As its name implies, hydrogen was first observed in water. Water consists of one oxygen atom bonded with two atoms of hydrogen. The abundance of water on Earth makes it the most common source of hydrogen on the planet. Pure hydrogen is rare on Earth, however, due to its propensity to react in the presence of oxygen and precipitate out as water vapor.Continue Reading
Atomic and molecular hydrogen are most common beyond the Earth. Hydrogen is the primary constituent of the Sun, as well as most other stars, and it can be observed in vast quantities throughout the universe. Often, hydrogen forms the major component of certain nebulae, the so-called "stellar nurseries," which incubate the next generation of stars.
Hydrogen is also the main component of the atmospheres of gas giant planets. Jupiter, Saturn, Uranus and Neptune all have a proliferation of hydrogen and various compounds of hydrogen in their chemistry. This hydrogen-rich chemistry is an important distinction when describing a planet. Because hydrogen and oxygen cannot be held in equilibrium within the same atmosphere, a planet can be described by which gas dominates its air. An oxygen-rich world, such as Earth, is said to have an oxidizing atmosphere, while a hydrogen-rich world, such as Jupiter, has a reducing one.Learn more about Chemistry
Sodium silicate received the name "water glass" from ancient alchemists because it takes the form of pieces of glass when dry, but it also dissolves in water to form a viscous liquid. Sodium oxide or sodium carbonate reacted with silica, which is sand, forms sodium silicate.Full Answer >
The name given to the bond between water molecules is a hydrogen bond. These bonds occur between the slightly negative oxygen of one water molecule and the slightly positive hydrogen of another water molecule. Hydrogen bonding gives water special physical properties.Full Answer >
Silver hydroxide is a chemical compound composed of one atom each of silver, hydrogen and oxygen. The chemical formula for the compound is AgOH. It has a molar mass of 123.9 grams, of which silver comprises approximately 86 percent.Full Answer >
Although the chemical composition of wood varies from species to species, wood is primarily composed of carbon, hydrogen, oxygen, calcium, potassium, sulfur, nitrogen and magnesium. Most wood contains some amount of water as well.Full Answer >
