Summary AP Classroom for Chemical Thermodynamics Test | 2023. The reaction between SO2 and O2 is represented by the chemical equation above. The table provides the approximate absolute entropies, S°, for O2(g) and SO3(g). Which of the following mathematical expressions can be used to correctly calculate S° for SO2(g) ? C. S°=12[187+(2×257)−205]J/(mol⋅K) Since ΔS°reaction=Σ(moles of substance×S°)products−Σ(moles of substance×S°)reactants, if x=S° for SO2(g), then −187=...

1. Combining independent probabilities. You have applied to three medical schools: University of California at San Francisco (UCSF), Duluth School of Mines (DSM), and Harvard (H). You guess that the probabilities you’ll be accepted are: p(UCSF) = 0.10, p(DSM) = 0.30, and p(H) = 0.50. Assume that the acceptance events are independent. (a) What is the probability that you get in somewhere (at least one acceptance)? (b) What is the probability that you will be accepted by both Harvard and D...
