Input interpretation

NH_3 (ammonia) + Hg_2Cl_2 (mercury(I) chloride) ⟶ Hg (mercury) + NH_4Cl (ammonium chloride) + HgNH_2Cl (ammoniated mercuric chloride)
NH_3 (ammonia) + Hg_2Cl_2 (mercury(I) chloride) ⟶ Hg (mercury) + NH_4Cl (ammonium chloride) + HgNH_2Cl (ammoniated mercuric chloride)

Balanced equation

Balance the chemical equation algebraically: NH_3 + Hg_2Cl_2 ⟶ Hg + NH_4Cl + HgNH_2Cl Add stoichiometric coefficients, c_i, to the reactants and products: c_1 NH_3 + c_2 Hg_2Cl_2 ⟶ c_3 Hg + c_4 NH_4Cl + c_5 HgNH_2Cl Set the number of atoms in the reactants equal to the number of atoms in the products for H, N, Cl and Hg: H: | 3 c_1 = 4 c_4 + 2 c_5 N: | c_1 = c_4 + c_5 Cl: | 2 c_2 = c_4 + c_5 Hg: | 2 c_2 = c_3 + c_5 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 = 1 c_5 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 2 NH_3 + Hg_2Cl_2 ⟶ Hg + NH_4Cl + HgNH_2Cl
