Recent Tutoring Session Reviews
"This last session before the student's final was spent entirely on Valence shell electron repulsion theory, and using regions of electron density to predict molecular geometry. He was able to visualize the three dimensional shapes very readily, and after some clarification of what was "pushing" or "pulling" groups one way or another, he was able to complete the review worksheet handily. We then finished with discussion of heavy metals, and why transition metals often have multiple stable ionization states. Overall, he feels extremely confident in his math abilities, and very confident in his understanding of the chemical concepts, opinions which I share. It has been an absolute treat to work with him this last semester, and I look forward to providing as much help as he might need for the rest of the school year."
"We focused mostly of the test pertaining to molecular orbitals, electron configurations, and molecular geometries."
"I met with the student after her break. We reviewed phase changes and intermolecular forces and went through her homework. Focused on electronegativity and polarity. It was an overall good session!"
"We covered molarity, molality, mole fraction, and some of the calculations associated with it (for example moles of solute given molarity and volume and dilutions). I gave him the strategy I give my own students which is to use either molarity x volume = moles for simpler problems or molarity1 x volume1 = molarity2 x volume2 for dilutions. We then did one or two problems using the concept of molality and colligative properties."
"Today, we covered concepts related to solubility and introduced terms including solvent, solute, saturated, unsaturated, and supersaturated. We used solubility charts to determine how much of a compound will dissolve into water at a given temperature. We also utilized solubility tables to determine whether or not a given compound will be soluble in water. The student will need to spend some time going over some of the course content that has already been covered previously in the class in order to master the current material. That being said, she was quick to pick up on all concepts introduced to her, and it will not take long to get her caught up to where she needs to be."
"Today, the student and I covered the material for her upcoming test on Tuesday. Her test is on petroleum. We covered hydrocarbons, intermolecular forces, and naming organic molecules. We also did the practice problems at the end of the chapter. She has a very good grasp on the material and she should be ready for her test if she continues the good work. I told her to continue making her outline and keep reviewing before the test. She got a 100% on her last test, which we are both very happy about."
