It has been always a terrible headache for most of the students to learn about chemical equations and balancing.
But actually, it is very easy to understand and balance.
This would be a helpful blog to all teachers and parents, to teach their children, "how to Balance Chemical Equations?"
Lets start with,
Students love to play. You can teach balancing chemical equations in a very simple manner with this.
What is a Chemical Equation ?
A and are different compounds in chemistry. Let us assume A as red color and B as yellow color. When both join, it forms AB (orange color). This is termed as chemical reaction. Equation formed from this reaction A + B = AB is chemical equation.
Balancing Chemical Equations :
The number of compounds in LHS must be equal to the number of compounds in RHS. IT is known as balancing equaton.
Consider the above example, we have 1 A, 1 B in LHS. Similarly, 1 A and 1 B in RHS. Hence, it is a balanced equation.
If LHS is not equal to RHS, it is unbalanced equation.

Why Chemical Equations should be Balanced?
- A chemical equation needs to be balanced in order to obey the “Law of Conservation of Energy”.
- Law of Conservation of Energy states that matter can never be created, nor destroyed.
- Hence, we balance equations by adding coeffiecients in front of reactants and products.
Before starting to balance equations, let us learn some reules and steps in order to balance,
Rules :
- Only the coefficients should be changed.
- Subscripts should not be changed. Changing it will change the compound.
- The lowest possible whole number should be used as coefficients.
There are four steps to be followed, let us consider it with an example,
Step 1 : Write the Formula for the equation.
H2 + O2 = H2O
Step 2 : Compare the number of atoms in left side with the right side.
LHS RHS
H = 2 H= 2,
O= 2 O =1
Step 3 : Analyse where to place the coefficients, so as to make left and right side equal.
In order to balance, we now add 2 to the RHS, making it as 2H2O, Now, equation becomes as
H2 + O2 = 2H2O
LHS RHS
H = 2 H= 4,
O= 2 O =2
H is not equal , hence add 2 to the H of LHS, forming
2H2 + O2 = 2H2O
Step 4 : Verify finally, if all the atoms in left and right side are equal.
LHS RHS
H = 4 H= 4,
O= 2 O =2
Hence, it is balanced.
