The polar covalent bonding occurs when two atoms with different electronegativity form a covalent bond. This type of connection, the electrons are not equally shared. Typically, the atom having higher electronegativity attracts the electrons in the next link to it, thus forming a negative pole in its vicinity, and a positive pole of the next region less electronegative atom.
example: In the molecule HCl, hydrochloric acid, chlorine atom is more electronegative attracting electrons proximity to the bond with the hydrogen atom that is less electronegative, or more electropositive also rated.
hope this helps!.
For the answer to the question above, the answer is simple and obvious. Measured value is simply the value that is measured.
<span>While, theoretical value is the value from theory or calculations.
I hope my answers helped you. Have a nice day!</span>

This is where something called Graham's Law applies. Grahams law says that the rate of effusion is inversely proportional to the square root of the molar mass of a gas. What that means is that the less the molar mass of a gas is, the less quickly the gas effuses (effusion being the rate at which a gas can travel through a small hole). A great way to think about this is that effusion is thought about as though the gas is traveling through a small hole, so smaller particles would be able to go through it with greater ease than would a large particle. I don't know what particular sentences the question asks for are, but the answer should be that gas A (molar mass 4) has the greatest effusion rate, gas B (molar mass 16) has the second fastest effusion rate, and gas C (molar mass 32) has the slowest effusion rate.
