Complete the following paragraph.

The stationary phase in TLC is polarnonpolaracidic . Therefore, the more polarless polarmore acidic component of the mixture will travel a greater distance up the plate, resulting in a –––––– value for the component.

When separating a mixture containing benzoic acid, 2,4-dinitrobenzoic acid, and 2,4,6-trinitrobenzoic acid, the (benzoic acid, 2,4-dinitrobenzoic acid, 2,4,6-trinitrobenzoic acid) spot would be expected to travel the greatest distance up the plate as it is the (most acidic, most polar, least polar) component. The (2,4,6-trinitrobenzoic acid, benzoic acid, 2,4-dinitrobenzoic acid) would travel the least distance as it is the (least polar, least acidic, most polar) component.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
