The energy used to power one of the Apollo lunar missions was supplied by
the following overall reaction:
2N2H4 + (CH3)2N2H2 + 3N204 → 6N2 + 2CO2 + 8H20.
For that phase of the mission when the lunar module ascended from the
surface of the moon, a total of 1200.kg of N H4 were available to react with
1000. kg of (CH3)2N2H2 and 4500. Kg of N204.
(a) For this portion of the flight, which of the allocated components
was used up first?
(b) How much water, in kilograms, was left in the lunar
atmosphere through this reaction?
102
