Best answer

Answer: The reaction is not balanced; the balanced equation is \(\mathrm{2NaOH + H_2SO_4 \rightarrow Na_2SO_4 + 2H_2O}\).

Counting the atoms in the printed equation:

ElementsReactants (left)Products (right)
Na22
O65
H42
S11

The number of oxygen and hydrogen atoms is not the same on the two sides, so the equation is not balanced. Writing 2H2O on the right makes O = 4 + 2 = 6 and H = 4 on both sides:

\[\mathrm{2NaOH + H_2SO_4 \rightarrow Na_2SO_4 + 2H_2O}\]
