Question
The following chemical reaction takes place in aqueous solution:FeCl2(aq)+Na2S(aq)→FeS(s)+2NaCl(aq)Write the net ionic equation for this reaction.
Solution 1
Sure, here are the steps to write the net ionic equation for the given reaction:
Step 1: Write the balanced molecular equation: FeCl2(aq) + Na2S(aq) → FeS(s) + 2NaCl(aq)
Step 2: Write the ionic equation showing all ions: Fe2+(aq) + 2Cl-(aq) + 2Na+(aq) + S2-(aq) → FeS(s) + 2Na+(aq) + 2Cl-(aq)
Step 3: Identify and cancel out the spectator ions. These are ions that appear on both sides of the ionic equation. In this case, the spectator ions are 2Na+(aq) and 2Cl-(aq).
Step 4: Write the net ionic equation, excluding the spectator ions: Fe2+(aq) + S2-(aq) → FeS(s)
So, the net ionic equation for the reaction is Fe2+(aq) + S2-(aq) → FeS(s).
Solution 2
Sure, here are the steps to write the net ionic equation for the given reaction:
Step 1: Write the balanced molecular equation: FeCl2(aq) + Na2S(aq) → FeS(s) + 2NaCl(aq)
Step 2: Write the ionic equation showing all ions: Fe2+(aq) + 2Cl-(aq) + 2Na+(aq) + S2-(aq) → FeS(s) + 2Na+(aq) + 2Cl-(aq)
Step 3: Identify and cancel out the spectator ions. These are ions that appear on both sides of the ionic equation. In this case, the spectator ions are 2Na+(aq) and 2Cl-(aq).
Step 4: Write the net ionic equation, excluding the spectator ions: Fe2+(aq) + S2-(aq) → FeS(s)
So, the net ionic equation for the reaction is Fe2+(aq) + S2-(aq) → FeS(s).
Solution 3
Sure, here are the steps to write the net ionic equation for the given reaction:
Step 1: Write the balanced molecular equation: FeCl2(aq) + Na2S(aq) → FeS(s) + 2NaCl(aq)
Step 2: Write the ionic equation showing the ions in the solution: Fe2+(aq) + 2Cl-(aq) + 2Na+(aq) + S2-(aq) → FeS(s) + 2Na+(aq) + 2Cl-(aq)
Step 3: Identify and cancel out the spectator ions. These are ions that appear on both sides of the ionic equation. In this case, the spectator ions are 2Na+(aq) and 2Cl-(aq).
Step 4: Write the net ionic equation, which includes only the ions and molecules that are involved in the reaction: Fe2+(aq) + S2-(aq) → FeS(s)
So, the net ionic equation for the reaction is Fe2+(aq) + S2-(aq) → FeS(s).
