The chemical equation for the dissolution of lithium chloride (Licl) is Licl (s)

Question

The chemical equation for the dissolution of lithium chloride (Licl) is Licl (s) -----------H2li+ (aq) + cl (aq) the delta H solution value for this process is 37.4kj/mole . Part A Question Select the Delta H values associated with the dissolution of lithium chloride that are exothermic. Check all that apply. (A) Delta H1= energy associated with the separation of water molecules (B) Delta H2:= energy associated with the separation of Licl ions (C) Delta H3= energy associated with the formation of water ion interaction (C) Delta Hsolution= the enthalpy of solution Part B Question Predict what must happen when a beaker containning a solution of lithium chloride is heated check all that apply (a) the reaction will become endothelmic (b) energy will be transfered into the system (c) Delta H3 values will increase (d) Delta Hsolution values will decease

Explanation / Answer

energy associated with the formation of water-ion interactions the enthalpy of solution
