Assuming that the specific heat of the solution is 4.18 KJ and that the calorimeter itself absorbs a negligible amount of heat, calculate delta H in kilojoules for the reaction K2O+H2O->2KOH. When 1.045 g of K2O is added to 50.0 mL of water at 25.0 C in a calorimeter, the temperature of the water increases to 41.5 C.
When a substance is heated it glows and emits a certain amount of radiant energy that corresponds to particular energies in the electromagnetic spectrum.
What is the specific heat of liquid water, written with correct units? Refer to Table 5.2 or Appendix B in your textbook, or your lecture notes.
