A) When a 5.00 g sample of NaOH dissolves in 100.0 g of water in a “coffee cup” calorimeter, the temperature rises from 28.3 degrees C to 39.6 degrees C. Calculate the heat energy for the reaction of 5.00 g of NaOH AND the heat of solution (reaction) for one mole of NaOH dissolving in water.

B) The reaction of hydrochloric acid and sodium hydroxide is exothermic.
The equation is: HCl + NaOH NaCl + H 2O

In one experiment, a student placed 50.0 mL of 1.00 M HCl at 25.5 degrees C on a coffee cup calorimeter. To this was added 50.0 mL of 1.00 M NaOH solution also at 25.5 degrees C. The mixture was stirred and the temperature rose to 37.8 degrees C. What is the heat of reaction in joules per mole of HCL? Assume the specific heat of the solutions is 4.184 J/g degrees C, densities are 1.00 g/mL, and no heat is lost to the cup or to the air.
