Recent Tutoring Session Reviews
"Today, the student and I continued with reactions and balancing equations. To guide our study we used her textbook, study guide for a prior test, and the prior test itself. She would like to do more practice with balancing equations, so I will email some additional materials. We also reviewed ionic, covalent, and metallic bonds, and intermolecular reactions, by re-taking her prior test. Her performance tonight indicated that were she to take the test again for credit, her grade would be significantly improved. I've encouraged her to review concepts including electronegativity and the VSEPR model configurations. For our next session on 3/7 at 10:30 AM, she and I will discuss four questions, one of which she will encounter on her upcoming test, and come up with solid responses. In addition, we will continue with stoichiometry and gas laws."
"We covered quantum chemistry, (No Suggestions) principle, Hund's rule, electronic configuration, etc. We also covered periodic trends with some rationale for their existence. The student did some homework problems and reviewed for test on Friday. Everything seemed to go well with no major hang ups."
"We covered ionic and covalent bonds and the "continuum" in the spectrum of electronegativity differences. We started with a simple Lewis dot structure and talked about octets and the valence shell. Then we discussed formal charge and how to calculate formal charge for each atom in a molecule. We made an important distinction for when you count electrons in a Lewis structure. We then did some hard Lewis dot structures and discussed again the importance of 1) a full octet and 2) formal charge and how you count electrons differently for these two things. This led into a discussion of resonance structures. The student is working through the hard problems, and I feel like we made a lot of progress on Lewis dot structures today. She has a test in a week, and she has a long way to go on her own. I asked her to practice a lot of Lewis dot structures, read the book, and review periodic trends/effective."
"The student and I did a review of her test, and an introduction to molecular geometry. She initially didn't understand the theory behind molecular geometry vs. electron domain geometry, but before we were done, she was clear on it."
"For today, we worked on a worksheet covering gas stoichiometry. The problems we went over were very extensive, and integrated several concepts covered prior, such as balancing equations, gas laws, vapor pressure, Dalton's law, combustion reactions, empirical/ molecular formula determination, and gas density. Overall, the student did well in the problems, proving to be adept at identifying the pertinent steps and formulas to use based on the information that questions present. He does make occasional calculation errors, and is encouraged to continue reviewing his work to check his calculations as time permits in tests and quizzes. He informed me that he will be taking a quiz tomorrow covering the concepts we reviewed in today's assignment."
"The student practiced naming acidic compounds, mol to mol conversions, Avogadro's number and basic stoichiometry. He had minor misconceptions about the content but we addressed those. I suggested that he completed the upcoming extra practice because their current unit is known to be difficult."
