Input interpretation
hydrogen chloride + hydrogen sulfide + potassium dichromate ⟶ water + mixed sulfur + potassium chloride + chromic chloride
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 Cl, H, S, Cr, K and O: Cl: | c_1 = c_6 + 3 c_7 H: | c_1 + 2 c_2 = 2 c_4 S: | c_2 = c_5 Cr: | 2 c_3 = c_7 K: | 2 c_3 = c_6 O: | 7 c_3 = c_4 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_1 = 8 c_2 = 3 c_3 = 1 c_4 = 7 c_5 = 3 c_6 = 2 c_7 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 8 + 3 + ⟶ 7 + 3 + 2 + 2
