help needed with this problem set Refer to the HPLC chromatograms below for a 5-component mixture of organic acids for the following questions. The specific HPLC parameters for chromatogram A (top) are described in the figure title and the insert. You only need the lecture notes and/or your personal experience to answer those questions. Mobile phase: 30 % MeCN, 70 % TFA, 0.1 M (pH 2.0) low rate: 1.0 mL/min 2Benzok Acid Maleic Aci 1. (a) Which component has the...
5. Using the GC mentioned in question 4 and the values listed on the chromatogram for the height and width (at half height) of each peak, calculate the percent composition for each product (A, B and C). Be sure to show your work. (8 points) 6. The products corresponding to each peak on the GC are the ortho, meta, and para isomers of the nitrated product shown in the scheme for reaction 1. These isomers were isolated, and a proton...
NEED HELP WITH B) C) D) E) F) and G) that apply to the spectra below. OTHER ANSWERS ARE THERE TO SUPPLEMENT Thank you! 5. Using the GC mentioned in question 4 and the values listed on the chromatogram for the height and width (at half height) of each peak, calculate the percent composition for each product (A, B and C). Be sure to show your work. Area of peak A = 125 x 8 = 1000mm2 Area of peak...
Problem 2(10 points): The natural composition of uranium and the half-life of the isotopes are given below in the table. Isotope |At90 Half-life (vrs) U-234 0.005% 2.455 x 10 0.711% 17.038 x 108 U-23899.284% 4.468 x 109 U-235 Assume earth was formed 4.54 x 109 years ago. The ratio of U-235 to U-238 has been steadily decreasing since than. (a) Calculate the enrichment of U-235 (in atom percent) at the time of formation of the earth (t=0) (b) Calculate the...
Problem 7 (20 points): Each graph below shows the relative intensity versus 0 for a double slit experiment. The horizontal scale is the same for all graphs. The only possible differences among the cases are the values of the slit width (a) and distance between the centers of the slits (d). Case For each of the three cases, calculate the ratio- a) 0.5 b) Rank the cases according to distance between the centers Case 2 of the slits (d), from...
