Oxygen is the only element in that list, the rest are compounds.
There are 11 electrons in Sodium(Na)
The first shell can hold 2 electrons
The second shell can hold 8 electrons
The third shell can also hold 8 electrons but there is only 1 left
so the answer is 2, 8, 1
It should be about 0.586620881 kilograms
Two astronauts would exhale about 40 moles of carbon dioxide daily.
Carbon dioxide reacts with lithium hydroxide in a 1 : 2 mole ratio. Set up a proportion:
1 : 2 = 40 : x
Then, find x:
<span>12=40x
</span>
Cross multiply. x = 80 moles of LiOH per day for both astronauts
