Calorimetry calculations often assume no heat exchange

Calorimetry calculations often assume no heat exchange between the calorimeter and the surroundings, but in real life this heat transfer does in fact occur. Correctly complete the following statements regarding the results of actual calorimetry experiments. Zinc reacts with hydrochloric acid in a coffee cup calorimeter and the temperature of the solution increases by 32.3°C. In this experiment, heat flows and the experimentally determined enthalpy change will be -- enthalpy change for the reaction. Citric acid reacts with sodium bicarbonate in a coffee cup calorimeter and the temperature of the solution decreases by 18.7°C. In this experiment, heat flows -- the calorimeter, the measured temperature change is temperature change that would occur in a perfectly insulated calorimeter, and the experimentally determined enthalpy change will be --
