Balanced equation

Balance the chemical equation algebraically: Cu(OH)_2 + CH_3COONa ⟶ NaOH + (CH3COO)2Cu Add stoichiometric coefficients, c_i, to the reactants and products: c_1 Cu(OH)_2 + c_2 CH_3COONa ⟶ c_3 NaOH + c_4 (CH3COO)2Cu Set the number of atoms in the reactants equal to the number of atoms in the products for Cu, H, O, C and Na: Cu: | c_1 = c_4 H: | 2 c_1 + 3 c_2 = c_3 + 6 c_4 O: | 2 c_1 + 2 c_2 = c_3 + 4 c_4 C: | 2 c_2 = 4 c_4 Na: | c_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 = 2 c_3 = 2 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | Cu(OH)_2 + 2 CH_3COONa ⟶ 2 NaOH + (CH3COO)2Cu
