Input interpretation
calcium hydroxide + citric acid ⟶ water + C2O + Ca3C12H10O14
Balanced equation
Balance the chemical equation algebraically: + ⟶ + C2O + Ca3C12H10O14 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 ⟶ c_3 + c_4 C2O + c_5 Ca3C12H10O14 Set the number of atoms in the reactants equal to the number of atoms in the products for Ca, H, O and C: Ca: | c_1 = 3 c_5 H: | 2 c_1 + 8 c_2 = 2 c_3 + 10 c_5 O: | 2 c_1 + 7 c_2 = c_3 + c_4 + 14 c_5 C: | 6 c_2 = 2 c_4 + 12 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 = 3 c_3 = 4 c_2 - 2 c_4 = 3 c_2 - 6 c_5 = 1 The resulting system of equations is still underdetermined, so an additional coefficient must be set arbitrarily. Set c_2 = 3 and solve for the remaining coefficients: c_1 = 3 c_2 = 3 c_3 = 10 c_4 = 3 c_5 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 3 + 3 ⟶ 10 + 3 C2O + Ca3C12H10O14
