Calculate the standard enthalpy change for the precipitation reaction: AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq) Given that the standard enthalpy of formation (∆Hf) for AgNO3(aq), NaCl(aq), AgCl(s), and NaNO3(aq) are -123.1 kJ/mol, -407.3 kJ/mol, -127.0 kJ/mol, and -467.3 kJ/mol respectively.

Calculate the enthalpy change for the dissolution of 5.00 g of sodium hydroxide (NaOH) in 100.0 g of water (H2O). The temperature change was measured to be -3.45°C. Given that the specific heat of water is 4.18 J/g°C and the density of water is 1.00 g/mL. (Assume that the heat evolved from NaOH is absorbed by the water.)
