g All of the molecules below have polar bonds but only one of the molecules is a polar molecule. Which one is a polar molecule?
lbvjy [14]

Answer: NF_3

Explanation:

Geometrical symmetry of the molecule and the polarity of the bonds determine the polarity of the molecule.

The molecule that has zero dipole moment that means it is a geometrically symmetric molecule and the molecule which has some net dipole moment means it is a geometrically asymmetric molecule.

As the molecule is symmetric, the dipole moment will be zero as dipole moments cancel each other and the molecule will be non-polar.

As the molecule is asymmetric, the dipole moment will not be zero and the molecule will be polar.

Example: NF_3

Thus, we can say that NF_3 is a polar molecule.

Identify the oxidizing agent and the reducing agent for 4Li(s) + O_2 (g) to 2Li_2O(s).
Doss [256]
The reaction is:

<span>4Li(s) + O2 (g) = 2Li+  + 2O-2(s).

The oxidizing agent is the one that is being reduced which is oxygen  where the charge changed from neutral to -2 while the reducing agent is the on being oxidized which is lithium where the charge change from neutral to +1.</span>
