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.
What would happen if the Spot of origin is lowered into the solvent in chromatography?
If the original spots were below the level of developing solvent then the components of the spotted sample would dissolve into the solvent and no spots would be seen upon analysis because all of the sample is dissolved in the developing solvent. hope this helps. good luck in o. chem!
What is The appearance of chromatograms in paper chromatography?
The chromatogram in paper chromatography is just the paper itself. You can look at the paper and see the dots that have risen due to the solvent. The appearance is just simply a piece of paper with dots that have risen from the baseline to a certain spot on the paper. see related link below for more info

Why is it important that the level of the elution solvent not drop below the top of the absorbent?
Do not allow the solvent to drain below the absorbent because this will cause cracks.

What is the name for the part of a letter that extends past the baseline?
In typography, any part of a letter that passes below the baseline is called a "descender". Letters with descenders include lowercase g, j, p, q, and y.
How do you dissolve polymer?
Each polymer has a specific solvent; see the link below.
What is a descender in cursive handwriting?
A descender in cursive handwriting refers to the part of a letter that goes below the baseline of the writing line. Letters such as "g", "y", and "q" typically have descenders in cursive handwriting. Descenders add variation to the letters and help with the overall flow and aesthetics of the writing.
What is a shoe tree?
According to Wikipedia (refer to the link, below), "A shoe tree is a device approximating the shape of a foot that is placed inside a shoe to preserve its shape, stop it from developing creases and thereby extend the life of the shoe."
Why are lanthandies placed below the periodic table?
Lanthanides and actinides are placed below the periodic table because of their unique physical and chemical properties.
