Question

Water is made up of what two elements?

Answer 1

Hint: We need to know that the water is an inorganic compound which does not have any taste and odor. And the water is a volatile liquid which is transparent in nature. The particles present in the liquid are far apart. Hence, it can easily move very easily due to the less intermolecular attraction between the particles. The water does not have any definite shape, but it has a definite volume. The shape will depend upon the container.

Complete answer:
As we know that the water is made up of two elements which are hydrogen atom and oxygen atom. It is an inorganic compound having the molecular formula, \[{H_2}O\]. The atoms present in the water are in a definite proportion. The water is prepared by mixing hydrogen gas and oxygen gas. And we have to add sufficient heat to supply the activation energy to initiate the reaction. Then there is a formation of water molecules. The reaction of formation of water can be written as,
\[2{H_2} + {O_2} \to 2{H_2}O + Energy\]
Here, two moles of hydrogen are reacted with one mole of oxygen and there is a formation of two moles of water with elimination of energy. Here each hydrogen is covalently bonded with the oxygen by sharing the pair of electrons. Two unshared pairs of electrons are present in the oxygen.

Note:
The water is made up of oxygen and hydrogen gases. And it is prepared by mixing two gases in the presence of sufficient heat. The water has a simple molecular structure which contains one oxygen atom and two hydrogen atoms. The water is a polar compound which is used as an excellent solvent. And the water has a high heat of vaporization and heat capacity.
