Adistillation column separates 16,000 kg/h of a 70% benzene and 30% toluene. the product recovered from the top contains 95% benzene while the bottom product contains 96% toluene. the stream entering the condenser from the top of the column is 8,000 kg/h. a portion of the product is returned to the column as reflux and the remaining is withdrawn as top product. find the ratio of the amount refluxed to the product taken out.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
