Answer:
Partial pressure of Ne is 0.61 atm.
Explanation:
Mole fraction of a gas 
in mixture = (no. of moles of the gas in mixture)/(total no. of moles of gases in mixture)
Here, total no. of moles of gases = (0.32 + 0.56) moles = 0.88 moles
So, mole fraction of Ne in mixture, 
Let's assume both He and Ne along with their mixture behaves ideally,
Hence, in accordance with Dalton's law of partial pressure-
Where, 
and 
are partial pressure of Ne and total pressure respectively.
So, 
So, partial pressure of Ne is 0.61 atm.
The answer to this question it true
Answer:
The highest-numbered shell is the third shell, which has 2 electrons in the 3s subshell and 3 electrons in the 3p subshell.
Explanation:
Answer:
3.22
Explanation:
The pOH is defined as:
pOH = - log [OH⁻]
From the problem, we have [OH⁻] = 6.0 x 10⁻⁴.
Thus, we introduce the concentration in the equation to calculate the pOH:
pOH = - log [OH⁻] = -log (6.0 x 10⁻⁴) = 3.22
