The video discusses the concept of enthalpy of linkage, or energy of linkage. This is the amount of energy released when a chemical linkage is formed. The enthalpy of linkage is defined as the energy released when atoms form bonds to create molecules. The colder the environment, the greater the energy released in the reaction of formation of links.

• 00:00:00 The video discusses the concept of enthalpy of linkage, or energy of linkage. When a chemical linkage is formed, a certain amount of energy is released. This energy is the same energy that we must provide to break the linkage later. We can define the concept of enthalpy of linkage as the energy that is released or the variation of energy experienced when linkage is formed from free atoms and a gas state, for example. If we consider a concrete example with molecules of free and gaseous elements, we have molecules of free and gaseous element forming a molecule of atomic hydrogen, for example. In this reaction, a energy of 242 kilojoules is released. Cloud or cloud, which is more commonly known, refers to the energy released in a delayed manner that we'll call enthalpy of day. It is typically negative, which indicates that energy is being released. When linkage is formed, free atoms and gas molecules will form bonds. These bonds will break and release energy. The colder the environment, the greater the energy released in the reaction of formation of links. For example, when we form a mold of molecules of chlorine from free atoms of chlorine and atomic hydrogen, we'll have a value of 242 kilojoules and jou
• 00:05:00 In this video, thermodynamics theory 12, the concept of energy of linkage or linkage energy is explained. There are different simple links, covalent links, of which we can give their value, for example, we will consider a series of links here on the board, which are the following: H2O: this is less than 436 We usually put the negative signs next to the fact that, when a mold is formed, the cation separates energy, but also you can find tables with a positive value that is not important what we need to know is that the absolute value will be negative if we consider the information reaction reaction and positive values that consider the reaction of dissociation as can be seen from the two ways, sometimes it is negative and sometimes it is positive. I will put it negative but we must be aware that it can also be found in the form of the opposite in my case of chlorine, we will have an energy of linkage of less 242 and the Julios divided into parts also we can have the case of the link bromine-bromine with a value of less 193, so this is a weaker link than we two, and also we can consider the link carbon-carbon which has a
