How to balance a chemical equation?

Balanced Chemical Equation: A balanced chemical equation has number atoms of each element equal on both left and right sides of the reaction.

In order to balance chemical equations, one has to balance all the atoms on the left and

the right side of the arrow.

For example: Mg + H2SO4 --> MgSO4 + H2

 left side : Mg = 1          right side of arrow: Mg = 1

              H = 2                                  H = 2

             S = 1                                 S = 1

             O = 4                                   O = 4

As you can see that the elements on both left and right side have equal no. of atoms, therefore the equation is balanced.
