Nitrogen triiodide explosion A contact explosive is a chemical substance that explodes violently when it is exposed to a relatively small amount of energy (e.g. friction , pressure , sound , light ).
The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth 's surface, the cooling rate of the planet's interior , gravitational interactions with other objects in the Solar System , and a steady increase in the Sun's luminosity .
Octaazacubane is a hypothetical explosive allotrope of nitrogen with formula N 8, whose molecules have eight atoms arranged into a cube. (By comparison, nitrogen usually occurs as the diatomic molecule N 2.) It can be regarded as a cubane-type cluster, where all eight corners are nitrogen atoms bonded along the edges. [2]
CF Industries may have nothing to do with the potash nutrient that has faced rough waters in recent months, but its stock has under-performed nearly every other fertilizer stock year to date.
Nitrogen is a chemical element; it has symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.
Solid nitrogen is mainly the subject of academic research, but low-temperature, low-pressure solid nitrogen is a substantial component of bodies in the outer Solar System and high-temperature, high-pressure solid nitrogen is a powerful explosive, with higher energy density than any other non-nuclear material.
This is a compilation of published detonation velocities for various high explosive compounds. Detonation velocity is the speed with which the detonation shock wave travels through the explosive.
This scenario is unlikely in the foreseeable future. [138] Astroengineering projects proposed to mitigate the risk of gamma-ray bursts include shielding the Earth with ionised smartdust and star lifting of nearby high mass stars likely to explode in a supernova. [143]
