Determine the standard enthalpy change for the precipitation reaction between aqueous solutions of silver nitrate (AgNO3) and potassium chloride (KCl), given the molar concentrations of AgNO3 and KCl are 0.10 M and 0.20 M, respectively. The balanced chemical equation for the reaction is:AgNO3(aq) + KCl(aq) -> AgCl(s) + KNO3(aq)The enthalpies of formation for AgNO3(aq), KCl(aq), AgCl(s), and KNO3(aq) are -365.6 kJ/mol, -436.0 kJ/mol, -127.0 kJ/mol, and -494.6 kJ/mol, respectively.
