Abstract: This work is devoted to the construction of homodesmotically reactions of cyclic organic compounds and the determination of the standard enthalpy of formation. A graph-theoretic algorithm ...

A solution was made by dissolving a spatula of potassium nitrate into 50 cm 3 of water. The temperature changed from 20.4˚C to 18.7˚C. Calculate the enthalpy change for this reaction. To calculate the ...

The goal of this study is to use the model system described earlier to make direct measurements of the enthalpy of helix formation at different temperatures. For this we studied model alanine peptides ...

In combustion reactions, some substances will release more energy than others. Enthalpies of combustion can be used to compare which fuels or substances release the most energy when they are burned.
