Definition of hydrolysis

Hydrolysis is a phenomenon that occurs when the division of a water molecule develops with the consequent breaking of one or more chemical bonds and the union of its atoms to the other substance that intervenes and decomposes. This type of chemical reaction is very common since water usually […]

Definition of lithium

Lithium is the name given to a chemical element that, within the periodic table, is located in group 1 accompanied by other alkaline metals, such as francium, potassium, cesium, sodium and rubidium. This metal, which is characterized by being very reactive, is recognized as […]

Definition of law of conservation of energy

The law of conservation of energy is the first of the principles that govern thermodynamics. It is also contemplated within the fields of analytical mechanics and chemistry (in the latter case, when analyzing the characteristics of a chemical reaction it is confirmed that there is a conservation of mass […]

Definition of chemical bond

Chemical bond is the expression that identifies a force by which atoms can be held together in a stable system. Thanks to chemical bonds, the theory says, molecules and other elements are assembled, just as a chemical compound can achieve stability. When a mole of bonds is formed based on a set […]

Definition of acetic acid

Acetic acid is a chemical compound made up of carbon, hydrogen and oxygen. It is an organic substance that is also called ethanoic acid or methylcarboxylic acid. This liquid, which lacks color and is characterized by its pungent odor, is generated when ethyl alcohol or ethanol oxidizes. It can be obtained […]

Definition of carbon cycle

The carbon cycle is the cyclic process that this chemical element develops as it circulates through the atmosphere, the hydrosphere, the geosphere and the biosphere. This series of events is indispensable for life to exist on planet Earth. It should be noted that the carbon cycle is a biogeochemical cycle, just like […]

Definition of sulfuric acid

Sulfuric acid is the name that identifies a chemical compound that arises from sulfur dioxide (SO2). This resource, with a chemical formula (H2SO4), is used to synthesize various materials and has multiple applications at an industrial level. It should be noted that sulfur dioxide (SO2) is essential to manufacture sulfuric acid. At the time […]

Definition of fossil fuel

A fossil fuel is a natural source of energy that arises when organic matter decomposes and goes through a process that spans millions of years. The slowness with which this transformation is carried out means that these fuels are not renewable since they are consumed much faster than […]

Definition of Dalton's atomic model

Dalton's atomic model is a presentation that, between 1803 and 1807 (or 1808, depending on the source consulted), was made by the British scientist John Dalton. For this expert, the proposal that has remained in history as the first of the atomic models that had scientific support, was an atomic theory. […]

Definition of biogeochemical cycle

A biogeochemical cycle is a set of processes carried out with the intervention of living beings and abiotic factors that makes the circulation of energy through the biosphere possible. These cyclical journeys allow the transformation and transfer of elements that are essential for life to exist. It is important to indicate that the […]
