Answer 2

Answer:

2

Balanced chemical equation:

• The chemical equation written by balancing total number of atoms of each element in reactants and products
• It is more informative than the unbalanced chemical equation.
• It is based on the law of conservation of mass & Dalton’s atomic theory.

The balanced chemical equation is as follows:

$\sf{2NaOH+{H_2}S{O_4}}$ → $\sf{{Na_2}S{O_ 4}+2{H_2}O.}$

Thus, Two molecules of $\sf{H_2{O}}$ are needed to balance the given reaction.
