the lowest vapor concentrations because the water droplets have little energy to evaporate. Aphase diagramis a core tool used in physical chemistry to understand the correlation between temperature, pressure, and the various states of a substance. Fig.1, is thephase diagram for water. It shows ...
(For a memory configuration γ∈Γ*, θ(γ) indicates the accessible information of γ by M.) δ: a partial function from (Φ∪ {ε}) x Γn to 2Ω κ: a partial function from Γn to Ψ∪{ε} γ0: an element in Γ* (called the initial memory configuration). A memory configura...

Arsenic itself is stable in dry air, but in moist air it tends to become coated with a blackoxide.Sublimedarsenic vapor readily burns in air to form arsenious oxide. The free element is essentially unaffected by water, bases, or nonoxidizing acids, but it can be oxidized bynitric acidto...
High-grade or enriched stibnite reacts directly with scrap iron in the molten state, liberating antimony metal. The metal can also be obtained byconversionof stibnite to the oxide, followed by reduction withcarbon. Sodium sulfide solutions are effective leaching agents for the concentration of stibni...
In Science, the atomic symbol Kr stands for which element that shares a name with Superman's native planet? ARE YOU THE WEAKEST LINK? Braun's icons, which swarm about his figures like nettlesome insects, derive from many different realms: forms of transportation (automobiles, airplanes, boats...

What is Argon Used for It is commonly used when an inert environment is needed, especially during the production of reactive elements like pure titanium[1]. Welders also use it for protecting the weld area[1]. It provides an inert environment to facilitate the growth of germanium and silicon...
Origin of its Name: It is named after ‘Mercury’, the fastest planet in the solar system to revolve around the Sun while its chemical symbol is derived from ‘hydrargyrum’, Greek for “liquid silver”[2, 6] Who discovered it: The element was probably discovered thousands of years ago ...
