Hess' Law

New for 2020! ‪@JFRScience‬ 's Mr. Key uses Hess' Law of Heat Summation to determine the overall enthalpy change for a target thermochemical equation using already established thermochemical equations.

Please note that the primary purpose of these videos is educational for students/educators. While all feedback, both positive and...hmmm...constructive, is appreciated I do not have the time to moderate or respond to all comments. As a result, comments on these videos have been disabled at least for the near future.
