Recent Tutoring Session Reviews
"Today's session began with a quiz with a 5 part problem from the chemistry exam. The quiz covered: molar mass conversions, stoichiometry, Gibbs Free Energy, entropy, enthalpy and Heat of Formation. Today we covered the three ways to solve heat of formation problems: Hess's Law, standard state and heat of formation. We also covered enthalpy and worked problems of all the topics. Today was a very productive session and the student felt very comfortable about the material."
"Today we prepared for the student's exam that she has at the end of the week. We reviewed the basic concepts of stoichiometry, in regards to chemical reactions. From there, we discussed limiting reagents, and different problems in which it can be used. We also discussed percent yield, and different ways in which it can be used, with regard to actual and theoretical yield. We also worked on a worksheet, in addition to textbook problems."
"In today's session, we went over thermochemistry, bonding, periodic trends, and the electromagnetic spectrum. I outlined a review on these topics, and also followed along with practice exercise problems. Within each subject, I covered topics such as, change in enthalpy, in calorimetry at constant pressure, and constant volume conditions; trends concerning electronegativity, energy of ionization, electron affinity, and atomic radius; also bonding energies, such as when bonds are formed and broken. Overall, the student seemed to understand and grasp the concepts well, she also tackled the practice problems accordingly."
"We did a big review for the AP exam. We went over a wide variety of subjects, but focused on titrations, equilibrium, and electrochemistry. We went over practice problems from the book, and multiple practice problems from the web site. We also went over strategies for time management on the test, and ways of approaching problems on the non-calculator sections. Overall, the student seems very well-prepared for the test."
"I helped the student prepare some of his assignments for Chemistry--he needed help figuring out 2 free response problems (multiple parts to each). We looked up similar questions and verified what steps were needed in order to obtain the correct answer. Right now he is working on thermodynamics and limiting reagent/reactant, as well as finding mass, moles, pH of solution, etc. These questions are pretty difficult but he is working on gaining understanding and showing his work with unit cancellation."
"Reviewed homework packets covering topics ranging from chemical structures to electrochemistry. The student managed to complete all packets except for the last sheet, which he managed to get 3/5 of the way done on and will finish before turning in."
"We went over a lesson on electrochemistry (electrolysis and voltaic cells). I had the student do a worksheet on sample multiple-choice questions dealing with electrochemistry. I also had him do some long response questions for electrochemistry taken from previous AP Chemistry exams. He scored almost full points on all the long response problems. He will continue to work on writing down EVERY step and rechecking his numbers to make sure he has written down the correct numbers."
"The student and I covered galvanic cells; he seemed to grasp it pretty well. We went over a number of questions together, and also strategies on how to solve certain problems like Roman numerals and calculations."
"The student and I discussed concepts and practice problems related to titration, Acid-base chemistry, Redox reactions, and Buffer pH calculations. He still has more to practice in his AP Chemistry test prep book, but he seems ready to take his test on Monday."
"The student and I did a final review for the AP Chemistry exam. She has notes from the few problems she missed or guessed on for her final exam so we reviewed those and clarified how they would be solved. I also gave her some quick reference study guides for important concepts. We then worked through a free response question from the test that covered a bunch of different topics."
"The student and I met to go over a last minute packet his teacher assigned. We worked on many things, including ionization energies, wavelengths, boiling points, orbitals, bonding, etc., depending on the question. He did well with prompting. He needs to review all these concepts again (which was probably the point of the packet) before going in for the AP test."
"Today the student simply wanted to do practice problems for the AP chem test, with an emphasis on acid-base problems. I first had her do practice problems from the practice book as a warm up, as these questions mainly utilize the equations she is given to solve for pH (such as by using Henderson-Hasselbach). Following this, I gave her much more difficult problems from college classes that involve finding pH at various concentrations of strong/weak acid and base mixtures. As an example, several strong acid/weak base questions were asked with varying concentrations to see if she could find the pH at these different concentrations. These problems were also explained from a conceptual point of view. She found these problems very challenging and required assistance on many of them. These problems were also very difficult, so that was expected. We will have one last meeting go over this material once more. For the difficult of the questions generated, the student did reasonably well."
