The reaction you've written appears to be a neutralization reaction between phosphoric acid (H₃PO₄) and calcium hydroxide (Ca(OH)₂). The products of this reaction include calcium phosphate (Ca₃(PO₄)₂) and water (H₂O).
To balance the equation, let's first write the unbalanced form:
\[
\text{H}_3\text{PO}_4 + \text{Ca(OH)}_2 \rightarrow \text{Ca}_3(\text{PO}_4)_2 + \text{H}_2\text{O}
\]
To balance this reaction, we need to follow these steps:
1. **Identify the number of each type of atom on both sides**.
2. **Balance the calcium (Ca) atoms**: Calcium phosphate has 3 calcium atoms, meaning we need 3 calcium hydroxide molecules on the reactant side.
3. **Balance the phosphate (PO₄) counts**: Calcium phosphate has 2 phosphate groups, thus we need 2 phosphoric acid molecules.
4. **Balance the hydrogen (H) and oxygen (O) atoms**.
The balanced equation would look like this:
\[
2 \text{H}_3\text{PO}_4 + 3 \text{Ca(OH)}_2 \rightarrow \text{Ca}_3(\text{PO}_4)_2 + 6 \text{H}_2\text{O}
\]
**Balanced Reaction**:
\[
2 \text{H}_3\text{PO}_4 + 3 \text{Ca(OH)}_2 \rightarrow \text{Ca}_3(\text{PO}_4)_2 + 6 \text{H}_2\text{O}
\]
### Summary
- 2 molecules of phosphoric acid react with 3 molecules of calcium hydroxide to form 1 molecule of calcium phosphate and 6 molecules of water.
