Input interpretation

Balanced equation

Balance the chemical equation algebraically: H_2SO_4 + NH_4OH ⟶ H_2O + (NH_4)_2SO_4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2SO_4 + c_2 NH_4OH ⟶ c_3 H_2O + c_4 (NH_4)_2SO_4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, S and N: H: | 2 c_1 + 5 c_2 = 2 c_3 + 8 c_4 O: | 4 c_1 + c_2 = c_3 + 4 c_4 S: | c_1 = c_4 N: | c_2 = 2 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 = 2 c_3 = 2 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | H_2SO_4 + 2 NH_4OH ⟶ 2 H_2O + (NH_4)_2SO_4
