Hace 2 días · Hydrogen sulfide is a chemical compound with the formula H 2 S.It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. Swedish chemist Carl Wilhelm Scheele is credited with having discovered the chemical composition of purified hydrogen sulfide in 1777.
Hace 5 días · Heavy water is water composed of deuterium, the hydrogen isotope with a mass double that of ordinary hydrogen, and oxygen. Heavy water is used as a moderator of neutrons in nuclear power plants. It is also employed as an isotopic tracer in studies of chemical and biochemical processes.
Hace 2 días · It was 107 years from Thomsen's prediction before oganesson was successfully synthesized, although its chemical properties have not been investigated to determine if it behaves as the heavier congener of radon. In a 1975 article, American chemist Kenneth Pitzer suggested that element 118 should be a gas or volatile liquid due to relativistic ...
Hace 3 días · Arsenic is a notoriously toxic heavy metal. It occurs naturally in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. It has various allotropes, but only the grey form, which has a metallic appearance, is important to industry.

Hace 4 días · sulfuric acid, dense, colourless, oily, corrosive liquid; one of the most commercially important of all chemicals. Sulfuric acid is prepared industrially by the reaction of water with sulfur trioxide ( see sulfur oxide ), which in turn is made by chemical combination of sulfur dioxide and oxygen either by the contact process or the ...
Hace 4 días · Unlike solids, which have a fixed volume and shape, liquids have a definite volume but take the shape of their container. This property makes liquids essential in various applications, from daily life to scientific research. The molecules in liquids are in constant motion.
