Acetic acid when pure, has a freezing point of 16.0 Celsius; Liquid acetic acid has a heat capacity of 1.96J/g*C. A 25.0 g piece of solid acetic acid at 16.0C is placed into an insulated container containing 50.0g of liquid acetic acid at 50.0C. when the temperature of the mixture reached 16.0C there is 7.7g of solid acetic acid left. a) calculate delta rxn H degrees for CH3CO2H(s) --> CH3CO2H(l) b)what is the term for this specific enthalpy change Please SHOW ALL steps, and make writing very Clear.
