Question

Enthalpy of Reaction 2 (ΔH2) in kJ/mol of NaOH

Be careful! Make sure your energy is in units of kJ, not J.

1. Mass of NlaOH (g)
25.00
Initial temperature
2.
(*C)
37.14
3.
Final temperature ('C)
this is reaction 2
Calculations

Change in temperature of the reaction
solution, ATin ('C)
Part 3 of 6
Mass of the reaction solution, mln (8)
Add together the masses of the NaOH(s),
water, and HCI(aq). Convert the volumes
of water and HC(aq) to mass using 1.000
g/ml as the density (we are assuming the
HCI solution has the same density as
water, see procedure for volumes used).
