2 answers:
Answer : Yes, the given chemical reaction is balanced equation.
Explanation :
Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.
The given chemical reaction is,
In this reaction, there are 2 atoms of sodium, 4 atoms of hydrogen and 2 atoms of oxygen are present on both side of the reaction. So,
This chemical reaction is a balanced reaction because in this reaction, the number of atoms of sodium, hydrogen and oxygen are balanced on the side of the reaction.
Hence, yes the given chemical reaction is balanced equation.
