Using the following thermochemical data, what is the change in enthalpy for the following reaction?
Ca(OH)¿(aq) + HCl(aq) d CaCl¿(aq) + H¿O(l)
CaO(s) + 2HCl(aq) d CaCl¿(aq) + H¿O(l), DH = -186 kJ
CaO(s) + H¿O(l) d Ca(OH)¿(s), DH = -65.1 kJ
Ca(OH)¿(aq) + HCl(aq) d CaCl¿(aq) + H¿O(l)
CaO(s) + 2HCl(aq) d CaCl¿(aq) + H¿O(l), DH = -186 kJ
CaO(s) + H¿O(l) d Ca(OH)¿(s), DH = -65.1 kJ
