Iron in the form FeCl2 can be determined by titration with potassium dichromate: 16) 6FeCl2(aq) + K2CriO7(aq) + 14HCl(aq) - 6FeC13(aq) + 2CrC13(aq) + 2KCl(aq) + 7H2O(l) An iron sample of mass 0.800 g required 18.80 mL of 0.0120 M K2CQO7(aq) to reach the end point. How n1c1ny moles of FeCl2 were in the sample?

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

increased stability in the completion of fluorine's outer shell.
