Recent Tutoring Session Reviews
"Today we reviewed three chapters for the student's upcoming exam. We started by reviewing polar and non-polar covalent bonds. She explained that she did not have a good understanding of these concepts, so I explained them in more detail. I also used an example to make sure she understood. Afterward, she was able to decipher between the two and give examples. I assigned to her several practice problems that required her to decipher between polar and non-polar bonds. I also told her to draw the Lewis structure of the compound and the polarity arrows in the right direction. She struggled with determining which compounds were polar and non-polar, so we went through each example together, and her understanding improved. I also asked her follow-up questions, and she was able to answer all of my questions correctly. Next we reviewed how to name compounds. I assigned her a mixture of ionic, covalent, and acid/base compounds to name and write the formula. She did fairly well with this task. She mostly struggled with naming acids, so I gave her a simple way to memorize the transition from polyatomic ion to acid. Later we reviewed intermolecular and intramolecular attractions. She was able to explain the differences and give me examples."
"We covered the electron cloud, shells, and various quantum numbers. We also went over how to order electrons."
"Today's session covered: balancing chemical equations, stoichiometry, limiting reactants, theoretical, actual and percent yield; and problems based on the those concepts."
