Which of the following statements concerning the attraction of ions to polar molecules is/are CORRECT? 1. The force of attractio

n between an ion and a polar molecule is inversely proportional to the square of the distance between the center of the ion and the oppositely charged pole of the dipole. 2. The higher the ion charge, the stronger the attraction between the ion and a polar molecule. 3. The greater the magnitude of the dipole, the greater the attraction between the ion and a polar molecule.

Answer:

1, 2 and 3 are correct.

Explanation:

The force of the attraction is calculated by Coulomb's law as:

\frac {K\times q_1\times q_2}{d^2}

Where,  

K is the Coulomb's constant having value 9×10⁹ N. m²/C²

q_1\ and\ q_2 are the charges on the dipole and ion respectively.

d is the distance between them.

Since F is inversely proportional to square of distance between them, so statement 1 is true.

F is directly proportional to the charge , so on increasing charge, force of attraction increases. Hence, statement 2 is true.

The greater the magnitude of the dipole means the greater the charge on dipole. Hence, statement 3 is also true.

2 moles of sodium chloride are dissolved in 8 liters of water. What is its molarity (M) ?
otez555 [7]

Answer:

0.25M

Explanation:

Since molarity is defined as the amount of substance in 1 liter of a solution, and amount in chemistry refers to the number of moles, molarity can be found using the equation below:

Molarity= number of moles ÷ volume in liters

Given: number of moles= 2

Volume= 8L

∴ Molarity of NaCl

= 2 ÷8

= 0.25M

Novay_Z [31]

Answer:

The five phases of matter. There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don't move much.
