CBSE 2023 Chemistry:  How to Balance Any Chemical Equation in 30 Seconds

Let's learn quick and simple ways to balance chemical equations in this post.

+

Each element must have the same number of atoms on both sides of the equation when balancing equations.

Step 1

Step 2

Multiply coefficients in order to equalise the number of atoms of each element on both sides of the equation.

Step 3

Start balancing with less common elements first, such as metal atoms or oxygen, and leave hydrogen atoms for last.

Step 4

Be sure to total all the atoms of each element on each side of the equation. If they are not the same, rework the coefficients and subscripts.

S  + O  ⇒ SO Atoms on each side are:  S=8 on L.H.S and S=1 on R.H.S O=2 on L.H.S and O=2 on R.H.S.

For example:

To equalise, multiply by 8,  S  + 8O  ⇒ 8SO    Now,  S=8 on L.H.S and S=1*8=8 on R.H.S  O=2*8=16 on L.H.S and O=2*8=16 on R.H.S  Now the equation is balanced.
