Question:

The reaction of calcium hydride with water can be used to prepare small quantities of hydrogen gas, as is done to fill weather-observation balloons.

CaH₂(s) + H₂O(l) → Ca(OH)₂(s) + H₂(g) (not balanced)

(a) How many grams of H₂(g) result from the reaction of 127 g CaH₂ with an excess of water?

(b) How many grams of water are consumed in the reaction of 56.2 g CaH₂?
