In this video I teach the concept of the time of flight mass spectrometer and how to solve time of flight calculations. I show you how to answer any question you may be asked on how the mass spectrometer works using VIADD and how to rearrange the TOF equation and solve the two major types of problems you will encounter in TOF problems.

In this video I teach the concept of back titrations. I show you how to complete any back titration you may be asked on your exam using a simple diagram. Then I shows you how to complete the two major types of problems you will encounter in back titration problems. One in acidic media and one in alkaline media!

In this video I explain the conjugated pi bond system found in benzene using hybridization theory so that you understand the chemical reactivity of benzene. I explain how to name arenes which are compounds that contain benzene rings. And I also explain when to use benzene and when to use phenyl when naming arenes.
