Balanced equation

Balance the chemical equation algebraically: H_2 + Al + C_2H_2 ⟶ (C2H5)3Al Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2 + c_2 Al + c_3 C_2H_2 ⟶ c_4 (C2H5)3Al Set the number of atoms in the reactants equal to the number of atoms in the products for H, Al and C: H: | 2 c_1 + 2 c_3 = 15 c_4 Al: | c_2 = c_4 C: | 2 c_3 = 6 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_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 9/2 c_2 = 1 c_3 = 3 c_4 = 1 Multiply by the least common denominator, 2, to eliminate fractional coefficients: c_1 = 9 c_2 = 2 c_3 = 6 c_4 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 9 H_2 + 2 Al + 6 C_2H_2 ⟶ 2 (C2H5)3Al
