Calculate the standard enthalpy change for the precipitation reaction of solid silver chloride (AgCl) from the aqueous solution with the precipitation agent, hydrochloric acid (HCl). Given the molar enthalpies of formation of AgCl(s) and HCl(g) are -127.01 kJ/mol and -92.31 kJ/mol, respectively. The balanced equation for the reaction is: AgNO3(aq) + HCl(aq) → AgCl(s) + HNO3(aq)

Calculate the enthalpy of polymerization of ethylene from the following data: Ethylene, C2H4(g) polymerizes to form polyethylene, (C2H4)n(s) with ΔHrxn = -44.0 kJ/mol at 298 K. Additionally, it is known that the standard enthalpies of formation of C2H4(g) and polyethylene (C2H4)n(s) are 52.3 kJ/mol and -128.2 kJ/mol, respectively. Assuming the enthalpy of polymerization is independent of temperature, calculate ΔHºp for the reaction.
