Practice Final Exam for C125
There are 60 questions in final exam. This practice exam should not be your primary tool
for your study because it contains very limited number of questions. It is a better tool to
evaluate your study when you are relatively p

In the thermochemistry and calorimetry lab, students are focused on finding what
the numerical value of the heat of reaction. Once that is found, the value can be applied
to other problems to further what is known about the change in energy. In doing so,
