Here the questions for the link in video

A. BOMB CALORIMETRY VIDEO

a. Why should the water jacket of the calorimeter be reflective?
b. Why is benzoic acid used to calibrate a bomb calorimeter?
c. Why should the fuse wire not touch the crucible cup?
d. Why do you need to purge the nitrogen out of the bomb calorimeter?
e. How can you know if the combustion of your sample is complete?
f. How would you prepare liquid samples for bomb calorimetry?

Here the questions for simulatation
B. SIMULATION

Plot of No. of Carbon Atoms (x-axis) Vs │| ∆H│ (in kJ/mol) (y-axis)
Equation of the Line:
Correlation coefficient r =
Interpretation:

POST-LAB QUESTIONS
1. Write the balanced chemical equation for the combustion of solid benzoic acid performed in
the simulation. Is the ΔH greater than, less than, or equal to the ΔE for this process?
2. Why is a bomb calorimeter immersed in water?
3. Why is the fuel value an important property in comparing different fuels?
