Recent Tutoring Session Reviews
"The student and I worked through a variety of problems that required the use of the ideal gas law. I broke down the basic concept behind the majority of the problems (always convert to moles, determine total pressure, use PV=nRT) and showed her a couple tricks that will allow her to complete problems quickly. She had the most difficulty determining when to use total pressure versus partial pressure. After showing her examples of when to use each, she was able to correctly complete example problems. I found a couple more of the difficult problems in her book and explained how to solve them. We spoke a little bit about her progress in math and she said she feels confident in the subject. Next lesson we will concentrate on prepping for her makeup exam in math."
"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 harder level problems along with me and get the same answer. The topics we covered were calculating what reagent was in excess and by how much, 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 I expect."
