Balanced equation

Balance the chemical equation algebraically: NaOH + H_2O_2 + SnS ⟶ H_2O + Na_2SO_4 + Na_2SnO_3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 NaOH + c_2 H_2O_2 + c_3 SnS ⟶ c_4 H_2O + c_5 Na_2SO_4 + c_6 Na_2SnO_3 Set the number of atoms in the reactants equal to the number of atoms in the products for H, Na, O, S and Sn: H: | c_1 + 2 c_2 = 2 c_4 Na: | c_1 = 2 c_5 + 2 c_6 O: | c_1 + 2 c_2 = c_4 + 4 c_5 + 3 c_6 S: | c_3 = c_5 Sn: | c_3 = c_6 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 = 4 c_2 = 5 c_3 = 1 c_4 = 7 c_5 = 1 c_6 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 4 NaOH + 5 H_2O_2 + SnS ⟶ 7 H_2O + Na_2SO_4 + Na_2SnO_3
