The surface of a 2.5 mm thick ammonia (A) (NH3) – water (B) (H2O) solution at 298 K is in contact with an organic liquid. At the interface (the surface in contact with the organic liquid and water), the equilibrium concentration of ammonia in water is kept constant at 3% by weight (aqueous solution density at this first point, 992.5 kg/m3). 2.5 mm away, at the other border of the film, the concentration of ammonia in water is 12% by weight (the density of the aqueous solution at this second point is 962.3 kg/m3). The water and organic phase are insoluble in each other. (MA = 17.03 kg/kgmol, MB = 18 kg/kgmol) (Assume the ammonia-water solution is 100 kg.) (a) Calculate the diffusibility of ammonia in water using the Wilke-Chang correlation. (Water viscosity at 298 K, B = 0.8937 x 10-3 Pa. s) (b) Calculate the steady state NA flux.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

Two people each hold the end of a rope and create waves by moving their arms up and down. this wave is best classified as a transverse wave because a) both the rope particles and the wave are moving in the same direction. b) the wave is moving up and down as the particles of the rope move horizontally. c) the wave is moving horizontally as the particles of the rope move up and down. eliminate d) the wave is moving in a parallel direction with the motion of the person's arms.
