The net flow of salt in water delta can generate energy via osmosis. The rate constant can only be determined experimentally and does not depend on concentration. Calculate the mole fraction of nitric acid (HNO_3) of a 17.5% (by mass) aqueous solution of nitric add. A) 0.0607 B) 0.0572 C) 0.278 D) 3.37 E) 1.75 Calculate the vapor pressure of a solution made by dissolving 109 grams of glucose (mass = 180.2 g/mol) in 920.0 g of water at 25 degree C. The vapor pressure of pure water at 25 degree C 23.76 mm Hg. A) 0.278 mm Hg B) 0.605 mm Hg C) 0.285 mm Hg D) 23.5 mm Hg E) 23.8 mm Hg Name the three type of interactions in a bulk solution. Polar molecules have net dipoles. Please give three examples of molecules with net and draw the overall dipole moment superimposed on the molecule. What is the average rate for the following chemical equations? a) H_2 + I_2 rightarrow 2HI b) C_6 H_5 COCH_3 rightarrow C_6 H_5 CO^+ + CH_3 c) H_2 O_2 rightarrow H_2 + O_2
