Recent Tutoring Session Reviews
"We worked a few practice problems that were from her textbook. I was able to find her the complete solution to the Ostwald process so she can look at that and go over the problem. I also gave her some extra practice problems that have the solutions so she can do some extra practice."
"The student and I went over chemical kinetics and reaction rates. I let her know at the beginning that this would be a more difficult concept. I did my best to explain the material in different ways. I believe she is understanding rates and rate laws a little bit better. I gave her many practice problems with solutions to do on her own after we did a few together, and they seem to be helping her understanding of chemical kinetics a lot."
"For our first session, our main focus was drawing out the structure of compounds based on their chemical formulas, then drawing all their resonance structure, and assigning formal charges. We also went over VESPR, which is basically predicting the molecular geometry of such chemical structures. She is a very bright and ambitious student, and should be able, I predict, to improve her grades soon after three more sessions or so at the most."
"The student and I reviewed for his upcoming test, which covered the properties of gases and the gas laws. The most challenging problems were those that required the use of stoichiometry in combination with the gas laws. We reviewed the concept of limiting reactants and how to use the information of limiting reactants to determine the amount and mass of gaseous products. The last part of the session was spent on reviewing the basic graphs of sine and cosine graphs with vertical shifts and reflections across the x-axis."
"Today we spent our session introducing some new topics in molecular bonding that the students have notes on, but have not yet covered in their class. We talked about the spectrum describing the character of bonds from pure covalent to pure ionic, and spent some time to introduce Lewis Structures and how they're used to predict molecular geometry and polarity of molecules. The students also spent a few minutes aside to talk about their lab report which requires them to find the percent composition of a brass sample they dissolved in nitric acid. After they walked me through the steps that they performed in lab, I was able to confirm their method for finding the amount of copper present in the sample from the absorbance of copper ions in their resultant reaction mixture. I also briefly introduced the terms of resonance and formal charge. We will continue working on their assignments and understanding these topics next week."
"The student received her review pack for the exam that is in a couple weeks. We began to go through it together, focusing on the free response sections. We are continuing to work on her ability to articulate correct answers using correct vocabulary. We have also discussed various study tools for memorizing some of the fundamentals (valence shell configuration, polyatomics, periodic trends). She will get through as many of the multiple choice questions as she can before our next session, and we will review together, making note of the areas she needs the most support."
"Thermochemistry, thermodynamic. We went through and review the main topics in thermochemistry and solved the problems together. I suggested more reading materials and problems solving for her. She needs to do more of this, and we will work on that next session as well."
"We went over mole to mass conversions, Avogadro's number, and mass percent calculations. We also touched upon empirical formula calculations, but we will work on that in more detail next class. She has a test on Tuesday that will cover all these topics."
"The student took another quiz covering ion names/formulas. We started going over ICE charts. I showed her an alternative method to determining the LR, ER, and remaining reactants. She seemed to understand this method better and did well working on a second problem. I brought supplemental problems that reviewed concepts from a few weeks before."
"In this session, we reviewed molecular and electron geometries, along with hybridizations. This was done through the lens of making the Lewis structures of various compounds, then identifying what the geometries would be, and the hybridization of the central atom (when applicable). At the end of the session, for review, we went over many of the common polyatomic ions to solidify and speed recognition."
"In this session, we started going over a review packet for his final exam. We went over finding the amount of grams of a substance are present in molecules, the mol ratio of elements in compounds, and other review materials. He had a good understanding of the topics we covered after we concluded."
"We went over the student's study guide for his final. He knew a lot of the answers from his study guide but did not know the reasoning and chemistry behind the questions. I helped him understand the trends of the periodic table. He understood the material very well towards the end. He has his own study guide to practice from. Overall, this session was great!"
