Answer:
Salt.
Explanation:
NaCl = natrium chloride, otherwise known as table salt.
Coordination numbers are defined for the crystalline structures that tell about the numbers of atoms bonded to the central atom. The coordination number of a diamond is 4.
<h3>What is a coordination number?</h3>
A coordination number has been defining the number of the ions, atoms, and molecules that are bonded to the central atom of the crystalline compound or a complex.
The diamond has 8 carbon atoms in its one unit and its coordination number is 4 as its lattice type is face-centered cubic that has carbons at the corners and face center of the structure. One carbon contributes 1/8 hence and the faces center contributes 1/2.
Therefore, the diamond has a coordination number of 4.

D. The average kinetic energy increases, and the particles collide more frequently.
Explanation:
When the temperature of a gas is increased, the average kinetic energy increases and the particles collide more frequently with one another and the walls of the container.
- The temperature of a gas is a measure of the average kinetic energy of the molecules.
- When temperature increases, the frequency of ordinary and effective collision increases per unit time.
