well because all colours are made up of different ones except yellow,orange,and permant black and others OK!

Why did different dyes travel up the filter paper at different rates in paper chromatography?
different dyes travel with different speed/rates on filter paper in paper chromatography as they have nothing to do with the filter paper as it is the stationary medium while the rates depends upon the interaction between the solute i.e., dyes and the mobile phase i.e., the solvent.
What is the difference between partition chromatography and adsorption chromatography?
The partition chromatography involves separation between liquids while adsoption chromatography involves solid and liquid separations. Answer: Partition Chromatography is a liquid liquid extraction which involves two solvents while adsorption chromatography is a liquid solid extraction which involves a solid stationary phase & a liquid mobile phase.
How different colors are discovers what colors are in each ink using chromatography?
The different substances present in the ink have different Rf values (Rf value is the ratio of the distance the dissolved material traveled to distance the solvent traveled) the different substances each have a unique or nearly unique Rf value. This occurs because each material's chemical structure has a different solubility in the solvent,used to develop the chromatography plate,. This means that some compounds easily dissolve and are carried by the solvent while others are more attracted to the chromatgraphy plate and don't budge as easily. Hope this helped. sincerely, a chem major
What is the basis of molecular sieve chromatography?
The purification in molecular sieve chromatography is dependent on the size of the molecules. The small molecules will enter into pores of gel while large molecules will be excluded from the pores.
Disadvantages of using paper chromatography?
TLC has following advantages over paper chromatography: greater speed greater sensitivity for many substances than paper Small sample requirement Usually sharper preparation Different kind of reagents can be applied without damaging the plate
What would the result be if while carrying out TLC chromatography you used a solvent of 200 is to 1 ethyl acetate and aqueous ammonia instead of 200 is to 1 ethyl acetate and acetic acid?
chromatography is when two substances separate. iprdufwjiwreusdoi

How can paper chromatography be used to separate pigments based on their chemical and physical properties?
It is an appropriate technique to use because it separates the pigments, so one can see which pigments are present, even if some pigments are normally hidden to the naked eye.
Do atoms slowly separate while heated?
Quite possible, though the temperature at which the atoms separate will vary for different atoms.

Will using a cheat in GTA4 disable achievements permanently?
no just while they are active. I recommend not using while doing missions but have a separate save slot just for running around with cheats on. Hope this helps

Why does red ink travel further than yellow ink in chromatography?
because yellow is a bigger particle, and in chromatography, the bigger molecules/particles fall out first, while the smaller particles continue moving.
Why is it easier to separate a mixture of iron and sulfur than to separate a compound of iron and sulfur?
because a mixture is physically combine while a compound is chemically combine thus make is eaiser for the mixture to separate using the technique magnetic separation.
What are the advantages and limitations of column chromatography over thin layer chromatography?
TLC. The mobile phase is a liquid, the stationary phase is a solid. Useful for seperating and comparing mobility of solids and some liquids dissolved in the mobile phase by their affinities to the solid phase relative to the mobile phase. GLC. The mobile phase ia s gas, the stationary phase is a liquid on a solid support. same concept as TLC. useful for seperating gases by their affinities to the stationary phase...the mobility can then be compared to known compounds for possible identification.
