The four bonds of carbon tetrachloride (CCl4<span>) are </span>polar, but the molecule isnonpolar<span> because the bond polarity is canceled by the symmetric tetrahedral shape. When other atoms substitute for some of the Cl atoms, the symmetry is broken and the molecule becomes </span>polar
Explanation:
As we know that molecules of a gas move far away from each other because they are held by weak Vander waal forces. So, when a balloon is filled by a gas then molecules of a gas strike at its walls leading to more number of collisions.
This will also lead to more expansion of the balloon. As we know that pressure is the force exerted n per unit area of a substance or object.
Thus, more is the kinetic energy of the molecules of the gas more will be the force exerted by them. Hence, more will be the pressure exerted.

After a long while of research, for I hade the same question needing an answer as well, I finally got it. Your answer would be Glacier Scrapings.
D) 1s22s22p63s1 is the correct answer.
As we all know, there are no more than 2 electrons in the s-orbital, no more than 6 electrons in the p-orbital. In order to move to another orbital, you have to fully fill electrons in one orbital, then move to the next one.
Hope this helps~
