\[\ce{NaOH + H2SO4 -> Na2SO4 + H2O}\]
Advertisements
Solution
Step 1: Write the chemical equation
\[\ce{NaOH + H2SO4 -> Na2SO4 + H2O}\]
Step 2: Compare the number of atoms of each element on each side.
| Elements | Number of atoms on the reactant side | Number of atoms on the product side |
| Na | 1 | 2 |
| O | 5 | 5 |
| H | 3 | 2 |
| S | 1 | 1 |
Step 3: Start balancing and write the balanced equation.
| Elements | Number of atoms on the reactant side | Number of atoms on the product side |
| Na | 2 | 2 |
| O | 6 | 6 |
| H | 4 | 4 |
| S | 1 | 1 |
