Answer:
2Li(s) + 2H₂O(ℓ) ⟶ 2Li⁺(aq) + 2OH⁻(aq) + H₂(g)
Explanation:
An ionic equation uses the symbols (aq) [aqueous] to indicate molecules and ions that are soluble in water, (s) [solid] to indicate insoluble solids, and (ℓ) to indicate substances (usually water) in the liquid state.
In this reaction, solid lithium reacts with liquid water to form soluble lithium hydroxide and gaseous hydrogen
.
1. Molecular equation
2Li(s) + 2H₂O(ℓ) ⟶ 2LiOH(aq) + H₂(g)
2. Ionic equation
Lithium hydroxide is a soluble ionic compound, so we write it as hydrated ions.
2Li(s) + 2H₂O(ℓ) ⟶ 2Li⁺(aq) + 2OH⁻(aq) + H₂(g)
Owing to the arrangement of ions in NaCl, the structure has a high melting point and crystalline structure.
Ionic compounds are know to have a crystalline structure. This is because the ions in the compound are arranged into a crystal lattice. A crystal lattice gives a regular repeating structure of ions in the crystal.
As a result of this order in the crystal, the resultant sodium chloride structure has a high melting point and crystalline structure.

Explanation:
A. radiation
Explanation:
The heat transfer mechanism that causes the surface of the earth to gain heat is by radiation.
Electromagnetic radiation is able to cause the heating of the surface by radiation.
Radiation is one of the methods of heat transfer the does not involve any particle.
The surface of the earth absorb some of the radiation and it causes them to warm up.
