AgNO3NaCl ⟶ AgClNaNO3

Balance the chemical equation algebraically: AgNO3NaCl ⟶ AgClNaNO3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 AgNO3NaCl ⟶ c_2 AgClNaNO3 Set the number of atoms in the reactants equal to the number of atoms in the products for Ag, N, O, Na and Cl: Ag: | c_1 = c_2 N: | c_1 = c_2 O: | 3 c_1 = 3 c_2 Na: | c_1 = c_2 Cl: | c_1 = c_2 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 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | AgNO3NaCl ⟶ AgClNaNO3
