Discussion: In our experiment, we saw a relatively average percent recovery of 56.1% when hydrogenating the Triolein. We were then able to calculate Triolein to be the limiting reagent in the experiment based on the fact that it produced fewer moles of product as opposed to cyclohexene. From this information, we were able to determine that our experimental

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
