Barium hydroxide will dissolve in an aqueous solution of ammonia and drive off ammonia gas according to the following reaction: Ba(OH)2(s)+2NH4+(aq)Ba2+(aq)+2H2O(I)+2NH3(g) The standard enthalpies of formation for each of the species involved are: Ba(OH)2(s)[944.7kJ/mol];NH4+(aq)[132.5kJ/mol];Ba2+(aq)[537.6kJ/mol];H2O(I)[285.8kJ/mol];NH3(g)[46.11kJ/mol]. What is the standard enthalpy of reaction for the barium hydroxide solvation process as written above? 207.7kJ/mol 207.7kJ/mol 1201.4kJ/mol 8.3kJ/mol 1881.1kJ/mol 8.3kJ/mol
