Did you know?
WitrynaThe correct answer is LiH. Metallic hydride, also known as an interstitial hydride, is a type of hydride that forms hydrogen bonds with transition metals. These hydrides are non-stoichiometric, meaning that the proportion of hydrogen atoms to metals is not constant. The metal is heated with hydrogen under high pressure to produce hydrides. Witryna1 wrz 2007 · A binary metal hydride is usually prepared from a reaction between metal and hydrogen. Presence of oxygen in any form is considered detrimental to the synthesis and all water is avoided. In this study, we have shown that a hydride can be synthesized directly by a reaction between a metal and water or a water-bearing solid. ... LiH, …
