  2. Chemically inert - Wikipedia

    en.wikipedia.org/wiki/Chemically_inert

    In chemistry, the term chemically inert is used to describe a substance that is not chemically reactive. From a thermodynamic perspective, a substance is inert, or nonlabile , if it is thermodynamically unstable (positive standard Gibbs free energy of formation ) yet decomposes at a slow, or negligible rate.

  3. Inert gas - Wikipedia

    en.wikipedia.org/wiki/Inert_gas

    An inert gas is a gas that does not readily undergo chemical reactions with other chemical substances and therefore does not readily form chemical compounds. Though inert gases have a variety of applications, they are generally used to prevent unwanted chemical reactions with the oxygen ( oxidation ) and moisture ( hydrolysis ) in the air from ...

  4. Reaction intermediate - Wikipedia

    en.wikipedia.org/wiki/Reaction_intermediate

    In chemistry, a reaction intermediate, or intermediate, is a molecular entity arising within the sequence of a stepwise chemical reaction. It is formed as the reaction product of an elementary step, from the reactants and/or preceding intermediates, but is consumed in a later step. It does not appear in the chemical equation for the overall ...

    This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...

    Inert knowledge, information which one can express but not use; Inert ingredient, a component of the excipient of a pharmaceutical drug; Inert munition, a round that does not contain any energetic material; Inert prime, a type of behaviour of a prime under an algebraic extension; Inert waste, waste which is neither chemically nor biologically ...

  7. Thermal decomposition - Wikipedia

    en.wikipedia.org/wiki/Thermal_decomposition

    Thermal decomposition, or thermolysis, is a chemical decomposition of a substance caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing

  8. Saturated and unsaturated compounds - Wikipedia

    en.wikipedia.org/wiki/Saturated_and_unsaturated...

    A saturated compound is a chemical compound (or ion) that resists addition reactions, such as hydrogenation, oxidative addition, and binding of a Lewis base. The term is used in many contexts and for many classes of chemical compounds. Overall, saturated compounds are less reactive than unsaturated compounds.

  9. Polytetrafluoroethylene - Wikipedia

    en.wikipedia.org/wiki/Polytetrafluoroethylene

    Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. [3] The commonly known brand name of PTFE-based composition is Teflon by Chemours, [4] a spin-off from DuPont, which originally invented the compound in 1938. [4]
