In this lesson, you will learn how gases behave when they are mixed together and how to use Dalton's law of partial pressures to calculate partial and total pressures of gases. Calcium hydroxide and hydrogen gas are produced by the reaction of calcium hydride and water. The molar mass {eq}(MM) (b) How many grams of water are consumed in the reaction of $56.2 \mathrm{g} \mathrm{CaH}_{2} ?$(c) What mass of $\mathrm{CaH}_{2}(\mathrm{s})$ must react with an excess of water to produce $8.12 \times 10^{24}$ molecules of $\mathrm{H}_{2} ?$, a. grams of $\mathrm{H} 2=12.16 \mathrm{g}$b. In the laboratory, calcium hydride is used as a drying agent for organic solvents. &=2.946\;mol Calcium hydroxide reacts with water to form hydrogen gas: CaH2(s)+2H2O(l)→ Ca(OH)2(aq)+2H2(g) C a H 2 (s) + 2 H 2 O (l) → C a (O H) 2 (a q) + 2 H 2 (g).
