Balanced equation

Balance the chemical equation algebraically: H_2SO_4 + Ca(CH3COO)2 ⟶ CH_3CO_2H + CaSO_4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2SO_4 + c_2 Ca(CH3COO)2 ⟶ c_3 CH_3CO_2H + c_4 CaSO_4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, S, Ca and C: H: | 2 c_1 + 6 c_2 = 4 c_3 O: | 4 c_1 + 4 c_2 = 2 c_3 + 4 c_4 S: | c_1 = c_4 Ca: | c_2 = c_4 C: | 4 c_2 = 2 c_3 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 = 1 c_3 = 2 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | H_2SO_4 + Ca(CH3COO)2 ⟶ 2 CH_3CO_2H + CaSO_4
