Which additional product balances the reaction [tex]$H_2SO_4 + 2NaOH \rightarrow Na_2SO_4 +$[/tex]?

A. [tex]$2OH$[/tex]
B. [tex]$H_2O_2$[/tex]
C. [tex]$H_3O$[/tex]

Answer :

To determine the additional product that balances the chemical reaction, let's take a look at the reaction:

[tex]\[ H_2SO_4 + 2 \, NaOH \rightarrow Na_2SO_4 + \][/tex]

The products given are:

1. 2 H[tex]\(_2\)[/tex]O
2. 2 OH
3. H[tex]\(_2\)[/tex]O[tex]\(_2\)[/tex]
4. H[tex]\(_3\)[/tex]O

The reaction is between sulfuric acid (H[tex]\(_2\)[/tex]SO[tex]\(_4\)[/tex]) and sodium hydroxide (NaOH) to form sodium sulfate (Na[tex]\(_2\)[/tex]SO[tex]\(_4\)[/tex]) and water (H[tex]\(_2\)[/tex]O).

### Step-by-step balancing:

1. Balance the Sodium (Na) atoms:
- On the left side, you have 2 Na from 2 NaOH.
- On the right side, to balance the sodium, you have 2 Na in Na[tex]\(_2\)[/tex]SO[tex]\(_4\)[/tex].

2. Balance the Sulfate (SO[tex]\(_4\)[/tex]) group:
- On the left side, there is 1 [tex]\(SO_4\)[/tex] in H[tex]\(_2\)[/tex]SO[tex]\(_4\)[/tex].
- On the right side, there is 1 [tex]\(SO_4\)[/tex] in Na[tex]\(_2\)[/tex]SO[tex]\(_4\)[/tex].

3. Balance the Hydrogen (H) atoms:
- On the left side, there are 2 H from H[tex]\(_2\)[/tex]SO[tex]\(_4\)[/tex] and 2 \times 1 H from 2 NaOH, totaling 4 H atoms.
- On the right side, placing 2 H[tex]\(_2\)[/tex]O gives 4 H atoms (2 \times 2 H in H[tex]\(_2\)[/tex]O).

4. Balance the Oxygen (O) atoms:
- On the left side, there are 4 O from H[tex]\(_2\)[/tex]SO[tex]\(_4\)[/tex] and 2 \times 1 O from 2 NaOH, totaling 6 O atoms.
- On the right side, there are 4 O in Na[tex]\(_2\)[/tex]SO[tex]\(_4\)[/tex] and 2 \times 1 O in 2 H[tex]\(_2\)[/tex]O, also totaling 6 O atoms.

After checking all the elements, you can see that the entire equation is balanced with the addition of 2 H[tex]\(_2\)[/tex]O. Therefore, the additional product that balances the reaction is:

[tex]\[ \boxed{2 \, H_2O} \][/tex]
