Question

answer the following in detail with example what is the use of chemical formula define chemical equation and chemical reaction​

Answer 1

Answer:

A chemical equation shows the starting compound(s)—the reactants—on the left and the final compound(s)—the products—on the right, separated by an arrow. In a balanced chemical equation, the numbers of atoms of each element and the total charge are the same on both sides of the equation. A chemical formula is a notation used by scientists to show the number and type of atoms present in a molecule, using the atomic symbols and numerical subscripts. A chemical formula is a simple representation, in writing, of a three dimensional molecule that exists

Explanation:

This is extra for more information

Formulae are important because it is difficult to learn the whole names of compounds formed. For example salt is Sodium Chloride. Sometime this name cannot be remembered so the short form for it has been made that is NaCl. Also we can make the formulae. For example Water - If we don't know the symbol the thing we do is as follows -

First find out the symbol of Hydrogen

That is H

Now we know that it has only one electron and needs other Hydrogen to balance so we take H2

Now we know water also has Oxygen So we just add a

O that becomes

H2O
