Recent Tutoring Session Reviews
"Today, we covered topics that the student thought she needed to reinforce for her upcoming final. These topics included nomenclature, relative abundance of isotopes, polyatomic ions, and molar masses."
"The student has a chemistry exam this Thursday, so we first cleared up questions from her worksheets and then covered topics that had not been reviewed during our prior chemistry tutoring session. First, we reviewed practice problems regarding the conversion of mass to moles to number of particles (atoms, molecules, etc.). We focused on understanding the global question first before diving into solving the problem. This included writing out conversions and units prior to inputting numbers and doing calculations. The molar mass can be used to convert between mass (in grams) and moles. Avogadro's number can be used to convert between number of particles and moles. The volume of a gas at standard temperature and pressure (STP) can be used to convert between moles and volume. I also strongly encouraged her to always include units for every value used in order to keep track of which units can be cancelled during calculations and which units are used to report the answer. Next, we reviewed general concepts regarding ions in solution, precipitation reactions, solubility rules, and net ionic equations. I suggested that she finish her worksheets, study with her flashcards, and email me with any questions that come up as she finishes her review for the test."
"We continued to review stoichiometry problems. The student still needs a lot of work to complete these problems on a test in an efficient time."
