Input interpretation
Cr(OH)3 ⟶ water + chromium(III) oxide
Balanced equation
Balance the chemical equation algebraically: Cr(OH)3 ⟶ + Add stoichiometric coefficients, c_i, to the reactants and products: c_1 Cr(OH)3 ⟶ c_2 + c_3 Set the number of atoms in the reactants equal to the number of atoms in the products for Cr, O and H: Cr: | c_1 = 2 c_3 O: | 3 c_1 = c_2 + 3 c_3 H: | 3 c_1 = 2 c_2 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 c_3 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 2 Cr(OH)3 ⟶ 3 +
