AB Pre-exam 2 checklist. Theses are a few topics (not exclusive) that we should be comfortable with for the next lecture. They have been taken directly from the published lecture notes. They fall roughly into two classes: conceptual and definitional issues, and calculation skills. This list is not offered as something too be memorized but as a hopeful aid in focusing our studies. stoichiometry calculations . Ex: How many mL of pentane are needed to make 20 mL of a one molar solution in dichloromethane solvent. The density of pentane at 25 is 0.626 g/mL. There are many many more examples. Balancing equations Ex: Balance AgNO 3 + MnCl 2 => AgCl + Mn(NO 3 ) 2 . Ex: Potassium permanganate (KMnO 4 ) reacts with sodium bromide in water to form molecular bromine and manganese dioxide. Balance the equation for this oxidation reaction. Exothermic, endothermic, thermoneutral Ex: Which give off heat? Which have K eq > 1? Which proceed to a lower energy? Which have Δ Hº > 0?
