Why must the level ofthe solvent not reach the pencil line where the spots are?
if it wouldn't be above the level of solvent the spots will run off
What would happen if you submerge the chromatography paper above the pencil line?
Try and see: if it wouldn't be above the level of solvent, the spots will run off.
Why must the level of the solvent not reach the pencil line where the spots are?
because the colours would mix together, making the results unreliable
Why is the mixture placed above the level of the solvent in chromatography?
If not, the mixture would just soak out into the liquid in the tank.
Why is it important to stop the chromatograph before the solvent reaches the top of the paper?

Why is it important that the sample spots are not below the solvent level when the filter paper is first placed in the developing chamber?
By placing the spot above the level of the solvent in the beaker, you slow the flow of solvent which results in improved separation of the components in the spot. If you placed it below the level of the solvent in the beaker, the solvent would just flow at a much faster rate and instead of separating the components in the spot, they would simply be washed away.
Does pencil fade on paper?
yes pencil fades on paper overtime especially pencil drawings this is due to the friction caused when paper rubs off against each other even when flipping pages and with moisture one day you will have a dark line drawn of pencil then later the line becomes lighter and lighter until you can easily erase them. On a science level i think its because the paper molecules are breaking down constantly
