In Zubrick’s chapter "The Theory of Extraction, he shows you mathematically why several smaller extractions are more efficient than one big one. The solubility data for benzoic acid is: 10 g/100 mL ether and 1g/100 mL water. What is the partition coefficient, Kp? If you have 300 mL of an aqueous solution containing 1.80 g of benzoic acid, prove that 3 successive extractions using 40 mL of ether each time is more efficient (92% of benzoic acid extracted) than using just one 120 mL extraction (which captures only 80% of the benzoic acid in the ether layer).

In meteorology, a  cloud  is an aerosol consisting of a visible mass of minute liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body. nephology is the science of  clouds, which is undertaken in the  cloud  physics branch of meteorology.cirrus clouds  usually describe clouds high in the atmosphere that can include wispy clouds, typically with ice crystals. variations include cirrus, cirrocumulus and cirrostratus as defined by the cloud's position in the atmosphere.layered stratus clouds  have both flat tops and bases, and can appear as if they take up the whole sky, stretching from horizon to horizon. other combinations and variations include stratus, stratocumulus, nimbostratus and altostratus.cumulus clouds  often pile up in multiple layers of the atmosphere, representing clouds that develop vertically. cumulus clouds often look like pillars with anvil-type tops or columns of clouds stacked vertically. variations include cumulus, cumulus-congestus, cumulonimbus and altocumulus.

What are the choices?

The correct answer is b) false

Yeah, but what are you trying to ask?
