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

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