Calculate the enthalpy change, ∆Hrxn, for each sub-reaction in terms of kJ/mol. Remember that the sign of q from the calorimeter represents the surroundings (+) and q from the reaction represents the system (−).

according to kinetic-molecular theory, the following would not be considered an ideal gas:

a gas at very low volumes, when gas particles are very close together

a gas at very low temperatures, when gas particles have very little kinetic energy a gas

a gas with highly polar molecules that have very strong intermolecular forces

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
