Suppose you are performing an extraction procedure with a carboxylic acid, like a benzoic or toluic acid. Which layer should contain the carboxylic acid in a two-layer mixture of water and an organic solvent, like diethyl ether?

diethyl ether

Explanation:

Benzoic acid and toluic acid are more soluble in organic solvents than in water. Even though many carboxylic acids with a short alkyl chain are soluble in water due to hydrogen bonding, aromatic carboxylic acids are only slightly soluble in water.

However, when converted to benzoates, these species are now more soluble in water than in organic solvents.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
