Calcium hydride (CaH2) is so reactive with water that it can be used to remove traces of water from solvents other than water. If 24.6 g of calcium hydride is added to a large volume of solvent that contains 14.0 g of water, which of these remains, water or calcium hydride, after the reaction is complete? The reaction is: CaH2(s) + 2H20(1) - Ca(OH)2(s) + 2H2(g)
A. There is no way to tell.
