WebAug 10, 2024 · Uses. It aids in the identification of gram-negative bacteria on the basis of their ability to oxidize or ferment a specific carbohydrate. It is used to determine whether an organism uses carbohydrate substrates to produce acid byproducts. Non fermentative bacteria are routinely tested for their ability to produce acid from six carbohydrates ... 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. Most of … See more The noble gases (helium, neon, argon, krypton, xenon and radon) were previously known as 'inert gases' because of their perceived lack of participation in any chemical reactions. The reason for this is that their outermost See more • Noble metal See more The term inert may also be applied in a relative sense. For example, molecular nitrogen is an inert gas under ordinary conditions, existing as diatomic molecules, N 2. The presence of a strong triple covalent bond in the N 2 molecule renders it unreactive under … See more gradient grain background
