A perfect calorimeter would not allow heat loss to the surroundings.


The enthalpy of reaction for Mg and MgO with HCl is needed to calculate the enthalpy of formation of MgO.


The measurement of temperature, mass, volume are all sources of error for this experiment.


The Cp is needed to determine the change in temperature for each trial.


The enthalpy of reaction and enthalpy of formation for MgO are the same thing.
