Chemistry

Hess's Law:
Calculate ΔH for the neutralizationof HCl(aq) byNaOH(s). I'M NOTSURE WHAT DATA YOU NEED, SO I COPY AND PASTED ALL OF MYDATA.

A. ΔHsolution of NaOH(s) PhaseChange:
Mass of NaOH: 2.05 g
ΔT for reaction A : 8.0 °C

B. ΔHsolution 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
ΔT for reaction B: 11.0°C

C. ΔH 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
ΔT for reaction C: 17°C

D. ΔH for Solution of KCl(s) inwater:
ΔT for reaction D: -5.0°C
Mass of KCl: 5.02 g
Volume of water: 0.0500 L
