Calculate the standard enthalpy change (in kJ/mol) for the reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH) to form sodium chloride (NaCl) and water (H2O), given the following balanced chemical equation:HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (l)Assume the reaction takes place under standard conditions (298 K and 1 atm pressure) and that all solutions have a concentration of 1.0 M. The standard enthalpies of formation for HCl (aq), NaOH (aq), NaCl (aq), and H2O (l) are -92.31 kJ/mol, -469.14 kJ/mol, -407.76 kJ/mol, and -285.83 kJ/mol, respectively.

A chemistry student is given the following information: A galvanic cell is set up consisting of a copper electrode in a copper (II) ion solution connected by a salt bridge to a silver electrode in a silver ion solution. The concentration of the copper (II) solution is 0.10 M and the concentration of the silver ion solution is 0.025 M. The measured potential of the cell is 0.66 V. Calculate the resistance of this electrochemical cell.
