Input interpretation
phosphoric acid + aluminum tribromide + CaCr2O7 ⟶ water + bromine + tricalcium diphosphate + aluminum phosphate + chromium(III) phosphate
Balanced equation
Balance the chemical equation algebraically: + + CaCr2O7 ⟶ + + + + Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 + c_3 CaCr2O7 ⟶ c_4 + c_5 + c_6 + c_7 + c_8 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, P, Al, Br, Ca and Cr: H: | 3 c_1 = 2 c_4 O: | 4 c_1 + 7 c_3 = c_4 + 8 c_6 + 4 c_7 + 4 c_8 P: | c_1 = 2 c_6 + c_7 + c_8 Al: | c_2 = c_7 Br: | 3 c_2 = 2 c_5 Ca: | c_3 = 3 c_6 Cr: | 2 c_3 = c_8 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_6 = 1 and solve the system of equations for the remaining coefficients: c_1 = 14 c_2 = 6 c_3 = 3 c_4 = 21 c_5 = 9 c_6 = 1 c_7 = 6 c_8 = 6 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 14 + 6 + 3 CaCr2O7 ⟶ 21 + 9 + + 6 + 6
