Hess's Law - Questions

The Hess's Law Concept Builder provides learners an opportunity to apply Hess's Law in order to determine the enthalpy change of a reaction. The ∆H of two or three reactions is given. Their equations must be manipulated (reversed, multiply coefficients by a factor, etc.) and added to provide the target equation. Once accomplished, their ∆H values must be used to determine the ∆H for the target reaction. The Concept Builder consists of 27 questions organized into 9 Question Groups and spread across three difficulty levels.Question-specific help is provided for each of the 9 Question Groups. The built-in feedback makes this Concept Builder a perfect candidate for student practice or a classroom activity. And the use of the activity with our Task Tracker program allows teachers to view records of student progress.
