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.

vampirchik [111]

Answer:

a. pH paper can tell you the pH. pH paper only can turn a variety of colors that represent different pH numbers.

B. Litmus paper only tells you acid or base in order to turns red or blue color.

Explanation:

pH paper is a type of paper which is used for the identification of pH of the substance. On pH paper, colors are present which shows pH numbers of a solution while litmus paper is a type of paper which is used for the identification of solution whether it is acidic or basic. There are two colors i. e. Red and Blue. If the litmus paper turns red, the solution is acidic or if the litmus paper turns blue, the solution is alkaline or basic.
