### Balancing Of the Chemical Equations

The chemical equations are the representation of the Chemical Reactions. To represent the reaction that is taking place we use the chemical symbols.
The Chemical equation has 2 parts basically. These are:

Reactants

Products

Reactants are the substances that combine in the Chemical Reaction and the Products are the substances that are the result of the Chemical Reaction.

Balancing the Chemical Equations means to make the number of the atoms on both reactants and products side same. Let us try to understand the concept by taking a very simple example

Here, in the Reactants side Hydrogen  has 1 atom and Oxygen has 2 atoms. On the Product Side we have 2 atoms of Hydrogen and 1 atom of Oxygen.
Balancing the equation means that we have to make the number of Oxygen and Hydrogen atoms same at both the ends. That can be done by applying the following steps :
Step 1 –  Balance Hydrogen first.
2H + O2 ——-H2O
Here, adding a 2 as a prefix with H at the Reactants side made Hydrogen balanced.
Step 2:  Balancing Oxygen
2H + O2 ——-2H2O
This balanced the oxygen but, balancing of hydrogen is disturbed as at the product side H atoms becomes 4 and they are 2 in reactants side.

Step 3: Balancing Hydrogen
4H + O2 ———2H2O
Hence, the given chemical equation is balanced.
EXAMPLE 2:
Let us try out one of a bit complicated equations.
Let us Consider :
Balance C2H6O + O2 —–> CO2 + H2O
If you have a look to this equation carefully then you will observe that on the reactants side the number of Carbon (C) is 2, Hydrogen (H) is 6, and Oxygen (O) is 3. Comparatively, on the Product side, Carbon (C) is 1, Oxygen (O) is 3, Hydrogen (H) is 2

Step 1 :  Balancing Carbon
C2H6O + O2 —–> 2CO2 + H2O
Here, putting 2 as the coefficient (on product side) for C made it balanced.

Step 2: Balancing Hydrogen:
C2H6O + O2 —–> 2CO2 + 3H2O
Hence Hydrogen is balanced.

Step 3: Balancing Oxygen:
C2H6O + O2 —–> 2CO2 + 3H2O
Oxygen on both sides is having 3 atoms so that is balanced.

This is the way you can balance the equation.

If you are clear, try out some examples:

___ N2 + ___H2 ——-NH3

___ KCL + ___O2——–KCLO3

___ NaCl + ___ F2——–___ NaF + ___ Cl2
