In a calorimetry experiment similar to the one performed today, a student used 50.0 mL of 1.0 M NaOH and 50.0 mL of 1.0 M HCl each initially at 22.5 °C. The maximum temperature observed after mixing was 28.0 °C. What is the heat of reaction in units of kJ?

Expert Solution
Step 1
Since you have posted multiple questions, we are entitled to answer the first only.
5) Given: Concentration of NaOH = 1.0 M
Concentration of HCl = 1.0 M
Volume of NaOH solution = 50.0 mL.
Volume of HCl solution = 50.0 mL.
Initial temperature of the solution = 22.5 oC
And the final temperature of the solution = 28.0 oC
