Below are 2 different compounds that I need help identifying. I have attached the NMR and IR spectra that we gathered. We have a couple ideas of what they could be and made marks on the spectra but would like an expert's help with finalizing them. The second NMR spectra is supposed to have a peak around 12-14 for a carboxylic acid but did not show up on ours and it was confirmed that it should be there. There aren't any base peaks either, we had to go into this blind. Thank you so much!

Write a program that first generates a random integer between 1 and 100, and provide the player with its modulus i e the remainders when divided by 2, 5, or 13.

(20 pts Carbon dating is a method that determines the age of fossils based on samples' Carbon 14 radioactivity. Carbon 14, or radiocarbon, is an isotope of the element carbon that is unstable and weakly radioactive. Plants and animals assimilate carbon 14 from carbon dioxide throughout their lifetimes, therefore the level of C14 when they are alive is quite stable. When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay Noe where Nis the remaining radioactivity as a function of time (or age) t, No is the initial radioactivity, k is the rate of decay, and t is time s known that the ha e of C-14 is 5730 years. In other words, it takes 5730 years for its radioactivity to drop to the half of the original level, or N/N 0.5 Write a program that will calculate a sample's age based on its radioactivity. Brief steps 1) Calculate the rate constant k based on the half life of C14 2) Prompt the user for the sample's radioactivity in percentage (N/NoD 3) Calculate sample' age 4) Display the result nicely 5.
