**we need to balance the number of atoms of elements on right hand side with the elements on the left hand side.**

**u will understand better with this example:**

**H2O----->H2 + 02**

**in this equation be need to balance the number of hydrogen atoms and the number of oxygen atoms.**

**there are 2 atoms of hydrogen and 1 atom of oxygen on the left hand side whereas there are 2 atoms of hydrogen and 2 atoms of oxygen on the right hand side.**

**we need to add 2 on the left side of H2O on the left hand side and 2 on the heft side of H2 on the right hand side.**

**these 2s gets multiplied with the number of atoms of the element beside which it lies.**

**the final equation would look:**

**2H2O -------------->2H2 + 02**
