Question

Balanced chemical equation for the standard formation reaction of solid sodium carbonate

Answer 1

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 $Na_{2}CO_{3}$ and it is formed by chemical reaction between sodium, carbon and oxygen atom as follows.

        $Na(s) + C(s) + O2(g) \rightarrow Na_2CO_3(s)$

To balance this chemical equation we multiply Na by 2 and $O_{2}$ by $\frac{3}{2}$ on the reactant side.

Hence, the balanced chemical equation is as follows.

          $2Na(s) + C(s) + \frac{3}{2}O2(g) \rightarrow Na_2CO_3(s)$      

Answer 2

CO2 + 2 NaOH → Na2CO3 + H2O
