Consider the dissolution of CaCI2: CaCl2(s) Ca (aq) + 2CI (aq) AH = -81.5 kJ/mol A 15.0-g sample of CaCl, is dissolved in 135 g water with both substances at 25.0°C. Calculate the final temperature (in °C) of the solution assuming no heat loss to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C g.

From the surreal realm of deep-seahydrothermal vents 200 miles offshore from Puget Sound, comesa newly discovered hyperthermophilic—or extreme heat-loving—microbe that holds the record for the hottest existence known toscience. This microbe is tentatively known as Strain 121 for thetemperature at which it thrives: 121 °C. (At sea level, water at thistemperature would boil vigorously, but the extreme pressures atthe ocean floor prevent boiling from occurring.) What is this temperature in degrees Fahrenheit?
