Recent Tutoring Session Reviews
"Tonight we talked about rotational kinematics. The student was struggling with all concepts in general so we started broadly and then tried to focus on specific problems at the end. We went over general strategies which can be applied to all problems and then spent the majority of the time focusing on torque and moment of inertia."
"We covered ideal gas law and derivations. This included concentration and density. We also went over determining the concentration of an ionic solution. The student had a good attitude. He will continue to work on his homework problems. We went over steps to approach these kinds of problems."
"We started by looking over the most recent material from Unit 7. We talked about saturated/unsaturated/supersaturated solutions and how to determine which is which. We also looked at solubility curves for different substances. Remember, the line represents saturation and anything below is unsaturated and anything above is supersaturated. Dissolving a compound in solution is a type of chemical reaction and is therefore either endothermic or exothermic. Solids dissolving are often endothermic, while acids, bases, and gases are typically exothermic. The heat of solution tells us whether a reaction will be endo or exo thermic. In Unit 3 we examined the different types of solids and their bonds. Take time to understand the properties of each type of solid and bond. We can identify the different species being bonded, so we must be able to determine the type of bonds present in any species. Great work tonight and we will pick up with Unit 3 again on Wednesday."
