Recent Tutoring Session Reviews
"The student and I went over the basics of solution chemistry. We went over a worksheet she got in class by her instructor, and problems based on molality, freezing point depression, and boiling point of elevation. The student is a very bright girl and is eager to do well. I reiterated the equation of figuring out moles because that is a fundamental that is repeated throughout chemistry. I look forward to working with the student again."
"We prepared for his upcoming final in chemistry. He has a good grasp of most of the recent topics and calculations involving mole conversions and radioactive decay, but he needed to refresh his understanding of earlier topics such as molecular geometries and intermolecular forces."
"We covered gas law problems in order to prepare the student for a test. We primarily focused on equation manipulation in order to algebraically solve problems. I showed him some modified versions of the ideal gas law that involve molar mass and density, and we worked through problems on the study guide. That went fairly well, once he saw how an equation needed to be manipulated, she was quickly able to solve the problem. We also discussed when to use different laws. He requested that I try to find some problems for her that involve the explanation of concepts in order to solve them (i.e. essay-type questions). She has a test Thursday over this material, and I will try to find her sample problems of what she requested by tomorrow night. I left her with video links to some barometer/manometer example problems because she said those were not covered in class due to snow days."
"We went over conversions from moles to grams, liters, and molecules. I drew a conversion graph that she said was very helpful and which she will be using to memorize the conversions between the different units. We also worked on a web assignment which spoke about percent composition and empirical and molecular formulas. I explained all the concepts to her so she would be able to complete the assignment and spent time teaching her how to do the problems. She should be well prepared for the subject matter when her teacher goes over them."
"The student and I did a comprehensive review of all things chemistry for a general first semester chem class. He understands everything and should do well."
"The student had a test the next day for chemistry, so we reviewed chemical equations, types of reactions, balancing and writing out equations. In the first we just rewrote the word version of a compound into its chemical form. In order to focus on the special rules and concepts behind the reactions, I told him he should make flashcards with each element/ion with the chemical sign and charge on one side, and name on the other: that way he could physically rearrange the elements for a chemical reaction. For each reaction we completed "fill-in" chemicals and categorized the reactions and differences in reactivity."
"The student and I worked on homework problems with dimensional analysis. We discussed moles, mass, and particles."
"The student has an exam on Thursday, so she had a practice exam, given out by her teacher, that we worked through. The topics we covered were atomic structure, subatomic particles, isotopes, interrelating mass number, atomic number, atomic mass unit, neutrons, protons and electrons and how to identify unknowns given certain knowns, like energy levels, ions vs atoms, net charge. We finished the review, and she definitely knows this stuff."
"We went over some problems on a worksheet. It was about thermodynamics, thermochemistry, and the heating curve for phase changes. We solved some problems together for her coming test."
"Today, we reviewed for the student's quiz. Topics included were AMU, mass, molecule/atoms, and moles. She was also required to know how to convert between them."
"Topics covered: 1. Stoichiometry and determination of weight to moles. 2. Conversions using molecular weight. 3. Review of balancing equations."
"We went through her review for her exam. I explained how she can set up each questions. She is doing well and understands what she is doing."
