Recent Tutoring Session Reviews
"The student and I covered entropy and Gibbs free energy calculation, and then did a review of acid-base, solubility, buffers, and titration chemistry."
"Tutoring went well today. We reviewed the topics from chemistry and focused on what makes a buffer a buffer. We talked about why buffers resist change in pH. We reviewed some key terminology including buffer, salt, and k equation (product over reactants). We finished by covering organic chemistry reactions involving alkenes. We reviewed hydration, dehydrations, halogenation, dehalogenation, hydrohalogenations, and Markovnikov addition. We covered electron donating and electron withdrawing groups with benzene."
"Today we reviewed the remaining ten questions on the practice final exam. After I had the student complete two additional Hess' law practice questions, we discussed the three main types of cubic unit cells. Specifically, we reviewed how to determine the number of atoms within each type of unit cell and how to calculate the density of each type. We also covered how to calculate the heat required to raise the temperature of a substance and to change a substance from one phase to another. Furthermore, we talked about intermolecular interactions, Graham's law of effusion, rms speed of molecules, and the van der Waals equation. At the end of the session, we discussed her studying plan for her final tomorrow. I advised her to complete as many practice problems as possible, with emphasis on her weakest topics, and also to review her previous tests. She expressed that she had a good basic understanding of most of the topics, and with plans for additional practice this afternoon, she felt better about her preparedness for the final."
