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:
When a solid turns to a gas.
Explanation:
The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Calcium Chloride, or 110.984 grams.
Answer:
Hello is there a specific aliment you have in mind If so I can explain and tell you the answer.
1.5 L KNO3 solution* (2.0 mol KNO3/ 1 L KNO3 solution)= 3.0 mol KNO3.
The correct answer is (3) 3.0 mol.
Hope this would help~
