Recommended Problems for Chapters 14, round 2 Problems from Oxtoby: Ch. 14: 13-16, 59, 60, 71-75, 77, 93 Oxtoby is much more calculation-focused than we are; these are intended to help you understand the various aspects of the material and not generally representative of exam questions. Questions similar to some of the more conceptual questions could be exam-like. Additional Problems: Which salt is the most soluble in water? A. Al(PO 4 ) K sp = 10 -20 B. Ba 3 (PO 4 ) 2 K sp = 10 -30 C. Ca 3 (PO 4 ) 2 K sp = 10 -25 D. Cr(PO 4 ) K sp = 10 -24 Calculate how much Cr(PO 4 ) (K sp = 10 -23 ) will dissolve in a 1 L solution that already contains 1 mol of Na 3 (PO 4 ) (K sp ~ 16). Which of the following correctly indicates the relative S and H for dissolving FeCl 3 vs. FeCl 3 *3H 2 O into water? A. S FeCl 3 > S FeCl 3 *3H 2 O and H FeCl 3 > H FeCl 3 *3H 2 O B. S FeCl 3 < S FeCl 3 *3H 2 O and H FeCl 3 > H FeCl 3 *3H 2

Unformatted text preview: O C. ∆ S FeCl 3 > ∆ S FeCl 3 *3H 2 O and ∆ H FeCl 3 < ∆ H FeCl 3 *3H 2 O D. ∆ S FeCl 3 < ∆ S FeCl 3 *3H 2 O and ∆ H FeCl 3 < ∆ H FeCl 3 *3H 2 O For a non-ionic solid, what determines the sign of ∆ H when the solid dissolves in water? You experimentally determine that, at equilibrium, the reaction of hydrogen and fluorine to make hydrofluoric acid has P H2 = 10-30 atm, P F2 = 10-10 atm, and P HF = 1 atm. If another system starts with P H2 = 100 atm, P F2 = 10-18 atm, and P HF = 10-18 atm , will the pressure of HF increase, decrease, or remain unchanged? Justify your answer by determining the sign of ∆ G for this system. A particularly liquid can exist in both cis and trans isomers. Write a valid thermodynamic equilibrium constant for this liquid. 1...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
