Input interpretation

AgNO_3 (silver nitrate) + ZnCl_2 (zinc chloride) ⟶ Zn(NO3)2 + AgCl (silver chloride)

Balanced equation

Balance the chemical equation algebraically: AgNO_3 + ZnCl_2 ⟶ Zn(NO3)2 + AgCl Add stoichiometric coefficients, c_i, to the reactants and products: c_1 AgNO_3 + c_2 ZnCl_2 ⟶ c_3 Zn(NO3)2 + c_4 AgCl Set the number of atoms in the reactants equal to the number of atoms in the products for Ag, N, O, Cl and Zn: Ag: | c_1 = c_4 N: | c_1 = 2 c_3 O: | 3 c_1 = 6 c_3 Cl: | 2 c_2 = c_4 Zn: | 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_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 2 c_2 = 1 c_3 = 1 c_4 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 2 AgNO_3 + ZnCl_2 ⟶ Zn(NO3)2 + 2 AgCl
