The enthalpy change of the precipitation reaction is 84 kJ/mole
Why?
The chemical equation for the reaction is
AgNO₃(aq) + NaCl (aq) → AgCl(s) + NaNO₃(aq)
To find the enthalpy change we need to apply the following equation
To find the heat (Q):
Now, to find the number of moles that react (n):
Having these two values we can plug in the first equation:
