Sodium peroxide is used in orbital stations for air purification.The reaction that takes place is?
Sodium peroxide is used in orbital stations for air purification.The reaction that takes place is:
#Na_2O_2+CO_2=Na_2CO_3+\frac{1}{2}O_2#
An orbital station has the volume of 220m^3.At a certain point CO2 concentration has reached 20%.What is the mass of 75% purity sodium peroxide that should have been used to lower CO2 concentration to 1%(in volumes),in normal conditions (T=273K , p=1atm) , respectively what is the volume of oxygen regenerated?

Warning! Long Answer. You must use 190 kg of the impure sodium peroxide. You regenerate
Explanation:
Step 1. Calculate the volume of
You want to reduce the volume of
Step 2. Calculate the moles of
We can use the Ideal Gas Law for this calculation.
#color(blue)(bar(ul(|color(white)(a/a)pV = nRTcolor(white)(a/a)|)))" "#
We can rearrange this formula to get
#n = (pV)/(RT)#
∴
Step 4. Calculate the moles of pure
The balanced equation is
Step 5. Calculate the mass of pure
Step 6. Calculate the mass of impure
The
Note: The answer can have only two significant figures, because that is all you gave for the percent of carbon dioxide and for the purity of the sodium peroxide.
Step 7. Calculate the volume of
Thus, the removal of 1 mol of
We can also say, "The removal of
of
Thus, the removal of
of
