The central plot of the expansion is the return of the evil dragon aspect Deathwing the Destroyer (originally Neltharion the Earth Warder). Last seen in Warcraft II, which took place more than two decades earlier, Deathwing has spent that time healing himself, and plotting his fiery return from the elemental plane of Deepholm. [5]
Two new playable races were added to World of Warcraft in The Burning Crusade: the Draenei of the Alliance and the Blood Elves of the Horde.Previously, the shaman class was exclusive to the Horde faction (available to the orc, troll and tauren races), and the paladin class was exclusive to the Alliance faction (available to the human and dwarf races); with the new races, the expansion allowed ...
Phaneritic (phaner = visible) textures are typical of intrusive igneous rocks, these rocks crystallized slowly below Earth's surface. As magma cools slowly the minerals have time to grow and form large crystals.
Cristobalite is stable only above 1470 °C, but can crystallize and persist metastably at lower temperatures. The persistence of cristobalite outside its thermodynamic stability range occurs because the transition from cristobalite to quartz or tridymite is "reconstructive", requiring the breaking up and reforming of the silica framework.
Crystallographic analysis reveals that the solid consists of [trans-NiCl 2 (H 2 O) 4] subunits that are hydrogen bonded to each other as well as two additional molecules of H 2 O. Thus one third of the water molecules in the crystal are not directly bonded to Ni 2+, and these might be termed "water of crystallization".
The degree of crystallinity is estimated by different analytical methods and it typically ranges between 10 and 80%, with crystallized polymers often called "semi-crystalline". The properties of semi-crystalline polymers are determined not only by the degree of crystallinity, but also by the size and orientation of the molecular chains.
Solubility of the system Na 2 SO 4 – H 2 O. So, whenever the conditions are favorable, crystal formation results from simply cooling the solution. Here cooling is a relative term: austenite crystals in a steel form well above 1000 °C. An example of this crystallization process is the production of Glauber's salt, a crystalline form of sodium ...
Crystallized sugar. Crystals on the right were grown from a sugar cube, while the left from a single seed crystal taken from the right. Red dye was added to the solution when growing the larger crystal, but, insoluble with the solid sugar, all but small traces were forced to precipitate out as it grew.
