Answer:
A polar molecule may have one or more lone pairs.
A polar molecule has an uneven distribution of electron density.
Explanation:
A molecule in which the dipole bonds will not cancel is a polar molecule. It depends on the geometry of the molecule, and the direction of the dipole. So, to be polar, the molecule must have at least one polar bond. It may have nonpolar bonds, but the total dipole must be different from 0.
A polar bond is formed between elements that have large differents in electronegativities, such as chlorine and hydrogen. When an atom has a large electronegativity, it has lone pairs of electrons in a bond because it has a small size and a great number of electrons in the valence shell. So, a polar molecule may have on or more lone pairs.
Because of the lone pairs presented, and because of the dipole different from 0, it will be partial charges in the atoms, so a polar molecule has an uneven distribution of electrons density.
Answer:
The equilibrium will remain at the same conditions because there is no effect and difference in the partial pressure which in turn affect the equilibrium state.
Explanation:
- As Nitrogen is an inert gas therefore it will not react with either the reactants or products.
- Also as the addition is being made by maintaining the volume of flask as constant, thus there will be no difference in the partial pressure of the individual components of the mixture by addition of the Nitrogen gas.
- An increase in pressure is observed but the effect is not aiding or retreating the equilibrium conditions
