The first P-wave of an earthquake took 11 minutes to travel to a seismic station from the epicenter of the earthquake. What is the seismic station's distance to the epicenter of the earthquake and how long did it take for the first S-wave to travel that distance?
Distance to epicenter: 3350 km/ S-wave travel time: 4 min 50 sec
Distance to epicenter: 3350 km/ S-wave travel time: 6 min 10 sec
Distance to epicenter: 7600 km/ S-wave travel time: 9 min
Distance to epicenter: 7600 km/ S-wave travel time: 20 min

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.
