Recent Tutoring Session Reviews
"The concepts covered in today's session included: anhydrous salts, calculating empirical formula, molecular formula, molar mass, and percent yield. This session was scheduled for test preparation in the chemistry lab class. We covered assigned labs and homework."
"First I spent a little over an hour reviewing with the student chemical reactions, the five classes of reactions (combustion, synthesis, decomposition, single replacement and double replacement), how they could be identified and what their standard formats were in preparation for a test on Monday. The student picked up the details quickly and was able to correct his own worksheet. Then I spent the remainder of the time with the student, reviewing hydrates, ionic compounds which have water molecules locked inside their crystal lattices, which cause them to have different physical properties but the same chemical properties as their an-hydrated forms. The student has been keeping up well with molar mass and unit conversions and so was quick to pick up the simple math of how to calculate the hydration ratio, the main question type of the chapter, and is confident that he will succeed in his test tomorrow."
"We went discussed the basics of chemical bonding, balancing of chemical equations, and also completing chemical reactions. The student wrote notes, and I used actual drawings of molecules to help visualize the concept of chemical bonds and what molecules look like. We used stepwise methods to characterize chemical reactions to completions and also stepwise methods for balancing chemical equations."
