Has anyone here done an experiment where you add MgO to HCl in a calorimeter or coffee cup calorimeter? If you have, did you have to record the temperature every 30 seconds or minute? If you did, do you know how much the temperature should go down every minute? Because I did it and it only went down like 0.1 seconds every minute. Is that too little?
What did you get for heat of reaction?

For the reaction:
MgO + 2 HCl --> MgCl2 + H2O
The temperature should go up, not down. Only the initial and final temperature are needed.
Typical values for students are between 110 an 150 kJ/mol MgO. This is typical, not the best that can be done.
