![**Chemical Reaction Balancing Exercise**
**Question:**
What is the balanced equation for this reaction?
Options:
- a) \( \text{FeCl}_2(aq) + \text{Na}_2\text{S}(aq) \rightarrow \text{FeS}(s) + 2 \text{NaCl}(aq) \) ✔️
- b) \( \text{IrCl}_2(aq) + \text{Na}_2\text{S}(aq) \rightarrow \text{IrS}(s) + 2 \text{NaCl}(aq) \)
- c) \( \text{FeCl}_2(aq) + \text{Na}_2\text{SO}_4(aq) \rightarrow \text{FeSO}_4(aq) + 2 \text{NaCl}(aq) \)
- d) \( \text{FeCl}_3(aq) + \text{Na}_2\text{S}(aq) \rightarrow \text{FeS}(s) + \text{NaCl}(aq) \)
**Answer:**
The balanced equation for this reaction is:
\[ \text{FeCl}_2(aq) + \text{Na}_2\text{S}(aq) \rightarrow \text{FeS}(s) + 2 \text{NaCl}(aq) \]
This indicates a double displacement reaction where iron(II) chloride and sodium sulfide react in aqueous solutions to form solid iron(II) sulfide and sodium chloride.
