Balanced equation

Balance the chemical equation algebraically: HCl + NaBrO_3 + SbCl_3 ⟶ H_2O + NaBr + SbCl_5 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 HCl + c_2 NaBrO_3 + c_3 SbCl_3 ⟶ c_4 H_2O + c_5 NaBr + c_6 SbCl_5 Set the number of atoms in the reactants equal to the number of atoms in the products for Cl, H, Br, Na, O and Sb: Cl: | c_1 + 3 c_3 = 5 c_6 H: | c_1 = 2 c_4 Br: | c_2 = c_5 Na: | c_2 = c_5 O: | 3 c_2 = c_4 Sb: | 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_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 6 c_2 = 1 c_3 = 3 c_4 = 3 c_5 = 1 c_6 = 3 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 6 HCl + NaBrO_3 + 3 SbCl_3 ⟶ 3 H_2O + NaBr + 3 SbCl_5
