The Thermochemical Equation

This page provides exercises in the use of thermochemical equations. To produce a problem, click on the "New Problem" button and a question will appear. Determine the value of the answer, enter it in the cell and press "Check Answer". Be careful about the sign of the heat change. All heats should be entered in terms of kJ. Since this page is designed to provide exercises in using theormochemical equations, the heats are randomly generated and should not be considered as accurate for the described processes If you miss a problem three times, pressing "Show Answer" will cause the correct answer to appear.
