Question 8 ( 1 point) Magnesium hydroxide will dissolve in an aqueous solution of ammonia and drive off ammonia gas according to the following reaction: Mg(OH)2(s)+2NH4+(aq)Mg2+(aq)+2H2O(l)+2NH3(g) The standard enthalpies of formation for each of the species involved are: Mg(OH)2(s)[924.5kJ/mol;NH4+(aq)[132.5kJ/mol];Mg2+(aq)[466.9kJ/mol];H2O(l)[285.8kJ/mol];NH3(g)[46.11kJ/mol]. What is the standard enthalpy of reaction for the magnesium hydroxide solvation process as written above? 294.1kJ/mol+58.8kJ/mol408.1kJ/mol58.8kJ/mol258.2kJ/mol+258.2kJ/mol At 25C, the equilibrium vapour pressure of ethanol is 0.0899bar. The standard enthalpy of vapourization is 37.33kJ/mol. What is the boiling point of ethanol at standard pressure? In other words, at what temperature does the equilibrium vapour pressure of ethanol reach 1.000 bar? Report your answer in degrees Celsius, but do Your Answer: Your Answer At 25C, the equilibrium vapour pressure of ethanol is 0.0899bar. The standard enthalpy of vapourization is 37.33kJ/mol.
