Recent Tutoring Session Reviews
"We covered nomenclature and writing formulas for binary ionic compounds, including polyatomic ions."
"The student and I reviewed stoichiometry for his test on stoichiometry tomorrow. He was proficient in converting between grams, liters, and moles, but he needed a bit of practice with limiting reagents. By the end of the lesson, he could successfully identify limiting reagents and use this information to determine the amounts of reactants left and products produced. We worked on multiple problems from his review packet together, as well as my own problems."
"We covered topics such as quantum numbers (n, l, ml, ms), periodic trends, and valence electrons, and we then went over practice problems."
"We covered mostly stoichiometry (moles to molecules to mass). The student was struggling with the concept of the mole and remembering how to do conversions. He was generally enthusiastic to learn the material. We covered some strategies for setting up problems."
"Today we went over questions covering kinetics. We look at rate law, integrated rate law, half-life equations, and graphical representations of zero, first and second order equations. We talked about the definition of a catalyst and an intermediate. We also went over the Arrhenius equation, what it means and how to use the equation for catalyst problems. Overall, the student was able to grasp the concepts better after our session and we will continue to work on these types of problems in future sessions. Great job today!"
"Current topics in the student's class are drawing bonding Lewis structures and recognizing standard bond angles. I showed him some rules for drawing bonding Lewis structures, and provided a numerical approach for finding the number of bonds in a molecule. With a little practice using the new method, he was able to draw correct structures much more easily. We then progressed to understanding molecules as 3-dimensional structures, and based on the principle that electron pairs repel each other, I was able to explain to him why molecules have specific angles between their bonds. He reported his most recent test score and semester grade, earning his goal of a B on both."
