Calculate the standard enthalpy change for the precipitation reaction: AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)given that the standard enthalpy of formation for AgCl(s) is -127.0 kJ/mol, and for NaNO3(aq) is -467.14 kJ/mol. The molar enthalpy of solution of NaCl and AgNO3 are -3.9 kJ/mol and -19.9 kJ/mol respectively.
