Is water a hydrate?
hydrate, any compound containing water in the form of H2O molecules, usually, but not always, with a definite content of water by weight. The best-known hydrates are crystalline solids that lose their fundamental structures upon removal of the bound water.
How are hydrates named?
Hydrates are named by the ionic compound followed by a numerical prefix and the suffix “-hydrate. ” The “· nH2O” notation indicates that “n” (described by a Greek prefix) number of loosely bonded water molecules are associated per formula unit of the salt. An anhydride is a hydrate that has lost water.
Which molecule do scientists believe came first?
Scientists have inferred that helium hydride was this first, primordial molecule. Once cooling began, hydrogen atoms could interact with helium hydride, leading to the creation of molecular hydrogen — the molecule primarily responsible for the formation of the first stars.
