Calcium hydride CaH2 chemical formula, molecular weight 42.096. 816 ° C melting point. White powder. Ion - type salt compounds. Heating melting point less than they decomposition, with the water violent reaction of hydrogen released H2O CaH2 +2 = Ca (OH) 2 +2 H2 � calcium hydride is strong reductive. Reductant used stronger, and work in the field of hydrogen used to the system. Calcium flow in heating hydrogen can be obtained calcium hydride.
