Recent Tutoring Session Reviews
"The student and I continued his long problem set on the ideal gas law. Since it was basically a continuation of what we did last Friday, he did well and seemed to know how to set up almost every problem. The next topic we are going to work on is kinetic energy and diffusion of gases."
"We are going over: molarity, neutralization, and acid-base reactions. After laying the foundation with some concepts, we launched right into solving problems. I am having the student memorize and recognize certain chemical compounds, so I gave her that list. We started with some challenging problems. She was able to get through them. We are meeting again this Monday to follow up on how well she knows the problems."
"The student is studying molecular shape, the VESPER model and hybridized orbits. We spent most of the session discussing hybridized orbits and rules for determining hybridization. We reviewed her problem set on this topics. She did great on this subject after we discussed hybridization."
"Today we worked more on acid-base chemistry. The topics covered included the same ones from last session, as well as integrating these with concepts of salt solubility (the common ion effect, predicting the pH of a salt solution, etc.). After a short time struggling with net ionic equations (and the interface of her online homework system!), she was soon getting correct answers to nearly all the questions."
"During this session, the student and I went over multiple concepts that she needed to review for her upcoming test. We reviewed dipole moments, VSEPR, endo/exothermic, wavelength, ionic bonds, and Lewis dot structures."
"We reviewed balancing equations as well as predicting products of different reactions. We reviewed synthesis, single displacement, double displacement, decomposition, combustion, and acid/base reactions. He applied these concepts by completing practice problems in the review packet from class."
"The student and I covered concepts related to chemical kinetics, deriving integrated rate laws, and using these laws to find the rates of reaction and the concentration or number of moles left in a reaction. By the end of the session, he seemed really confident that he not only understood how to use the equations but also understood where they came from and why they work from a mathematical and conceptual point of view."
"We went over equilibrium concepts and how to solve for Kp, Kc, molar concentrations, etc. We talked out a lot of the conceptual ideas that were unclear about solutions and the meaning of equilibrium. We also thoroughly went over 4-5 calculations regarding equilibrium constants."
"We began to work on homework assignments due next week. We completed 2/3 of the assignments, which focused on intermolecular forces of liquids. She quickly grasped the concepts as we worked through the problems. We made a plan to meet next week so that we can work on an AP test question packet that will be due and begin to prepare for her midterm."
"The student has started a new unit involving half-reactions and electrochemistry calculations. He has a series of 4 sheets with specific questions from those sheets that he'd been assigned to complete. As he worked on the problems, I answered questions and checked his work. Topics included determining anode & cathode, Re-dox half reactions, determining potential for a system (E knot), and Gibbs free energy."
"We went over bonding and VSEPR theory. I showed the student a more efficient way of figuring out formal charges on atoms based on the atom's ideal number of bonds. We also went over resonance structures and some common resonance patterns, including what types of resonance structures are favored. We went over the background behind VSEPR theory and how to figure out the shapes of molecules with lone pairs. We also went over how to figure out the hybridization of an atom. Overall, the student showed a great deal of improvement."
"Tonight, we went over reading oscilloscope displays, specifically reading the time value off the horizontal axis and finding the period and frequency for sine waves, including phase angle."
