Calcium hydride (CaH2) reacts vigorously with water according to the unbalanced equation shown:

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

Determine the moles of H2 that could be produced if 24.6 g of calcium hydride were to undergo the reaction above. Enter a numerical value in the correct number of significant figures; do not enter units.

Determine the moles of H2 that could be produced if 14.0 g of water were to undergo the reaction above. Enter a numerical value in the correct number of significant figures; do not enter units.

If 24.6 g of calcium hydride were combined with 14.0 g of water, which substance would be completely consumed during the reaction?
