1. The problem statement, all variables and given/known data The reaction of calcium hydride and water produces calcium hydroxide and hydrogen as products. How many moles of H2 gas will be formed in the reaction between 0.80 mol CaH2 solid and 1.29 mol H2O liquid? (Two Significant Digits): 2. Relevant equations 3. The attempt at a solution Well the balanced equation for this reaction I believe is CaH2 + 2H2O -> Ca(OH)2 + H2. Therefore the molar ration is about 2:1 so if 1.29 mol is reacts than 0.645 will be formed? But I'm always wrong? Any help is appreciated.
