The sum of all the internal angles of a simple polygon is π(n−2) radians or 180(n–2) degrees, where n is the number of sides. The formula can be proved by using mathematical induction: starting with a triangle, for which the angle sum is 180°, then replacing one side with two sides connected at another vertex, and so on.
The prevailing model of atomic structure before Rutherford's experiments was devised by J. J. Thomson. [2]: 123 Thomson had discovered the electron through his work on cathode rays [3] and proposed that they existed within atoms, and an electric current is electrons hopping from one atom to an adjacent one in a series.
H 2 N 2 O 2 + 2 H + + 2 e − ⇌ N 2 + 2 H 2 O; E 0 = +2.65 V. Oxidation reactions usually result in the formation of the nitrate ion, with nitrogen in oxidation state +5. For example, oxidation with permanganate ion can be used for quantitative analysis of nitrite (by titration): 5 NO − 2 + 2 MnO − 4 + 6 H + → 5 NO − 3 + 2 Mn 2+ + 3 H 2 O
N 2 + 16ATP + 16H 2 O + 8e − + 8H + → 2NH 3 +H 2 + 16ADP + 16P i. The process is coupled to the hydrolysis of 16 equivalents of ATP and is accompanied by the co-formation of one equivalent of H 2. [15] The conversion of N 2 into ammonia occurs at a metal cluster called FeMoco, an abbreviation for the iron-molybdenum cofactor.
= [2] where σ {\displaystyle \sigma } represents the applied true stress on the material, ϵ {\displaystyle \epsilon } is the true strain , and K {\displaystyle K} is the strength coefficient. The value of the strain hardening exponent lies between 0 and 1, with a value of 0 implying a perfectly plastic solid and a value of 1 representing a ...

2-Nitroaniline is an organic compound with the formula H 2 NC 6 H 4 NO 2. It is a derivative of aniline , carrying a nitro functional group in position 2. [ 1 ] It is mainly used as a precursor to o-phenylenediamine.
Nickel(II) oxide is the chemical compound with the formula NiO.It is the principal oxide of nickel. [4] It is classified as a basic metal oxide. Several million kilograms are produced annually of varying quality, mainly as an intermediate in the production of nickel alloys. [5]
