Calcium hydride, CaH2, reacts with water to form hydrogen gas:CaH2(s)+2H2O(l)→Ca(OH)2(aq)+2H2(g) This reaction is sometimes usedto inflate life rafts, weather balloons, and the like, where asimple, compact means of generating H2 is desired.
Part A
How many grams of CaH2 are needed to generate 146 L of H2 gas ifthe pressure of H2 is 824 torr at 22 ∘C?
The metabolic oxidation of glucose, C6H12O6, in our bodiesproduces CO2, which is expelled from our lungs as a gas:C6H12O6(aq)+6O2(g)→6CO2(g)+6H2O(l)
Part A
Calculate the volume of dry CO2 produced at body temperature (37∘C) and 0.990 atm when 23.5 g of glucose is consumed in thisreaction
Part B
Calculate the volume of oxygen you would need, at 1.00 atm and298 K, to completely oxidize 53 g of glucose.
