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.

HESS'S LAW, BIG MAMA, HEAT OF FORMATION, BOND ENERGY TEST WITH SOLUTIONS

This chapter will teach you how to: -understand the term enthalpy change and apply it to exothermic and endothermic chemical reaction. -construct a reaction pathway in terms of enthalpy changes and activation energy. -define the term standard conditions. - know about the variety of enthalpy changes such enthalpy change of formation, combustion, reaction and neutralisation. -use bon energies to calculate enthalpy change of reaction.

Elevate your knowledge with our in-depth notes on Thermodynamics and Thermal Chemistry! Dive into essential concepts like Entropy, Enthalpy, Spontaneity, Thermodynamic laws, Gibbs Free Energy and so much more . Perfect for students and professionals, our notes simplify complex theories, and enhance your grasp of energy transformations and reactions.

This document is very easy to understand. And are very well summarised so that everyone should able to understand this.
