Apaper chromatography experiment was conducted on a mixture of amino acids including aspartic acid (asp), glutamic acid (glu), histidine (his), leucine (leu), phenylalanine (phe) and proline (pro). the following rf values were determined: asp (0.245), glutamic (0.275), his (0.295), leu (0.745), phe (0.685) and pro (0.445). in the experiment, a colored spot for unknown amino acid "x" was found centered at a distance 61 mm from the start line when the solvent line had travelled 82 mm. (1) show the calculation for the rf value for amino acid "x" and (2) identity amino acid "x". - click here to enter answer - which of the following is the formula of unknown #1 which gives the following sem spectrum. explain your answer. bs2o3 so3br ba(hso4)2
