Why should the water be below the pencil line in chromatography?
because when we usually test for a liquid or anything soluble we put a drop of it on the pencil line, then when we put the chromatography paper or filter paper in water the water will get on the paper and start moving upwards here when the water will approach the liquid or solvent or die and then they will move with water throughout the filter or chromatography paper.
Pencil living ya nonliving?
No, a pencil is not alive. We know we are alive because we move, grow, and change. A pencil does not move, grow or change unless we move it or change it (for example: by sharpening the pencil).

Difference Rf values for monosaccarides and disaccharides?
Monosaccarides contain fewer polar covalent glycosidic bonds than polysaccharides and therefore move further up during thin layer chromatography and column chromatography.
How does gravity affect your pencil if you let go of it in mid air?
Your pencil and the Earth both have mass. For that reason, there are always a pairof gravitational forces trying to pull the pencil and Earth together toward each other.Most of the time, you're holding onto the pencil and not letting them move towardeach other. But when you let go of the pencil, then both the pencil and the Earthare free to move. Then the Earth falls toward the pencil, and the pencil falls towardthe Earth. The motion stops when the floor and the pencil meet.
