A subadditive function is a function, having a domain A and an ordered codomain B that are both closed under addition, with the following property: An example is the square root function, having the non-negative real numbers as domain and codomain, since we have:
Sbf5 is a nonpolar bond because the dipole moment is nonexistent. If you were to draw the chemical structure you would see that due to electronegativity of the fluorine atoms, that the vectors where the electrons are pulled away from the SB cancel one another, forcing SbF5 to be a nonpolar covalent molecule. non-polar compound occurs when there is an equal sharing of electrons between two different atoms. Examples of household non-polar compounds include fats, oil and petrol/gasoline.
A molecule of ammonia also contains a permanent diploe. Thus, even though water and gaseous ammonia are electrically neutral, both molecules are polar. The high solubility of the polar ammonia molecules in water is facilitated by strong interactions with polar water molecules.Ammonia in the form of ammonium ions.Click on image for credit.The reason why thereâs an extra proton (H+) with ammonia is because due to the fact that it is highly polar, it will attract a hydrogen atom of a water molecule (which it has dissolved in; aqueous solution) and form a fourth hydrogen bond with it.mmonia in the form of ammonium ions.
