Three student chemists calculated 50.0 mL of 1.00 M NaOH in separate styrofoam cups calorimeters. Brett added 50.0 mL of 1.10 M HCl to his solution of NaO; Dale added 45.5 mL of 1.10 M HCl equal moles to his NaOH solution. Lyndsay added 50.0 mL of 1.00 M HCl to her NaOH solution. Every student recorded the temperature change and computed the enthalpy of neutralization. Classify the student who observes a temperature change that will be different from that observed by the other two chemists. Explain why is the temperature different?
