Sodium (Na) is an explosive metal, while Chlorine (CI) is a toxic gas. However, when bonded together they form regular table sal
RUDIKE [14]

Answer:

When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.

Explanation:

The term suspension means mixing of small and light particles together which are not dissolved in a fluid.

Therefore, clay, slit, and sand would be carried by suspension as they have small particles as compared to small pebbles and large rocks.

In a rock, there might be substance which are soluble in water. These soluble substances are therefore, continuously removed from the rock by the action of water.

Hence, holes will appear in the rock leading to rills and rough surface. Ultimately, the rock will either decompose or fall into pieces. On acidification of water by organic and inorganic solvents, the dissolution of rock increases.

Thus, it is concluded that in solution, rocks are dissolved by salts and acids.

What happens on a molecular level when a diatomic molecule is a gas but is then cooled to a solid?
irina1246 [14]

Answer:

As an example of the processes depicted in this figure, consider a sample of water. When gaseous water is cooled sufficiently, the attractions between H2O molecules will be capable of holding them together when they come into contact with each other; the gas condenses, forming liquid H2O. For example, liquid water forms on the outside of a cold glass as the water vapor in the air is cooled by the cold glass.

Explanation:

Hopefully that helps!
