Lab 9: Enthalpy of Formation of Ammonium Salts Flashcard

__________ __________ states that the enthalpy change of individual steps in a process can be added or subtracted to determine the overall enthalpy change of the process.
1) Hess’s Law
The __________ __________ __________ __________ states that the enthalpy change of a reaction be the same regardless of the reaction pathway that leads from reactants to products.
1) First Law of Thermodynamics
qreactions = __________
1) -qwater
The heat exchanged in a reaction can be determined by the reaction:
q = __________ x __________ x __________
1) q = c x m x delta T, where:
q = heat
c = The specific heat of a substance
delta T = Is the temperature change.
