100.0 mL of 2.000 M sodium hydroxide is mixed with 200.0 mL of 1.000 M nitric acid.
Both solutions are initially at a temperature of 23.00 °C, the resulting sodium nitrate
solution has a temperature of 31.91 °C
What is the heat of neutralization (H) for this reaction?
[Assume that the density and heat capacity of all solutions are identical to that of water:
1.000 g/mL and 1.000 cal/g°C and that there is no loss of heat from the solution.]
