Answer to Question #69894 in General Chemistry for Kaksh

Question

Two elements in which one is neutral gas and another is monovalent metal

Answer 1

Neutral gas is practically transparent for CMB. Now the gas pressure is determined only by the motion of neutral atoms, the elasticity of the gas falls sharply and it becomes possible to trigger the mechanism of gravitational instability. In 1964, one of the authors of the book () showed how large perturbations of the hot plasma epoch after a sharp drop in pressure can develop under the influence of gravitation in isolated bodies. Bardeen and others abroad. In the last decade, it turned out that in the formation of a large-scale structure of the universe, an important role was probably played by weakly interacting particles, which by their total mass are many times greater than, apparently, the mass of ordinary visible matter.

The neutral gas with respect to copper is nitrogen. Therefore, when arc welding of tungsten electrodes of copper and its alloys, nitrogen is used as the protective gas.

Discharge of neutral gases and vapors from process equipment to the atmosphere should be diverted to a safe place. The minimum height of the candle should be not less than 6 m from the level of the planning mark of the site.

For neutral gases, the equilibrium constants of the dissociation reactions for monatomic gases are given, for ionized positively charged gases, the equilibrium constants of the ionization reactions of the corresponding neutral gas, and for the negatively charged gases, the equilibrium constants of the electron detachment reaction.

The atoms of the neutral gas, falling at high speed into the electric arc zone, decay into electrons and ions and form a plasma.

The behavior of the neutral gas is very different from that of the ionized one. The interaction of matter and radiation is maintained by free electrons. Without them, neutral gas practically does not interact with radiation.

The neutral gas system is designed to prevent the explosion of fuel vapors in the event of a fuel tank damage.
