Hess's Law:
Calculate Î”H for the neutralizationof HCl_(aq) byNaOH_(s). I'M NOTSURE WHAT DATA YOU NEED, SO I COPY AND PASTED ALL OF MYDATA.
A. Î”H_solution of NaOH_(s) PhaseChange:
Mass of NaOH: 2.05 g
Î”T for reaction A : 8.0 Â°C

B. Î”H_solution for neutralization ofHCl_(aq) and NaOH_(aq):
Volume of HCl: 0.0500 L
Volume of NaOH: 0.0500 L
Volume total: 0.100 L
Molarity of HCl: 1.95 M
Molarity of NaOH: 1.95 M
Î”T for reaction B: 11.0Â°C

C. Î”H for Reaction of HCl_(aq) andNaOH_(s):
Volume of HCl: 0.0550 L
Volume of water: 0.0450 L
Volume total: 0.100 L
Molarity of HCl: 1.95 M
Mass of NaOH: 3.44 g
Î”T for reaction C: 17Â°C

D. Î”H for Solution of KCl_(s) inwater:
Î”T for reaction D: -5.0Â°C
Mass of KCl: 5.02 g
Volume of water: 0.0500 L
