Calculate the heat of reaction if 50.0 milliliters of 0.500 M HNO3 is mixed with 50.0 milliliters of 0.500 M Ca(OH)2 in a coffee cup calorimeter with
a heat capacity of 22.5 J/K. Prior to mixing both solutions were at 23.4 C. After mixing, the final temperature of the calorimeter system was 40.4 C.
Assume the heat capacity of the combined solution mixture is 4.184 J/g K.

In one of the General Chemistry experiments, you used a coffee-cup calorimeter to measure the heat of neutralization of selected acid-base reactions. The calorimeter consisted of two nested Styrofoam cups with a cardboard lid. A temperature probe was lowered in the solution through a hole in the lid. Is a coffee-cup calorimeter a constant-volume or a constant-pressure device? Is a coffee-cup calorimeter adiabatic? The coffee-cup calorimeter was calibrated by using the neutralization reaction between sodium hydroxide and hydrochloric acid. The...
