Input interpretation
HClO3 + selenious acid ⟶ water + chlorine + selenic acid
Balanced equation
Balance the chemical equation algebraically: HClO3 + ⟶ + + Add stoichiometric coefficients, c_i, to the reactants and products: c_1 HClO3 + c_2 ⟶ c_3 + c_4 + c_5 Set the number of atoms in the reactants equal to the number of atoms in the products for H, Cl, O and Se: H: | c_1 + 2 c_2 = 2 c_3 + 2 c_5 Cl: | c_1 = 2 c_4 O: | 3 c_1 + 3 c_2 = c_3 + 4 c_5 Se: | c_2 = 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_3 = 1 and solve the system of equations for the remaining coefficients: c_1 = 2 c_2 = 5 c_3 = 1 c_4 = 1 c_5 = 5 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 2 HClO3 + 5 ⟶ + + 5
