Question

Lithium hydride is used in the synthesis of other useful hydrides​

Answer 1

Answer:

Lithium hydride is by no means unreactive towards air. In powdered form it can react with air at low humidity forming the oxide, hydride and carbonate; if the air has higher humidity lithium hydride can combust spontaneously. Pellets are less violent but still not fully stable in air containing water vapor (as air typically does).
