Homework Help: chemistry

Posted by Daniel on Monday, January 17, 2011 at 3:16pm.

three student chemists measured 50.0 mL of 1.00 M NaOH in separate Styrofoam "coffee cup" calorimeters ( Part B). Brett added 50.0 mL of 1.10 M HCI to his solution of NaOH; Dale added 45.5 mL of 1.10 m HCL 9 eqaul moles) to his NaOH solution. Lyndsay added 50.0 mL of 1.00 m HCI to her NaOH solution. Each student recorded the temperature change and calculated the enthalpy of neutralization.
Two of the chemists will report, within experimental error, the same temperature change for the HCL/NaOH reaction. Identify the two students and explain.
