Energy is like the bestest best friend ever and yet, most of the time we take it for granted. Hank feels bad for our friend and wants us to learn more about it so that we can understand what it's trying to tell us - like that any bond between two atoms contains energy. How much energy? That's not the simplest question to answer, but today Hank will answer it (kinda), by teaching us about a nifty little thing called enthalpy.
If you are paying attention to this episode you'll learn what the state function is, and how it varies from a path-dependent function; why enthalpy change is different from heat; that bonds are energy and to form and break them they release and absorb heat to and from their environment. You'll get the quickest introduction to calorimetry ever (more on that in upcoming episodes) and learn the power of Hess's Law and how to use Germain Hess's concept of the standard enthalpy of formation to calculate exactly how much heat is produced by any chemical reaction.
So much to learn! Let's get started!

053 - Enthalpy of Reaction
In this video Paul Andersen explains how the enthalpy of a reaction can be released in an exothermic or consumed in an endothermic reaction. According to Hess's law if the reaction is reversed the sign of the enthalpy of reaction is also reversed. The overall enthalpy of reaction is the sum of all the individual reactions. A couple of enthalpy of reaction problems are worked out as well.

Energy is the ability to move change or change matter. If energy is released during a chemical reaction it is an exothermic reaction and the products have less energy than the reactants. If energy is absorbed during a chemical reaction it is an endothermic reaction and the products have more energy than the reactants.
Enthalpy is the measure of the energy content.
Entropy is the increasing of disorder.

Enthalpy is a measure of the total energy of a thermodynamic system. It includes the internal energy, which is the energy required to create a system, and the amount of energy required to make room for it by displacing its environment and establishing its volume and pressure.
Enthalpy is a thermodynamic potential. It is a state function and an extensive quantity. The unit of measurement for enthalpy in the International System of Units (SI) is the joule, but other historical, conventional units are still in use, such as the British thermal unit and the calorie.
The enthalpy is the preferred expression of system energy changes in many chemical, biological, and physical measurements, because it simplifies certain descriptions of energy transfer. This is because a change in enthalpy takes account of energy transferred to the environment through the expansion of the system under study.
The total enthalpy, H, of a system cannot be measured directly. Thus, change in enthalpy, ΔH, is a more useful quantity than its absolute value. The change ΔH is positive in endothermic reactions, and negative in heat-releasing exothermic processes. ΔH of a system is equal to the sum of non-mechanical work done on it and the heat supplied to it.

053 - Enthalpy of Reaction
In this video Paul Andersen explains how the enthalpy of a reaction can be released in an exothermic or consumed in an endothermic reaction. According to Hess's law if the reaction is reversed the sign of the enthalpy of reaction is also reversed. The overall enthalpy of reaction is the sum of all the individual reactions. A couple of enthalpy of reaction problems are worked out as well.

Energy is the ability to move change or change matter. If energy is released during a chemical reaction it is an exothermic reaction and the products have less energy than the reactants. If energy is absorbed during a chemical reaction it is an endothermic reaction and the products have more energy than the reactants.
Enthalpy is the measure of the energy content.
Entropy is the increasing of disorder.
