QUE SIGNIFIE CHEMICALS EN ANGLAIS

Substance chimique

Chemical substance

En chimie, une substance chimique est une forme de matière qui a une composition chimique constante et des propriétés caractéristiques. Il ne peut pas être séparé en composants par des procédés de séparation physique, c'est-à-dire sans rupture de liaisons chimiques. Il peut être solide, liquide, gazeux ou plasma. Les substances chimiques sont souvent appelées «pur» pour les séparer des mélanges. Un exemple commun d'une substance chimique est l'eau pure; Il a les mêmes propriétés et le même rapport d'hydrogène à l'oxygène, qu'il soit isolé d'une rivière ou fabriqué en laboratoire. D'autres substances chimiques généralement rencontrées sous forme pure sont le diamant, l'or, le sel de table et le sucre raffiné. Cependant, des substances simples ou apparemment pures trouvées dans la nature peuvent en fait être des mélanges de substances chimiques. Par exemple, l'eau du robinet peut contenir de petites quantités de chlorure de sodium dissous et des composés contenant du fer, du calcium et de nombreuses autres substances chimiques. Les substances chimiques existent sous forme de solides, liquides, gaz ou plasma et peuvent changer entre ces phases de la matière avec des changements de température ou de pression. Les réactions chimiques convertissent une substance chimique en une autre.

In chemistry, a chemical substance is a form of matter that has constant chemical composition and characteristic properties. It cannot be separated into components by physical separation methods, i.e. without breaking chemical bonds. It can be solid, liquid, gas, or plasma. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond, gold, table salt and refined sugar. However, simple or seemingly pure substances found in nature can in fact be mixtures of chemical substances. For example, tap water may contain small amounts of dissolved sodium chloride and compounds containing iron, calcium and many other chemical substances. Chemical substances exist as solids, liquids, gases, or plasma and may change between these phases of matter with changes in temperature or pressure. Chemical reactions convert one chemical substance into another.

Lack of scientific fundamentals causes people to make foolish decisions about issues such as the toxicity of chemicals, the efficacy of medicines, the changes in the global climate.
