In chemistry, the pentazenium cation (also known as pentanitrogen) is a positively-charged polyatomic ion with the chemical formula N + 5 and structure N−N−N−N−N.Together with solid nitrogen polymers and the azide anion, it is one of only three poly-nitrogen species obtained in bulk quantities.
In chemistry, azide (/ ˈ eɪ z aɪ d /, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure − N=N + =N −. It is the conjugate base of hydrazoic acid HN 3. Organic azides are organic compounds with the formula RN 3, containing the azide functional group. [1] The dominant application of azides is as a propellant in ...
Rb 2 SO 4 + Ba(N 3) 2 → 2 RbN 3 + BaSO 4. In at least one study, rubidium azide was produced by the reaction between butyl nitrite, hydrazine monohydrate, and rubidium hydroxide in the presence of ethanol: C 4 H 9 ONO + N 2 H 4 ·H 2 O + RbOH → RbN 3 + C 4 H 9 OH + 3 H 2 O. This formula is typically used to synthesize potassium azide from ...
Change in volume with increasing ethanol fraction. The molar volume of a substance i is defined as its molar mass divided by its density ρ i 0: , = For an ideal mixture containing N components, the molar volume of the mixture is the weighted sum of the molar volumes of its individual components.
A nitrate nitrite, or nitrite nitrate, is a coordination complex or other chemical compound that contains both nitrite (NO − 2) and nitrate (NO − 3) anions.They are mixed-anion compounds, and they are mixed-valence compounds.
Historically, the mole was defined as the amount of substance in 12 grams of the carbon-12 isotope.As a consequence, the mass of one mole of a chemical compound, in grams, is numerically equal (for all practical purposes) to the mass of one molecule or formula unit of the compound, in daltons, and the molar mass of an isotope in grams per mole is approximately equal to the mass number ...
The 15 N: 14 N ratio is commonly used in stable isotope analysis in the fields of geochemistry, hydrology, paleoclimatology and paleoceanography, where it is called δ 15 N. [40] Of the thirteen other isotopes produced synthetically, ranging from 9 N to 23 N, 13 N has a half-life of ten minutes and the remaining isotopes have half-lives less ...
Many stoichiometric phases are usually present for most elements (e.g. MnN, Mn 6 N 5, Mn 3 N 2, Mn 2 N, Mn 4 N, and Mn x N for 9.2 < x < 25.3). They may be classified as "salt-like" (mostly ionic), covalent, "diamond-like", and metallic (or interstitial ), although this classification has limitations generally stemming from the continuity of ...
