9 c_2 = 2 c_3 = 6 c_4 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 9 + 2 Fe2S3 ⟶ 6 + 2
