Recent Tutoring Session Reviews
"Today we covered: alpha decay, beta decay, electron capture, gamma and positron emission and began IUPAC organic chemistry nomenclature. The student has a quiz coming up on Tuesday so the next two sessions will be focused on preparing for his upcoming quiz. I have no concerns at this time. He is handling the material quite well."
"The student and I reviewed acid-base titration problems, hybridization, kinetics, and molecular orbitals in our session. We used practice problems to illustrate each of these topics. She is reviewing the concepts that she has the most difficulty with before her final and AP exam. No concerns were noted."
"Today the student wanted to go over questions from her AP chem prep book, starting with nuclear and atomic phenomena. This included questions on electron configurations and periodic trends including metallic character, reactivity in water, electronegativity, electron affinity, and ionization energy. We began discussing covalent and ionic bonds, answering questions on these subjects. She needed guidance occasionally with questions, but when given guidance was able to integrate the new information given to her quickly to answer the question."
"The student is really struggling with balancing reactions and predicting products. We did a lot of practice balancing reactions and I showed her a method to hopefully make it easier for her and also will help check her work to make sure its right. I told her to separate each reaction by element and count the number of each element on each side of the equation. Every time she added a new coefficient I explained that she should count again. This way she always knows how many of each element she has."
"The student will be taking a full practice AP exam on Monday. In preparation, she took a practice exam by herself and wanted to review some questions that she missed. For the gas law problem that she missed, I showed her a method that works for all gas problems, no matter which properties are at play, which she was able to use successfully immediately. Beyond that, the rest of the session largely consisted of catching minor errors and clearing up minor misconceptions. Her preparation for the AP exam in a few weeks, I would estimate, is fairly strong."
"In this session, we continued to work through the same chapter from the previous week, electrochemistry. I went over conceptual topics such as the rusting or corrosion of Iron, metal plating, and electrolytic cells. In addition, we also covered necessary equations and constants she would be using and how to derivate conclusions from the information given about electrolytic cells. Then we went over some practice problems in her book to solidify the material- using conversations to calculate. I felt she had a good understanding of the material. I asked her to read through the chapter to make sure she grasped the conceptual topics well."
"Today's session was dedicated to learning about elementary steps in a reaction, and how they can be used to find the rate law. After a brief review of kinetics, we jumped into predicting the products for reactions. After giving a couple of tutorials on how to write out balanced reaction, ionic reactions, and net ionic reactions, I began to let the student determine the products for specific reactions. He has improved his nomenclature skills."
"The student and I went over gas law problems and concepts, and she has an excellent understanding of the problems. Her final exam for this class is next Tuesday, so she and I will continue to prepare for it. In our next session, we will be looking at free response questions to increase her conceptual understanding. We went over a review that I made, and she was usually correct when she went with her intuition."
"The student and I continued reviewing the toughest and most often covered concepts on the AP Chemistry exam, in preparation for the test. He is particularly struggling with acid and base chemistry so we went through the major concepts again and practiced doing the problems in the book. We talked about weak vs strong acids and bases, Ka and Kb and Kw, as well as pH and pOH. We practiced finding the pH of various weak acids, strong acids, weak bases, strong bases, polyprotic acids, and mixed acid solutions. At first, the student was rusty on these concepts, but he got the hang of it pretty quickly, and I think that he will be able to correctly answer any acid or base question on the AP test. We will continuing reviewing tough concepts next week!"
"During this first session, lab reports were completed, including the Thermodynamics lab and Hydrolysis lab. The student mostly understands the material, though is inexperienced in using the equations and finding solutions using them (minor issue). This can be remedied by assigning homework or extra practice problems before the next exam."
"We began covering older topics for the AP chemistry exam. This time, we focused on thermochemistry. The student still had a good understanding of this section. We also went over the diagnostic exam he took. He only missed a handful of questions, and we covered the mistakes. He will take a practice exam before our next session."
"The student had a series of questions from practice AP chemistry tests, so we methodically worked through these. Subjects includes stoichiometry of reactions generating gases, Gibbs Free Energy and how it determines spontaneity, rate laws and the Arrhenius rate equation and how it shows that reaction rates are directly related to absolute temperature and inversely relate to activation energy."
