Balanced equation

Balance the chemical equation algebraically: H_2O + AgNO_3 + AsH_3 ⟶ HNO_3 + Ag + As(OH)_3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2O + c_2 AgNO_3 + c_3 AsH_3 ⟶ c_4 HNO_3 + c_5 Ag + c_6 As(OH)_3 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, Ag, N and As: H: | 2 c_1 + 3 c_3 = c_4 + 3 c_6 O: | c_1 + 3 c_2 = 3 c_4 + 3 c_6 Ag: | c_2 = c_5 N: | c_2 = c_4 As: | c_3 = c_6 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_3 = 1 and solve the system of equations for the remaining coefficients: c_1 = 3 c_2 = 6 c_3 = 1 c_4 = 6 c_5 = 6 c_6 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 3 H_2O + 6 AgNO_3 + AsH_3 ⟶ 6 HNO_3 + 6 Ag + As(OH)_3
