An aqueous glucose stream is to be catalytically hydrogenated to sorbitol in a slurry tank reactor. feeds to the reactor are an aqueous glucose stream with a concentration of 2.6 kg mol/m at a flow rate of 10-3 m/s and a 120 percent of stoichiometric hydrogen gas stream. the reactor is to be operated isothermally at 423 k, where the reaction is observed to follow the kinetics shown here: -rglucose = kchydrogen glucose k423 k = 3.76 x 10-4 (kg mol/m? ) -0.6s-1 the reaction is conducted at 10,000 kpa, the solubility of hydrogen may be assumed to be 5 kg mol/m at this pressure.

heat or electricity in the atmosphere- c.

- decrease the number of plants and animals living in the water.

d.) circle motion requires a force to give it a centripetal acceleration.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
