[tex]\[ 2 \, \text{NaOH} + \text{H}_2\text{SO}_4 \rightarrow \text{Na}_2\text{SO}_4 + \text{H}_2\text{O} \][/tex]

The equation is [tex]$\square$[/tex] because the number of hydrogen atoms and [tex]$\square$[/tex] atoms is [tex]$\square$[/tex] in the reactants and in the products.

The equation is not balanced because the number of hydrogen atoms and oxygen atoms is not equal in the reactants and in the products.

Here's a step-by-step breakdown of how we determine this:

1. Number of Sodium (Na) Atoms:
- In the reactants: There are 2 Na atoms from 2 NaOH.
- In the products: There are 2 Na atoms from Na₂SO₄.
- Sodium atoms are balanced.

2. Number of Hydrogen (H) Atoms:
- In the reactants: There are 2 H atoms from NaOH and 2 H atoms from H₂SO₄, making a total of 4 H atoms.
- In the products: There are 2 H atoms from H₂O.
- Hydrogen atoms are not balanced.

3. Number of Oxygen (O) Atoms:
- In the reactants: There are 2 O atoms from NaOH and 4 O atoms from H₂SO₄, making a total of 6 O atoms.
- In the products: There are 4 O atoms from Na₂SO₄ and 1 O atom from H₂O, making a total of 5 O atoms.
- Oxygen atoms are not balanced.

4. Number of Sulfur (S) Atoms:
- In the reactants: There is 1 S atom from H₂SO₄.
- In the products: There is 1 S atom from Na₂SO₄.
- Sulfur atoms are balanced.

Since the number of hydrogen and oxygen atoms in the reactants and products are not equal, the equation is not balanced.
