This is an exam I did in class and this one has been revised, if you find anything wrong with it please let me know. My teacher was very nice but also wanted us to know most things so this is a more challenging exam than most, so it should be similar to the others out there, if you can do this then you can also do any other exam about this chapter of chemistry.

This document just had a lot of important notes, important definitions, and lots of examples, and everything is clean and well-made in order to keep everything from being confusing as long as you understand everything up until this point. There are some explanations but this is from the point of view of an average person that just happened to get an A in the class and pass the final for General Chemistry 1 with a %90.

The PDF explains Hess's Law, which states that the total enthalpy change of a chemical reaction is independent of the reaction pathway as long as the initial and final conditions are the same. It introduces Hess cycles, illustrating how to use them to calculate enthalpy changes that cannot be determined experimentally. The document includes worked examples, such as calculating enthalpy changes and bond energies using energy cycles, providing step-by-step guides for solving these problems. It ...
