If the solvent front moves 8 cm and a component in a sample being analysed moves 3.2 cm from the baseline what is the Rf value for this component?

3.2/8 = 0.4......do check it....

Difference between spectrophotometry and differential spectrophotometry?
Differential spectrophotometry is a spectrophotometric analytical technique in which a solution of the sample's major component is placed in the reference cell and the recorded spectrum represents the difference between the sample cell and the reference cell...basically it uses major component of system as reference and NOT solvent ..for example if a enzyme ligand system is to be assayed ..enzyme + solvent is reference and enzyme + ligand + solvent is test sample..its for quantitative detection.
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!
How do you naturally treat well water?
You may not need to treat it at all. First step is to take a sample to get analysed at a lab and find out how pure it is.
What are the advantages and disadvantages of solvent extraction?
The advantages are: - Goldfish requires less solvent than Soxhlet (solvent in Soxhlet has to reach the siphon level). - Goldfish is quicker because the sample is constantly in contact with the solvent.

What is Rf value?
It is the distance travelled by the sample or analyte divided by distance travelled by the solvent front in chromatography.

You call a well or filtration company . First get a sample analysed at a lab.
Explain why the sample to be seen through a microscope cant be thick?
the light from the lamp below the table would not get through the sample, meaning it could not be seen or analysed.
