Recent Tutoring Session Reviews
"The student and I focused on clarifying concepts in thermodynamics and working on practice problems from her worksheets. We discussed the collision model and how reactions go faster with increasing concentration and increasing temperature. We clarified that catalysts speed up the reaction by lowering the activation energy and the catalyst is not consumed. The student clearly demonstrated her understanding of exothermic and endothermic reactions. I gave the student some tips on how to organize and report her findings on questions that involve multiple steps. We also went over the strategy of using ratios to solve for unknowns. I also sent her some links to online resources that cover topics such as Hess’ law, enthalpy, enzymes, and activation energy. The student quickly understood all concepts covered and I am confident in her understanding of thermodynamics."
"This session is preparation for the student’s upcoming test. We reviewed heating and cooling curves, phase diagram, energy diagram and Gibbs Free energy. We also discussed calculating problems involving in these topics."
"We went over equilibrium problems in chemistry as well as the problems that I had assigned at the last session. We then assigned problems over the weekend to practice ideal gas laws so that we can reinforce the concepts."
"We went over balancing half reactions for electrolytic cells in acidic/basic solutions and drawing Galvanic cells. The student was attentive and responsive. He wasn't confident with balancing the half reactions before we started, but reached a point where he was comfortable with solving and understanding what was going on."
"During this session, electronic configurations, orbital diagrams, and periodic trends (electron affinity, electronegativity, ionization energy, and atomic radius) were reviewed in depth. Homework was also given (read chapters 3.8 through end of chapter 3, and chapter 4)."
"Today, we went over empirical/ molecular formulas and redox reactions. We first reviewed stoichiometry and drawing compounds. He got some of the methods mixed up and I reviewed them with a different step by step approach. Then, I went over redox reactions and explained how to balance with charges and understanding what's being reduced and oxidized. For next time, I will touch upon molarity."
