Selenium falls in the same column with oxygen therefore it has the same number of valence electrons with oxygen which is 6. It fills the 3d orbital but only 4s and 4p are counted. The electronic configuration is [Ar]3d^10 4s^2.

Answer:
150
Explanation:
A gas will have the lowest rate of diffusion the lowest temperature from a given set of temperature values.
Since 150 is the lowest value, then this represents the lowest rate of diffusion.
The rate of diffusion is related to the prevalent temperature. When gases diffuse, they move from regions of high concentration to the at of low concentration. They must have enough kinetic energy to move in order to diffuse.
The higher the temperature, the more the kinetic energy and higher rate of diffusion.
Answer:
<h3>The answer is 150 kPa</h3>
Explanation:
The new pressure can be found by using the formula for Boyle's law which is
Since we are finding the new pressure
From the question we have
We have the final answer as
<h3>150 kPa</h3>
