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?
(c) What mass of CaH2(s) must react with an excess of water to produce 8.12 X 1024 molecules of H2?
