Answer:
c. CH4 < NH3 because the NH bond is more polar than the CH bond.
Explanation:
Actually, the electronegativity difference between carbon and hydrogen is just about 0.4. This meager difference in electronegativity corresponds to a nonpolar bond between the two atoms.
However, the electronegativity difference between nitrogen and hydrogen is about 0.9. This larger electronegativity difference corresponds to the existence of a polar covalent bond between the two atoms.
Hence the N-H bond is significantly polar unlike the C-H bond. This implies that CH4 molecules are only held together by weak dispersion forces while NH3 molecules are held together by stronger dipole-dipole interactions and hydrogen bonds.
Answer:
Your answer would be B. Increasing the distance between the water molecules and increasing their phase energy.

Answer:
The answer to your question is: Neutral
Explanation:
A neutral solution is a solution whose pH is 7.
That means that this solution has the same amount of H⁺ and OH⁻.
Examples of neutral solutions:
- distilled water
- sugar solution
- table salt
- cooking oil.
