Subscript - Practical applications

The subscript tag, same as the superscript tag can be used at writing the mathematical expressions. Still, the place where we mostly find it is the chemical formulas.

html<p>
	H<sub>2</sub>0 - Water<br />
	O<sub>2</sub> - Oxygen<br />
	CO<sub>2</sub> - Carbon dioxide<br />
	H<sub>2</sub>SO<sub>4</sub> - Sulfuric acid
</p>

As you can see in the example presented above its use is very practical.
