Ammonium nitrate is a chemical compound with the formula NH 4 NO 3. It is a white crystalline salt consisting of ions of ammonium and nitrate. It is highly soluble in water and hygroscopic as a solid, but does not form hydrates. It is predominantly used in agriculture as a high-nitrogen fertilizer. [5]
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 ...
Manganese oxalate forms light pink crystals. The crystalline hydrates have the composition MnC 2 O 4 •n H 2 O, where n = 2 and 3. [7] The dihydrate forms light pink crystals of the orthorhombic system, space group P2 1 2 1 2 1, cell parameters a = 0.6262 nm, b = 1.3585 nm, c = 0.6091 nm, Z = 4, melts in its own crystallization water at 100 °C.
The Born–Landé equation is a means of calculating the lattice energy of a crystalline ionic compound.In 1918 [1] Max Born and Alfred Landé proposed that the lattice energy could be derived from the electrostatic potential of the ionic lattice and a repulsive potential energy term.
Barium azide can be used to make azides of magnesium, sodium, potassium, lithium, rubidium and zinc with their respective sulfates. [4]Ba(N 3) 2 + Li 2 SO 4 → 2 LiN 3 + BaSO 4. It can also be used as a source for high purity nitrogen by heating:
Peroxynitrite is weakly basic with a pK a of ~6.8.. It is reactive toward DNA and proteins.. ONOO − reacts nucleophilically with carbon dioxide. In vivo, the concentration of carbon dioxide is about 1 mM, and its reaction with ONOO − occurs quickly.
We derive the ion acoustic wave dispersion relation for a linearized fluid description of a plasma with electrons and ion species. We write each quantity as X = X 0 + δ ⋅ X 1 {\displaystyle X=X_{0}+\delta \cdot X_{1}} where subscript 0 denotes the "zero-order" constant equilibrium value, and 1 denotes the first-order perturbation.
Phosphonium ion Structure of PH + 4, the parent phosphonium cation. In chemistry, the term phosphonium (more obscurely: phosphinium) describes polyatomic cations with the chemical formula PR + 4 (where R is a hydrogen or an alkyl, aryl, organyl or halogen group). These cations have tetrahedral structures.
