A researcher wants to calculate the flux of palm oil (PO) in a simulated body fluid (SBF). To perform the experiment, he designed a 30 cm capillary tube. At the very beginning of the tube, he designed a partition with a separator as shown in the figure below. He filled the partition with a stock solution prepared by solving 10 g of PO in a liter of SBF and the capillary tube with pure SBF. Then he removed the separator. The viscosity of the BSF is 3.6x10-3 Pa.s and molecular weight of PO is 850.92.a. Calculate the flux of PO in kg mol/s.m2 at steady state. (Use Polson equation for diffusivity.) (Assume the temperature is maintained at 37oC during whole experiment.)b. Concentration of PO at the half of the tube.

The percent recovery of recrystallized solid was less than 100%. c. A solid that was recrystallized from hexane was filtered and dried without washing with additional hexane while it was on the filter funnel. d. A solid recrystallized from toluene was left on the filter funnel for only a short time before its melting point was measured. e. The melting point capillary tube was packed with too much material.
Pls do fast within 5 minutes and i will give like for sure Solution must be in typed form To plan a liquid–liquid extraction we need to know the solute’s distribution ratio between the two phases. One approach is to carry out the extraction on a solution that contains a known amount of solute. After the extraction, we isolate the organic phase and allow it to evaporate, leaving behind the solute. In one such experiment, 1.235 g of a solute with a molar mass of 117.3 g/mol is dissolved in 10.00 mL of water. After extracting with 5.00 mL of toluene, 0.889 g of the solute is recovered in the organic phase. If we extract 20.00 mL of an aqueous solution that contains the solute using 10.00 mL of toluene, what is the extraction efficiency?

Describe the behavior on distillation of a 98% ethanol solution through an efficient column. Refer to the figure.
TRUE OR FALSE Powders that have low density and high porosity are free flowing. Surface roughness leads to poor flow characteristics. Micromeritics affects the maximum penetration of inhalation aerosols based on particle size. The greater the number of particles per dose, the lower the variability between dosage units. Bulk volume is the volume of spaces. Laser light scattering technique enables the use of surfactants to determine the primary particle size. The bioavailability of poorly soluble drugs influenced by state of subdivision of the drug. Spatulation is the technique of choice when blending small amounts of powders. Bulkiness decreases with increase in particle size Powders require disintegration before the onset of action. The more asymmetric a particle, the greater the surface area per unit volume Packing is the ratio of the void volume to the bulk volume.
