Practice Problem: Hess's Law

If we want to find out some information regarding the enthalpy change of a reaction, but we don't want to perform the reaction, we can use Hess's law, which allows us to manipulate thermochemical data for related reactions. Let's practice this technique!

    What's enthalpy? I don't understand ANY of this but I get a great sense of satisfaction knowing that someone out there does 👊😁👍

    Enthalpy is the sum of internal energy and pressure volume work done. It is equivalent to the total heat supplied to the system.

    It's been years since I've practiced any kind of engineering, and even longer since I've been in school, but this is still fun to listen to. (I'm also enjoying the Italian lessons) Thanks, Professor Dave! ❤️

    What if the given thermochemical equations have the same compound with what you're looking for, for example, for F2 then the given equations have F2, what equation to choose?
