Answer : The pOH of pure water is, 6.68
Explanation :
As we are given that:
First we have to calculate the concentration of hydroxide ion.
As,
As we know that in pure water the hydrogen ion and hydroxide ion concentration are equal. That means,
So,
Now we have to calculate the pOH.
Therefore, the pOH of pure water is, 6.68
Metals tend to lose electrons in order to attain an e-configuration isoelectronic with a noble gas; or gain stability in the form of a half or full outer subshell. Non metals gain electrons to gain an isoelcetronic noble gas structure.

Explanation:
The kinetic energy of gas molecules is related to the temperature of the gas because temperature is a measure of the average kinetic energy of the molecules of a gas hence the lower the temperature of the gas the lower the average kinetic energy of the molecules of the gas.
The volume of a given mass of gas is directly proportional its absolute temperature(Charles's law). Hence, as the temperature of the gas gas decreases, the gas volume also decreases.
The number of gas molecules is totally independent of the temperature of the gas hence it stays the same.
As the temperature decreases, the number of collision of gas particles decreases as the kinetic energy of the gas particles decreases.
The pressure of a given mass of gas is related to the movement of gas particles. Hence, the lower the temperature the lower the pressure of the gas. Pressure and temperature are directly related hence pressure decreases as temperature decreases.
