In a paper chromatography analysis, three pigments, a, b, and c, were dissolved in ivent. a is slightly polar, b is highly polar, and c is moderately polar. list in order how these will appear on the surface of the chromatography strip starting from the applied spot at the origin line.

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
