Calcium Hydride (CaH₂,42 $\to$ Ca(OH)₂(s)+ 2H₂(g)
A)8

Calcium hydride (CaH₂,42.10 g/mol) is so reactive with water (18.02 g/mol) that it can be used to remove traces of water from nonaqueous solvents.What mass of the excess reactant will be left over if 24.6 g CaH₂ is added to a large volume of solvent that contains 14.0 g H₂O? CaH₂(s) + 2H₂O( ) $\to$ Ca(OH) ₂(s) + 2H₂(g)

A) 8.24 g CaH₂ will be left over.
B) 5.26 g H₂O will be left over.
C) 16.4 g CaH₂ will be left over.
D) 3.45 g H₂O will be left over.
E) Both are completely comsumed.
