Question

Balance - Na2CO3+H2SO4 - Na2SO4 + CO2+ H20

Answer 1

the equation is already balanced

Answer 2

Explanation:

The given equation is :

$Na_2CO_3+H_2SO_4\rightarrow Na_2SO_4+CO_2+H_2O$

In this equation, the element that are used are, Sodium, carbon, oxygen, hydrogen, sulphur.

For a balanced chemical equation, the number of atoms on the left hand side must be same as number of element in right hand side.

In LHS,

Sodium = 2 atoms

Carbon = 1 atom

Oxygen = 3 + 4 = 7 atoms

Hydrogen = 2 atoms

Sulphur = 1

In RHS,

Sodium = 2 atoms

Carbon = 1 atom

Oxygen = 4 + 2 + 1 = 7 atoms

Hydrogen = 2 atoms

Sulphur = 1

Hence, the equation is balanced.
