Mass spectrometry correct answer: Technique that sorts ions based on their mass to charge ratio Electron ionization correct answer: -Also known as hard ionization -Very energetic, produces fragments ("daughter ions") Electrospray ionization correct answer: -Also known as soft ionization -Species remains intact, form ions by attaching H+ (+1 amu) or Na+ (+23 amu) 3:1 correct answer: Mass spectrometry ratio that appears for Cl 1:1 correct answer: Mass spectrometry ratio that a...

Unsaturated fatty acids - have one or more C=C bonds Saturated fatty acids - Have no C=C bonds What are the ways that biodiesel is produced commercially? Which method is the predominant method? - 1) Base-catalyzed transesterification of the oil with methanol and one used in lab. 2)Acid-catalyzed esterification of the oil with methanol 3) Saponification of the oil to yield free fatty acids, followed by acid catalyzed esterification. Match the products and catalyst for the following tran...

attachment 5 2 .docx Can you please provide me with at least a 5-page review writeup based on a sample of CBD oil I ran some NMR experiments on: 1H NMR, 13C NMR without decoupling, 13C NMR with decoupling and 1H-13C HSQC. Please add references and use other articles not just the two articles I provided – there may be better ones that can answer the 4 main goals I am trying to answer for. It's important to note that the assignment and interpretation of peaks in the 1H NMR, 13C NMR with...
