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.
Purging (gas) – the introduction of an inert (i.e. non-combustible) purge gas into a closed system (e.g. a container or a process vessel) to prevent the formation of an ignitable atmosphere, a fire and explosion prevention procedure to avoid the formation of an ignitable atmosphere, accomplished by flushing a closed system with an inert gas
Krypton is less reactive than xenon, but several compounds have been reported with krypton in the oxidation state of +2. [40] Krypton difluoride is the most notable and easily characterized. Under extreme conditions, krypton reacts with fluorine to form KrF 2 according to the following equation: Kr + F 2 → KrF 2
Acidic foods, like tomatoes, will have a chemical reaction based on the type of cookware you use.
For example, the statement that "sodium metal is reactive" suggests that sodium reacts with many common reagents (including pure oxygen, chlorine, hydrochloric acid, and water), either at room temperature or when using a Bunsen burner. The concept of stability should not be confused with reactivity.
The premise of the NST is that a well-oxygenated, non-acidemic fetus will spontaneously have temporary increases, termed "accelerations," in the fetal heart rate (FHR). [2] Vibroacoustic stimulation can wake the fetus, and is sometimes used to speed up the test or to facilitate further evaluation of a non-reactive nonstress test. [3]
The most reactive metals, such as sodium, will react with cold water to produce hydrogen and the metal hydroxide: 2 Na (s) + 2 H 2 O (l) →2 NaOH (aq) + H 2 (g) Metals in the middle of the reactivity series, such as iron , will react with acids such as sulfuric acid (but not water at normal temperatures) to give hydrogen and a metal salt ...
It's Advent calendar season, and if you haven't picked up your treat for the year, you may have missed your window. Many of the year's best Advent calendars have sold out already, like the Bonne ...
