Input interpretation
oxygen + FeAsS ⟶ sulfur dioxide + iron(III) oxide + As4O6
Balanced equation
Balance the chemical equation algebraically: + FeAsS ⟶ + + As4O6 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 FeAsS ⟶ c_3 + c_4 + c_5 As4O6 Set the number of atoms in the reactants equal to the number of atoms in the products for O, Fe, As and S: O: | 2 c_1 = 2 c_3 + 3 c_4 + 6 c_5 Fe: | c_2 = 2 c_4 As: | c_2 = 4 c_5 S: | 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_5 = 1 and solve the system of equations for the remaining coefficients: c_1 = 10 c_2 = 4 c_3 = 4 c_4 = 2 c_5 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 10 + 4 FeAsS ⟶ 4 + 2 + As4O6
