Input interpretation
potassium hydroxide + bromine + chromium nitrate ⟶ water + potassium dichromate + potassium nitrate + potassium bromide
Balanced equation
Balance the chemical equation algebraically: + + ⟶ + + + Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 + c_3 ⟶ c_4 + c_5 + c_6 + c_7 Set the number of atoms in the reactants equal to the number of atoms in the products for H, K, O, Br, Cr and N: H: | c_1 = 2 c_4 K: | c_1 = 2 c_5 + c_6 + c_7 O: | c_1 + 9 c_3 = c_4 + 7 c_5 + 3 c_6 Br: | 2 c_2 = c_7 Cr: | c_3 = 2 c_5 N: | 3 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_5 = 1 and solve the system of equations for the remaining coefficients: c_1 = 14 c_2 = 3 c_3 = 2 c_4 = 7 c_5 = 1 c_6 = 6 c_7 = 6 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 14 + 3 + 2 ⟶ 7 + + 6 + 6
