Balanced equation

Balance the chemical equation algebraically: CH3CH2Cl + NaPb ⟶ NaCl + Pb + (C_2H_5)_4Pb Add stoichiometric coefficients, c_i, to the reactants and products: c_1 CH3CH2Cl + c_2 NaPb ⟶ c_3 NaCl + c_4 Pb + c_5 (C_2H_5)_4Pb Set the number of atoms in the reactants equal to the number of atoms in the products for C, H, Cl, Na and Pb: C: | 2 c_1 = 8 c_5 H: | 5 c_1 = 20 c_5 Cl: | c_1 = c_3 Na: | c_2 = c_3 Pb: | c_2 = c_4 + c_5 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_5 = 1 and solve the system of equations for the remaining coefficients: c_1 = 4 c_2 = 4 c_3 = 4 c_4 = 3 c_5 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 4 CH3CH2Cl + 4 NaPb ⟶ 4 NaCl + 3 Pb + (C_2H_5)_4Pb
