Calculate for the solubility of CaCO3 in water that is also in equilibrium with atmospheric CO2, but this time for a water temperature of 5 ⁰C. At this temperature, KH = 0.065 for CO2 and Ka1 for H2CO3 is 3.0x10-7. Ksp for CaCO3 = 8.1x10-9, Ka2 = 2.8x10-11 for HCO3-, and Kw=0.2x10-14.

Assume everyone in this Econ of Ed class decided to pursue a PhD in Economics after seeing how fun research in Econ of Ed can be. The present value economic cost of attending the PhD in Economics is $162,000 (although tuition is typically zero and students are paid a stipend, PhD students incur non-pecuniary costs associated with the stress of being in a demanding program, in addition to lost wages while in school). A quant GRE score is an application requirement for admission to a PhD in Economics. Each student in the class takes the GRE and they receive scores uniformly distributed from 130 to 170 on the quant section. Present value future utility (including both pecuniary and non-pecuniary aspects) are a function of GRE scores for both PhD graduates and non- graduates, as the GRE score measures on-the-job productivity AND is related to non-pecuniary benefits of working. Present value payoffs are Y BA =200*GRE for people who choose not to pursue the PhD, while those that choose the PhD earn YPhD =2000 + 1200*GRE. a. What is the minimum GRE score of the students who choose to get the PhD? b. What is the average payoff of each group? (Those who do and do not get the PhD?) c. What payoff would the person with the average GRE score have with and without the PhD?
