Summary
Chemical changes occur around us, and inside us, all the time. When chemical reactions happen, one or more new substances are formed and energy is either given off or absorbed in the process. Spontaneous chemical reactions, those that occur naturally under favorable conditions release free energy, meaning they are exergonic. Endergonic reactions, by contrast, require net energy input to make the reaction happen. This resource explores energy associated with chemical reactions, and cover areas such as activation energy and product formation, standard heats of reaction, thermochemical equations and Hess' Law, and specific heat capacity and calorimetry. It is essential viewing for any Chemistry student, providing clear explanations and easily understood visuals, including comprehensive chemical equations, about concepts that many students find challenging.

Summary
Many chemical reactions involve explosions, bubbling gases, flames, and smoke because energy is being transferred from one form to another-the realm of thermodynamics. Thermodynamics, the rules for predicting the progress of a reaction and harnessing the energy released, is key to solving engineering problems, such as making cleaner and more efficient automobile engines.

Summary
Stoichiometry helps chemists find the relative amounts of reactants and products in chemical reactions. Balancing the number of atoms on each side of the equation, calculating the amount of each reactant, and figuring out which reactant will run out first are all fundamental principles when designing any chemical reaction. These principles are applied when splitting water into hydrogen and oxygen for energy, manufacturing sodium iodide for radiation detectors, and producing common chemicals from renewable resources.
