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)

A student wants to determine the polarization in an electrochemical cell where the anode is made of zinc and the cathode is made of copper. The electrolyte used is CuSO4. The current through the cell is 0.5 A and the measured potential difference is 1.5 V. What is the polarization of this electrochemical cell?
