Rf values are used mainly for simplicity. These values are generally easier to use to obtain percentages between a couple objects instead of using values that are already established.
Rf values are determined by the polarity of the substance tested. Even though these atoms may have similar electron configuration, it is not identical, and neither are their Rf values.
the rf values would increase
Rf values can be used to identify the type of drugs that had been taken by those who went through drug overdose.
Rf Values determine the solubility of a substance with respect to a certain solvent.
The order of increasing RF values in TLC is Benzil, methanol anthracene and tryphenyl.
The Rf values are very important in the analysis of amino acids in this situation. This is because they provide the information and basic groundwork data that can be used in reviewing the results of any further experiments.
RF- Radio Frequency, which is in the measure of kilo & mega Hz range
Rf value to compare the "unknown" components of colored candy dyes with the "known" components of food coloring dyes.
No. The molecules MAY (and probably are if you are presented with this situation in school/college lab courses) be identical but just the Rf values is not enough information to determine, you must conduct additional tests. Two different molecules can have the same Rf value.Compound A will always have an Rf of X in solvent M. Compound B will always have and Rf of Y in solvent M. But, Rf X can be equivalent to Rf Y without compounds A and B being identical.
expected market return = risk free + beta*(market return - risk free) So by putting in values: 20.4 = rf+ 1.6(15-rf) expected market return = risk free + beta*(market return - risk free) So by putting in values: 20.4 = rf+ 1.6(15-rf) where rf = risk free 20.4 - 24 = rf - 1.6rf -3.6 = -0.6rf rf = 6
RF means radio frequency or relativity low range of frequency microwaves however are into the top range of the spectrum or very hi frequency.
