Question

What is ${{H}_{2}}O$ full name?

Answer 1

Hint: ${{H}_{2}}O$ have two hydrogen atoms and one oxygen atom, as it is the molecular formula of water. As hydrogen comes under the alkali elements, it also is named as other alkali metal oxides like lithium monoxide for $L{{i}_{2}}O$, sodium oxide for $N{{a}_{2}}{{O}_{2}}$, etc.

Complete step by step answer:
In ${{H}_{2}}O$, there are two hydrogens and oxygen, therefore, its name will be dihydrogen oxide.
Water is a liquid that is a colorless, odorless, and tasteless substance. It is one of the most important things for the survival of life. The bond between hydrogen and oxygen is covalent. The angle between both the bonds is ${{104.45}^{\circ }}$ and this is due to the presence of two lone pairs on the oxygen atom.
In the gaseous form, it is steam or water vapors and in the solid form, it is ice. Its boiling point is ${{100}^{\circ }}C$ and its freezing point is ${{0}^{\circ }}C$. Almost in all sectors, water is used in agriculture, fishing, cooking, cleaning, industries, swimming, entertainment, etc. For steaming, cooling, and heating water is used.
Water is a compound that is used as a universal solvent because most of the compounds, whether solid, liquid, or gas can be dissolved in it. Usually, liquids are soluble in water because of the formation of hydrogen bonding.

Note: If want to have all the three phases of water, i.e., solid, liquid, and gas at the same time, then we have to put the temperature 273.16 K and 611.657 Pa of pressure, and this is known as the triple point of water.
