Can anyone give me the correct balanced equation of the reaction between CaH + 2H2O with correct physical states?

Rafik Karaman

Dear Bryan,

Calcium hydride, CaH2, reacts with water to form hydrogen gas.

CaH2(s) + 2 H2O(l) Ca(OH)2(aq) + 2 H2(g)

s refers to solid, l refers to liquid, aq refers to aqueous and g refers to gas.

This reaction is sometimes used to inflate life rafts, weather balloons and etc.

Hoping this will be helpful,

Rafik
