Recent Tutoring Session Reviews
"During this session we went over moles, mole conversions, gram formula mass, empirical formula, molecular formula and stoichiometry. We went over questions in the student's book. Overall this session went well."
"In order to prepare for the exam we looked over chemistry concepts such as electron configuration, periodic trends, ionic and covalent bonding, and balancing equations. The student is very receptive and picks up material quickly."
"The student and I discussed how to name and draw isomers. We spent the majority of our time naming isomers and hydrocarbons. We also discussed drawing structural isomers once a molecular formula is given. The student had a very positive attitude towards the material."
"We first worked on oxidation states and determining the oxidation states of elements in a compound. Once she understood that topic we moved on to looking at half reactions and using oxidation states and half reactions to balance redox reactions. We broke everything down into the steps required to do the problem. We then went over a few Ideal Gas law problems and some stoichiometry. I think the student got a lot out of the session and appreciated everything being broken down for her. She now has a good grasp of how redox reactions work."
"Today we covered several concepts in thermochemistry. The majority of the questions involved the heat of formation and Gibbs free energy. We worked through combustion and other types of reactions."
"Today the student and I worked on her lab report that required her to plot a graph of temperature vs. pressure. She needed to show on her graph the relationship between temperature (expressed in Celsius) and pressure (expressed in kPa). After plotting the graph, she was able to extrapolate the data to absolute zero value. She was also able to show that pressure/temperature equals a constant under the conditions of the experiment. There were some conceptual questions regarding molecular velocity of gases and how temperature affects pressure. Finally, I reviewed some of her homework problems related to combined gas law equations."
"The student is preparing for his first test since his midterm, and we went over what he thought would be on that. He has also started learning how to balance chemical equations, so we spent most of the time going through practice sets. he quickly picked up the concept behind this and he really excelled by the end. We concluded the session by working on his lab that was due this week and went over different types of chemical reactions."
"The student and I had a great session. She had questions about electromagnetism and electromagnetic radiation. We talked about some of the basics involved with electromagnetism and worked through several examples using the formulas. She also worked through a more complex problem from her thermodynamics homework."
"In this session, we reviewed percent composition of compounds, before moving on to empirical and molecular formulas. The material was fully explained before attempting fully-worked-out examples. After the student became comfortable with the material, I showed her a short cut. Chapter 10 is now finished, and chapter 11 (chemical equations) was introduced."
"Worked on a homework assignment on heat of fusion, heat of vaporization, heat of formation, and applying Hess' Law. Unfortunately, there was no time to work on the test review packet, but the student knows she can e-mail me with further questions. Working on the homework instead was beneficial, because many of the topics hadn't been fully covered in class, so it gave her the opportunity to gain a better understanding of the material. Furthermore, she seemed to have an easier time assimilating the concepts this week than she did last week."
"We worked through a lab write up determining the molar volume of hydrogen gas. We also covered material that may be on a quiz, which involved using the gas laws to find changing temperature, volume, or pressure."
"I helped the student with the concepts of intermolecular forces, including the topics of ion-dipole, dipole-dipole, hydrogen bonding, and London dispersion forces. We covered the reading from his textbook and I answered his questions from the reading. I helped him with the questions from his lab worksheet and we also covered some practice questions from the book. At the end of the session, he told me I helped him understand the concepts a lot better. Great session overall!"
