Hess' Law

This page is an exercise in using Hess' Law. When you press "New Problem" a window will appear which presents a Hess' Law scenario. If the new window covers up any of the needed parts of this main window, the new window can be dragged to a new position. Calculate the needed enthalpy, enter it in the cell and press the "Check Answer" button. The results will appear in the table on the main page. This page is complex, but it's not intended to be tricky. Thus, no attempt has been made to mislead you. There should be a straightforward combination of the contributing reactions which yields the desired reaction.
