A scientist measures the standard enthalpy change for the following reaction to be -19.2 kJ: Ca(OH)2 (aq) + 2HCl(aq) → CaCl₂ (s) + 2H₂O(1) Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of HCl(aq) is kJ/mol. Species AH (kJ/mol) CaCl₂ (8) H₂O(l) Ca(OH)2 (aq) -795.8 -285.8 -1002.8
