Explanation:
It is known that rate of effusion of gases are inversely proportional to the square root of their molar masses.
And, half of the helium (1.5 L) effused in 24 hour. So, the rate of effusion of He gas is calculated as follows.
= 0.0625 L/hr
As, molar mass of He is 4 g/mol and molar mass of 
is 32 g/ mol.
Now,
= 2.83
or, rate of 
= 
Rate of = 0.022 L/hr.
This means that 0.022 L of gas effuses in 1 hr
So, time taken for the effusion of 1.5 L of gas is calculated as follows.
= 68.18 hour
Thus, we can conclude that 68.18 hours will it take for half of the oxygen to effuse through the membrane.
2. chemical, thermal, and electromagnetic
X: 1S²2S²2P⁶
Y: 1S²2S²2P⁶3S²3P⁶
The statement which is most likely correct about the two elements is
They will not react because both have a complete outermost shell and are stable.
<u><em>Explanation</em></u>
The P orbital can hold a maximum of 6 electrons,therefore the 2P orbital for x and 3P orbital for Y which are outermost subshell are fully filled .
This make element Y and x stable since they cannot react either by gaining or losing electrons.
Complete Question

Answer:
The pressure is 
Explanation:
From the question we are told that
The mass of the carbon monoxide is 
The temperature at which takes place 
The volume of the sealed vessel is 
Generally the ideal gas law is mathematically represented as
Where R is the gas constant with value 
n is the number of moles of carbon monoxide which is mathematically evaluated as
where 
is the molar mass of carbon monoxide which is a constant with value
So 
Now Making P the subject we have
Answer:
Moles of substance are defined ratio of the given mass of the substance to the molar mass of the substance.
Given :
The 52.06 grams of carbon dioxide.
To find :
The moles of carbon dioxide.
Solution:
The mass of carbon dioxide = 52.06 g
The molar mass of carbon dioxide = 44.01 g/mol
The moles of carbon dioxide:
1.183 moles of carbon dioxide are there in 52.06 g of carbon dioxide.
Explanation:
