Explanation:
A balanced equation is defined as the equation which contains same number of atoms on both reactant and product side.
Chemical formula of sodium carbonate is [tex]Na_{2}CO_{3}[/tex] and it is formed by chemical reaction between sodium, carbon and oxygen atom as follows.
[tex]Na(s) + C(s) + O2(g) \rightarrow Na_2CO_3(s)[/tex]
To balance this chemical equation we multiply Na by 2 and [tex]O_{2}[/tex] by [tex]\frac{3}{2}[/tex] on the reactant side.
Hence, the balanced chemical equation is as follows.
[tex]2Na(s) + C(s) + \frac{3}{2}O2(g) \rightarrow Na_2CO_3(s)[/tex]
