Recent Tutoring Session Reviews
"We covered content that would be on the students quiz. This content included: radioactive decay, stability belt, neutron to proton ratios, alpha decay, beta decay, positron emission, electron capture, gamma emission, half lives and half life calculations. The session started with a review quiz which he did fairly well on."
"We did some more in depth work with solubility today like predicting products and determining if a compound is soluble or not. The student is becoming more proficient at using her references tables to help her answer questions. We also did a few dilution problems using the C1V1=C2V2 formula. The student didn't find that formula difficult at all. She was able to do her practice problems with very little help from me."
"Today the student wanted to go over thermodynamic problems and how to solve them. In doing so, we discussed the different thermodynamic variables (enthalpy, entropy, Gibbs free energy) and how to determine these variables for a reaction given the mechanism, as well as with the formation values of each of the individual species. We also went over how to use specific heat and heat capacity to solve problems relating to temperature changes. Lastly, she wanted me to go over kinetics with her, including integrated equations. I showed her how to manipulate data, as well as the utility of the integrated rate laws in experimental settings."
"We worked through a worksheet provided by her teacher. The focus was calculating Gibbs free energy when given thermodynamic constants, enthalpy and entropy. We also worked on calculating the equilibrium constant when given the free energy value. In general, the student seems to be doing really well with this material."
"We went over a diagnostic test he did for homework. He scored a 60%. There were two areas that he needed a little more help in (ionization energies and hybridization) so we went over a few worksheets on those concepts. He showed great improvement on stating the hybridization of elements. I left him with another worksheet for homework to really stick the concept in his head!"
"The student and I discussed a wide variety of problems in preparation for his AP chemistry test next week. We covered questions related to exothermic vs endothermic reactions, ideal gas law, molecular geometry, stoichiometry, and redox reactions. The plan is for the student to go through some of the practice problems in his review AP Prep book, taking note of the particularly challenging ones so that we can discuss them later. We also discussed different topics for his AP calculus test. We covered how to take derivatives, evaluate limits, and calculate integrals using u-substitution. We also focused on using derivatives to estimate errors."
"The student and I reviewed kinetics, acid-base equilibrium, and organic chemistry in our session. We practiced these topics using problems in the student's AP Chemistry book. He reviewed writing rate constant expressions for mechanisms and solving pH problems for polyprotic acids. There were no concerns from this session."
"We reviewed a lab on oxidation/reduction titrations. I then explained some concepts in organic chemistry. We then did some questions and went over how to calculate the PH of acids and bases and how to balance redox equations."
"We went over a previously taken practice test in preparation for the AP exam. We went over questions involving solubility, conductivity, limiting reactants, acids and bases, semiconductors, and partial pressures. Overall, the student seems to be well-prepared for the AP exam so far."
"The student's final exam is next Tuesday, so she and I went over free response questions from previous AP Chemistry examinations. I believe that with additional study, she will be ready for her exam. In the meantime, I will be creating multiple choice question reviews for her to study."
"AP Chemistry - chemical nomenclature, chemical thermodynamics, molecular geometry, types of chemical reaction review."
"The student and I went over practice multiple choice and free response questions for the AP exam and reviewed some concepts such as acid/base titration, periodic trends, limiting reagents, and stoichiometry."
