Definition of chemical suspension

A chemical suspension is a variety of heterogeneous mixture formed from solid particles that may be powdered or insoluble and that are dispersed in a liquid environment. The particles involved, even the microscopic ones in the solid state, do not dissolve in this framework, which is why they remain […]

Definition of chemical risk

Chemical risk arises every time a chemical substance considered dangerous is handled or present. Uncontrolled exposure to a chemical agent opens the possibility of suffering from multiple pathologies (whether temporarily or permanently), for example. As there are substances capable of generating explosions, fires, diseases and damage […]

Definition of chemical compound

Chemical compound is any substance that arises from combining at least a couple of elements included in the periodic table, which cannot be separated or divided by methods such as distillation, filtration or decantation. If you want to segment the elements involved, you only have to resort to a chemical reaction. There is no […]

Definition of chemical substance

A chemical substance is a variety of matter characterized at the chemical level as precise and homogeneous. The specific feature that characterizes it revolves around its chemical composition, which is fixed. That is, the atoms that make up each of these substances appear only in fixed proportions and the particles that constitute them […]

Definition of reverse sublimation

Reverse sublimation is, according to thermodynamics experts, a process characterized by a phase change experienced by a substance that manages to go from the gaseous state to the solid phase, skipping the liquid state instance. Regressive sublimation, desublimation and deposition are other names given to this phenomenon which, for […]

Definition of pure substance

A pure substance has uniform properties and is characterized by being made up of a single type of particle, whether a molecule or an atom. No matter how much any physical condition of said homogeneous system is altered (temperature, pressure, etc.), its chemical composition remains stable and well defined. So, then, its chemical structure does not […]

Definition of analytical method

The analytical method is a type of scientific research based on empirical reasoning and experimentation. This is a model used by empirical sciences, both natural and social. It can be indicated that the analytical method is a work methodology used by scientists. Its purpose is the production of knowledge […]

Definition of chemical industry

The chemical industry is essential to, with chemical resources and procedures, transform multiple raw materials into different items that are useful in various contexts. By contributing to various industries by providing inputs made from mineral and/or animal sources and processing chemical components, it is an area of ​​enormous relevance within the […]

Definition of glycolysis

Glycolysis is a term that is also accepted by the Royal Spanish Academy (RAE) as glycolysis (with an accent on the first I). Glycolysis and glycolysis, in turn, are synonyms for glycolysis and glycolysis. All these ideas are used in the field of biochemistry to refer to the series of reactions that occur […]

Definition of Calvin cycle

The Greek word kýklos, which can be translated as "circle", derived from the Latin cyclus. This is the closest etymological antecedent of cycle, a term that has several uses. The succession of phases that a periodic phenomenon goes through is called a cycle; to the time span that covers various characteristic events: to the stage […]
