SnCl2AgNO3 ⟶ SnNO3AgCl2
Balanced equation
Balance the chemical equation algebraically: SnCl2AgNO3 ⟶ SnNO3AgCl2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 SnCl2AgNO3 ⟶ c_2 SnNO3AgCl2 Set the number of atoms in the reactants equal to the number of atoms in the products for Sn, Cl, Ag, N and O: Sn: | c_1 = c_2 Cl: | 2 c_1 = 2 c_2 Ag: | c_1 = c_2 N: | c_1 = c_2 O: | 3 c_1 = 3 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: | | SnCl2AgNO3 ⟶ SnNO3AgCl2
