For all of the Mass spectroscopy below, please find the Ion peak, M+1, M+2 peak, and show the different reactions ( For M+1 and M+2) that took place in each picture such as alpha cleavage, hydration, and mc Lafferty? If it is possible to show each reaction in the MS uploaded the picture, not the separate reaction on the paper. Thanks! The name of the compouds written below of them

Would the exponents, m and n, in your rate expression be larger than, smaller than, or unchanged from the correct values as a result of each of the following mistakes?  Indicate clearly your reasoning. Experiment 3: 20.0mL of 0.10M KI, 5.0mL of distilled water, 5.0mL H2O2 rate = k[H2O2]m[I-]n a) A leak occurred around stopper A in the mouth of the Erlenmeyer flask during experiment 3.

3. Using the data at right: a. Calculate the absorbance of each sample. You will need to express the %T values as decimals before calculating the logarithms. (e.g., for T = 25%, A = -log 0.25 = 0.602) b. Use the graph paper on the back of this page (or a spreadsheet) to plot absorbance vs. concentration. Make a proper graph, with labeled axes, uniform scales, etc. Use a ruler to draw the best-fit line.. C. Use the graph to find the concentration of the un- known sample. (Draw dotted lines on the graph showing how you found your answer.) CONCENTRATION PERCENT (ppm) TRANSMISSION 0 100.0 100 74.1 200 54.9 300 40.7 400 30.1 500 22.3 unknown 31.6 ABSORBANCE

the spectra is of a drug either cannabinoid, opiate, MDMA etc, please explain the spectra and what drug could it be

Please answer all and post below the answer the source from where you got the answer thank you!

can you help me put the graph together

Show a sample calculation of how you converted your initial (t = 0) absorbance reading into a concentration. Copy and paste your three graphs below.

Determine the standard concentration of A through E and then the absorbance. I just need clarification on if I add together the two ml values given.

Project 2: Food Dye Spectroscopy   Which scale is most useful for reporting data from the spectrometer? Why?

1. Determine the concentration of each component (C2) in the final mixture for each run (refer to Table 4-1) for the total volume (V2) of the mixture, and the initial concentration (C1) and volume (V1) of each component). C1V1 = C2V2 2. Calculate for the reaction rate per run using the concentration of iodine and time elapsed. reaction rate = [I2] in the final mixture/time elapsed 3. Determine the reaction order with respect to l2. Also determine the reaction order with respect to C3H6O and the reaction order with respect to HCI. Round off your answers to the nearest whole number. 4. Calculate for the rate constant for each run using the reaction orders obtained (use rounded off values of reaction orders). 5. Take the average of the rate constants. 6. Determine the rate law of the reaction.

Drag the appropriate labels to their respective targets. • View Available Hint(s) MgCl MgCl2 CaCl CaCl2 3 G1 CaCo, + G1 HCI H,O + G1 CO. → G1 G2 + G1 G1 Mg(OH), + G1 HCI G1 H,O G1 G2 + 2.

7. Given the pK, information for different acids below, place the following acids in order of increasing acid strength (from weakest to strongest). Anilinium ion, CSH6N*, pKa = 4.60 Benzilic acid, pka = 3.09 %3D Chloroacetic acid, pKa = 2.98 %3D Dibromophenol, pka = 8.06 %3D a) Anilinium ion → Benzilic acid → Chloroacetic acid → Chloroacetic acid b) Dibromophenol → Chloroacetic acid → Benzilic acid → Anilinium ion c) Chloroacetic acid → Benzilic acid → Anilinium ion → Dibromophenol d) Dibromophenol → Anilinium ion → Benzilic acid → Chloroacetic acid e) Chloroacetic acid → Anilinium ion → Dibromophenol→ Benzilic acid f) none of the above

▪ True or False: In an untargeted analysis by GC-MS, we extract all acidic drugs and all basic drugs using SPE with hydrophobic resin. A)True B)False ▪ In a comprehensive drug screen by GCMS, we set the detector to what mode and why? ▪ A) Full scan; we don't know what analyted are in the sample, so we don't know what m/z to focus the detector's time on. ▪ B) SIM; We have a good id
