Calcium hydride (CaH2) reacts with water to form hydrogen gas (H2): CaH2(s) + 2 H20) → CatOH)2(aq) +2 H2E) This reaction is sometimes used to inflate life rafts, weather balloons and the like, where a simple, compact means of generating H2 is desired. How many grams of CaH2 are needed to generate 53.5 L of H2 gas if the desired pressure of H2 is 108.5 kPa at 21°C?
