He obtaincd the chromatogram of the individual dyes and the mixture shown below. solvent front G3 Y5 R3 B1 Mix origin line (a) Measure the distance the solvent front moved. solvent front (b) Measure the distance each spot moved. G3 Y5 R3 B1 (c) Calculate the Rf for each component. G3 Y5 R3 B1 (d) Which dye(s) can the student say, with certainty, is/are present in the mixture? (e) Is water with 2% NaCl a good choice for the resolution of the mixture? Briefly explain.

Researchers isolated an unknown substance, X, from rabbit muscle. They determined its structure from the following observations and experiments. (a) Qualitative analysis showed that X was composed entirely of C, H, and O. A weighed sample of X was completely oxidized, and the H2O and CO2 produced were measured. This quantitative analysis revealed that X contained 40.00% C, 6.71% H, and 53.29% O by weight. (b) The molecular mass of X, as determined by mass spectrometry, was 90.00 atomic mass units (u). (c) Infrared spectroscopy showed that X contained one double bond. (d) X dissolved readily in water, and the solution demonstrated optical activity when tested in a polarimeter. (e) The aqueous solution of X is acidic. What is the empirical formula of X?

These metals are catalysts because: They cause the reactions without being affected. They are formed into a honeycomb shape. They are metals. They help produce less harmful gasses.
