Balanced equation

Balance the chemical equation algebraically: KOH + NH_4NO_3 ⟶ KNO_3 + NH_4OH Add stoichiometric coefficients, c_i, to the reactants and products: c_1 KOH + c_2 NH_4NO_3 ⟶ c_3 KNO_3 + c_4 NH_4OH Set the number of atoms in the reactants equal to the number of atoms in the products for H, K, O and N: H: | c_1 + 4 c_2 = 5 c_4 K: | c_1 = c_3 O: | c_1 + 3 c_2 = 3 c_3 + c_4 N: | 2 c_2 = c_3 + c_4 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 c_3 = 1 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | KOH + NH_4NO_3 ⟶ KNO_3 + NH_4OH
