Jim, Jill, Robert, and Kim each run paper chromatography on an unknown aqueous mixture. Jim gets a red band and a blue band, Jill gets a yellow band and a blue band, Robert gets a green band, and Kim gets a red band and a yellow band.

Please any help I really really need it I would be so grateful I think it might be Robert because there is only one color.

I believe this to be a spectrometry question and from what i can recall, blue or violet is the lowest in energy.. Now from this i can assume that if each aqueous mixture had chemical bonds.. i think it would be safe to assume that the chemical with the most mixtures would require more bonds and more electrons to be bouncing up and down.. since violet or bluish is less energy i would assume it to be the one with least amount of different chemicals.
