Balanced equation

Balance the chemical equation algebraically: NaOH + Ag_2O + Cr(OH)3 ⟶ H_2O + Ag + Na_2CrO_4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 NaOH + c_2 Ag_2O + c_3 Cr(OH)3 ⟶ c_4 H_2O + c_5 Ag + c_6 Na_2CrO_4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, Na, O, Ag and Cr: H: | c_1 + 3 c_3 = 2 c_4 Na: | c_1 = 2 c_6 O: | c_1 + c_2 + 3 c_3 = c_4 + 4 c_6 Ag: | 2 c_2 = c_5 Cr: | 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 = 2 c_2 = 3/2 c_3 = 1 c_4 = 5/2 c_5 = 3 c_6 = 1 Multiply by the least common denominator, 2, to eliminate fractional coefficients: c_1 = 4 c_2 = 3 c_3 = 2 c_4 = 5 c_5 = 6 c_6 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 4 NaOH + 3 Ag_2O + 2 Cr(OH)3 ⟶ 5 H_2O + 6 Ag + 2 Na_2CrO_4
