Answer:
True
Explanation:
Yes.
The distance that the molecules move depends on their solubility in the solvent and the size of the molecules. Heavy molecules will travel slower and therefore travel a shorter distance in the time the chromatography is run.
We know from such things as felt tip pens that colourings can be soluble in different solvents. Water soluble felt pens have colours that are - well - water soluble. Permanent felt pens have colours that are insoluble in water but that are soluble in another solvent. This could well be alcohol.
The water soluble colours may also be soluble in alcohol. The solubility in alcohol will be different from the solubility in alcohol, and so the Rf value ( the distance travelled) will also be different.
Because of the complicated shapes of the colours, the colours may not have the same order in the Rf values in the different solvents.
Since we already have the balanced equation, we know that the ratio between 
is 
respectively.
So then we can set up a proportion to find the number of moles produced when 2.90 moles of Na react completely:
Then we cross multiply and solve for x:
Therefore, we know that when 2.90 moles of Na react completely, there are 1.45 moles of 
that are produced.
The product would be 2NaCI. Hope this helps xx
I believe it is Sodium. I could be wrong though.
The formula for phosphorus is P4
