Recent Tutoring Session Reviews
"We are continuing to review chemical bonding, as well as the Lewis dot structures, and the idea of valence electrons and how to calculate the number of valence electrons. We pulled many examples and the student worked them and drew Lewis dot structures for them. We then discussed the VSPER theory, bond angles, bond shapes, electronegativity, polar/non-polar bonds and polar/non-polar molecules. We then discussed examples of this concept and what this means for polarity."
"I was contacted to help the student due to an upcoming chemistry test. We quickly went over what we worked on last time, but moved on to the new topics he is covering in class (gas laws). I noticed that he definitely understands what is being taught."
"We reviewed all of the student's material for his test tomorrow. He feels much more comfortable with all his class material going into tomorrow's exam. He was able to perform the hardest level problems along with me and get the same answer. The topics we covered were balancing combustion equations and the amount of product produced, and determining molecular formulas from its empirical form."
"This was a good session. The student is now dealing with reactions in aqueous solutions and ionic reaction yields. We looked at mole to mole, mass to mole, and mass to mass calculations. I color coded all of his notes and homework. Mole to mole conversions are based on the coefficients in the balanced chemical equation. Mole to mass conversions are based on atomic and molecular mass provided by the periodic table. Mass to mass are three step equations requiring both other conversions. We looked at limiting reagents, excess reagents, and deriving reactants from product/yield quantities. We will look at theoretical, actual, and percent yield next session."
"The student had a review for her class that we worked through. It covered types of reactions, stoichiometry, limiting reagents, ionic compounds, and balancing chemical equations. She seems to be coming along very well. I will be sending her some more problems so that she can get more practice."
"We worked through some of the problems at the end of chapter 6 in his textbook as he is currently learning the material in lecture. He is really determined to do well in this course so that he does not have to take two other chemistry classes in future. He has promised to dedicate about an hour a day of his own time to work on end of chapter problems as practice. We will also be going through end of chapter chemistry problems and homework problems together in session."
"Covered the concepts of molarity, molality, solutions (solvent/solute), saturated, supersaturated, miscible/immiscible, high/low vapor pressure, dilutions. Completed worksheet on Chap. 16 in textbook. Discussed real world applications."
"Covered quantum chemistry, Aufbau principle, Hund's rule, electronic configuration, etc. Also covered periodic trends with some rationale for their existence. Did some homework problems and reviewed for test on Friday. Everything seemed to go well with no major hang ups."
"During this session I helped the student with a new topic in her chemistry class of the ozone layer and climate change. This involved reviewing the chapter and doing various problems. We also reviewed her previous quiz taken and determined what she got wrong and why. We then redid the quiz for an opportunity for Her to gain points back."
"We covered entropy, enthalpy and thermochemical reactions extensively. The student was mainly struggling with interpretation of multi-step problems and combining of enthalpy of formation problems. The student took well to the material but was still working to grasp the concepts. I will address this in the next session. I left her with their practice worksheet in order to continue with developing an understanding."
"During this session we focused on finding specific problem areas. The student identified several areas that he struggled with such as, stoichiometry, moles, molarity, solutions, solutes, etc. I reviewed some of his past exams and worksheets and asked him questions to get an understanding about specific focus areas. After discussing strengths and weaknesses we examined some online resources that were provided by his teacher. I suggested he purchase a chemistry book and workbook to help with our sessions and independent study. I also suggested that he review his teacher's online notes after class to get a better understanding of the concepts. Next I assigned him a brief quiz that focused on moles. He did really well on this exercise after I gave him brief assistance. We also reviewed stoichiometry concepts and looked at some common mistakes that he made while answering these questions."
"Today we went over some of the same material as our last session about stoichiometry. Although she didn't remember all of the topics we covered from last time, this session went a lot quicker since she seemed more familiar with stoichiometry overall. Everything went smoothly."
