To write the balanced chemical equation for the reaction between sulfuric acid (H₂SO₄) and calcium hydroxide (Ca(OH)₂), we start with the reactants and identify the products.
When sulfuric acid reacts with calcium hydroxide, the products formed are calcium sulfate (CaSO₄) and water (H₂O).
The unbalanced equation is:
\[ \text{H}_2\text{SO}_4 + \text{Ca(OH)}_2 \rightarrow \text{CaSO}_4 + \text{H}_2\text{O} \]
Now, let's balance the equation:
- We have 1 sulfur atom and 4 oxygen atoms in sulfuric acid, which matches with calcium sulfate.
- We also balance the calcium and the hydroxide ions.
Balancing the entire equation gives:
\[ \text{H}_2\text{SO}_4 + \text{Ca(OH)}_2 \rightarrow \text{CaSO}_4 + 2\text{H}_2\text{O} \]
Thus, the balanced chemical equation for the reaction is:
\[ \text{H}_2\text{SO}_4 + \text{Ca(OH)}_2 \rightarrow \text{CaSO}_4 + 2\text{H}_2\text{O} \]
