Balanced equation

Balance the chemical equation algebraically: H_2S + Sc2(SO4)3 ⟶ H_2SO_4 + Sc_2S_3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2S + c_2 Sc2(SO4)3 ⟶ c_3 H_2SO_4 + c_4 Sc_2S_3 Set the number of atoms in the reactants equal to the number of atoms in the products for H, S, Sc and O: H: | 2 c_1 = 2 c_3 S: | c_1 + 3 c_2 = c_3 + 3 c_4 Sc: | 2 c_2 = 2 c_4 O: | 12 c_2 = 4 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 = 3 c_2 = 1 c_3 = 3 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 3 H_2S + Sc2(SO4)3 ⟶ 3 H_2SO_4 + Sc_2S_3
