The n-h bond in ammonia is polar because

a: nitrogen occupies more space than hydrogen.

b: hydrogen is much more electronegative than nitrogen.

c: it is a hydrogen bond.

d: it is an ionic bond.

e: nitrogen is much more electronegative than hydrogen.

The N-H bond in ammonia is polar because the nitrogen is more electronegative than the hydrogen.

Explanation:

The nitrogen atoms in a molecule of ammonia is more electronegativity than the hydrogen atoms thus making it a polar molecule.

Option E.

N-H bond in ammonia is polar because nitrogen is more electronegative than hydrogen.

Explanation:

Ammonia is a compound that contain nitrogen and hydrogen. It has a trigonal pyramidal i shape, the three hydrogen atoms and one nitrogen atom are covalently bonded together. The nitrogen atom is more electronegative and it attracts more electron to itself. The nitrogen atom is slightly negative and the hydrogen atoms are slightly positive, there is unequal sharing of electrons between the nitrogen atom and hydrogen atoms due to high attraction of electrons to nitrogen atom, this is what is refer to Polar molecule. A polar molecule I a molecule with unequal sharing of electron between the atoms.

chert is a sedimentary rock composed of microcrystalline or cryptocrystalline silica. with this little bit of information, you can come to the conclusion that your answer is c.
