The lowest energy peak for Gallium will be associated with one electron. This is because the configuration of Gallium is:
[Ar], 3d¹⁰, 4s², 4p¹
The one unpaired electron in the 4p orbital is at lower energy than the pair in the 4s orbital. Therefore, it will be released easily via the photoelectric effect.
Answer: The vapor pressure of the solution at is 137 torr
Explanation:
As the relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.
The formula for relative lowering of vapor pressure will be,
where,
= relative lowering in vapor pressure
i = Van'T Hoff factor = 1 (for non electrolytes)
= mole fraction of solute =
Given : 13.06 g of napthalene is present in 100 g of solution, thus (100-13.06) g = 86.94 g of hexane
moles of solute (napthalene) =
moles of solvent (hexane) =
Total moles = moles of solute (napthalene) + moles of solvent (hexane) = 0.102 + 1.01 = 1.112
= mole fraction of solute (napthalene) =
Thus the vapor pressure of the solution at is 137 torr

Your wight on the earth is greater because it has more gravitational pull whilebon the moon your weight is lower beacause of less gravitational pull.
There can be an electrolytic cell from iron and copper electrodes by connecting a a battery.
<h3>What is a voltaic cell?</h3>
A voltaic cell is a cell that produces energy via a spontaneous chemical reaction. An electrolytic cell produces energy by a nonspontaneous chemical reaction.
Now, we know that we can reverse the electrodes in the voltaic cell and connect a cell. In such case, we can be able to create an electrolytic cell from iron and copper electrodes.
