Balanced equation

Balance the chemical equation algebraically: SbCl_3 + ReCl_5 ⟶ SbCl_5 + Cl_4Re Add stoichiometric coefficients, c_i, to the reactants and products: c_1 SbCl_3 + c_2 ReCl_5 ⟶ c_3 SbCl_5 + c_4 Cl_4Re Set the number of atoms in the reactants equal to the number of atoms in the products for Cl, Sb and Re: Cl: | 3 c_1 + 5 c_2 = 5 c_3 + 4 c_4 Sb: | c_1 = c_3 Re: | c_2 = 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_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 2 c_3 = 1 c_4 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | SbCl_3 + 2 ReCl_5 ⟶ SbCl_5 + 2 Cl_4Re
