Hello there, I would be grateful if anybody could help me with this question...
Sodium can form three oxides:
sodium oxide, Na2O
sodium peroxide, Na2O2
sodium superoxide, NaO2
It has been suggested that sodium superoxide could be used in spacecraft to
regenerate oxygen.
Oxygen needs to be replaced in a spacecraft because an astronaut oxidises glucose, according to the equation:
C6H12O6+ 6O2 → 6CO2+ 6H2O
Sodium superoxide can regenerate oxygen according to the equation:
4NaO2 + 2CO2 → 2Na2CO3+ 3O2
In order to maintain the correct percentage of oxygen in the air, any excess carbon dioxide could be removed by using sodium oxide.
Na2O + CO2 → Na2CO3
(a) Calculate the mass of sodium oxide that would be required to remove the excess
carbon dioxide when exactly 880 g of sodium superoxide is reacted per day.
You can assume that an astronaut oxidises 2 mol of glucose each day.
The MS gives an answer of 248g and I was wondering if anybody could help me figure out how they got that. Thanks again.
