Input interpretation
iron(III) chloride + sodium iodide ⟶ sodium chloride + FeI3
Balanced equation
Balance the chemical equation algebraically: + ⟶ + FeI3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 ⟶ c_3 + c_4 FeI3 Set the number of atoms in the reactants equal to the number of atoms in the products for Cl, Fe, I and Na: Cl: | 3 c_1 = c_3 Fe: | c_1 = c_4 I: | c_2 = 3 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 = 3 c_3 = 3 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | + 3 ⟶ 3 + FeI3
