Question

What is balancing of chemical equations?
give suitable example..

Answer 1

A reaction which has an equal no. of atoms of all elements on the both side is called balanced chemical equations.
eg H2 + Cl2 = HCl
on balancing-
H2 +Cl2 = 2HCL

Answer 2

Answer:

Balancing of chemical equations:-

The process of making the number of different types of atoms equal on the both the sides of an equations is known as balancing of chemical equations.

Example:-

             Zn + HCl ---> ZnCl2 + H2

There are two chlorines on the right but only one on the left, and the chlorine is in a single chemical species on each side . Put a 2 in front of the HCl on the left hand side.

              Zn + 2HCl ---> ZnCl2 + H2

And if you look carefully, you will see that the equation is now balanced, with one Zn on each side, two hydrogens on each side and two chlorines on each side.
