Experiment 7: Calorimetry – Lab Notebook Prep
Note: Prepare your lab notebook with these tables, but you will not be submitting these pages from your
lab manual. Instead, you will submit a formal lab report which includes the data and results in
these tables.

For each trial, attach the Data Table obtained using the Vernier LabQuest system, along with the titled graph
with labeled axes that shows the regression line and the y-intercept with the maximum temperature (Tfinal).
Show calculations for each step of the HCl(aq)-NaOH(aq) and the HNO3(aq)-NaOH(aq) neutralization
reactions in your lab notebook.
