3. Trial 1: Temperature Change Measure out 50mL of HCl, add to NaOH in calorimeter, wait for a constant temperature reading and then record the change in temperature. 4. Reset Dump out solution in calorimeter and rinse with deionized water. Repeat steps 2 and 3 with more NaOH and HCl for Trial 2 5. Trial 2: Same As Trial One But With More Solution Again, dump out solution in calorimeter and rinse with deionized water. Measure out 50mL of NaOH, pour into calorimeter, record initial temperature. Measure out 50mL of 3M HNO 3 , add to NaOH in calorimeter, record the final temperature. 6. Repeat For Trial 2

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
