Answer:
16.8 L
Explanation:
From the question given above, the following data were obtained:
Number of mole of He = 0.750 mole
Volume of He =?
Recall:
1 mole of any gas occupy 22.4 L at STP. This also implies that 1 mole of He occupies 22.4 L at STP.
Finally, we shall determine the volume occupied by 0.750 mole of He. This can be obtained as follow:
1 mole of He occupied 22.4 L at STP.
Therefore, 0.750 mole of He will occupy = 0.750 × 22.4 = 16.8 L at STP.
Thus, 0.750 mole of He is equivalent to 16.8 L
The expected parameters in Stratopause are; Temperature: -15 degrees Celsius, Pressure: 1 milibar and Water vapor concentration: cannot be determined.
<u>Explanation</u>:
"Stratopause" is the interaction between the ionosphere and the stratosphere. It is 50-55 km high above the earth surface that is why temperature is very less approximately -15 degrees Celsius (5 degrees Fahrenheit). As it is a thin layer separating the stratosphere and ionosphere actual water vapor concentration cannot be determined. The atmospheric pressure is around 1/1000 of the pressure at sea level.

Answer:
~Na+1 is already in the preferred form. Because of this, the second ionization energy of sodium is higher than normal. Mg+1 loses an electron to form s2 p6 .
