molecular and net ionic equations for FeCl3 + Na2S
2FeCl3(aq) + 3Na2S(aq) ==> Fe2S3(s) + 6NaCl(aq)
2Fe^3+(aq) + 3S^2-(aq) ==> Fe2S3(s)
FeCl3 + Na2S --> FeS + 2NaCl
Molecular equation:
Iron(III) chloride + Sodium sulfide --> Iron(II) sulfide + Sodium chloride
Net ionic equation:
Fe3+ + 3Cl- + 2Na+ + S2- --> FeS + 3Na+ + 3Cl-
To write the molecular and net ionic equations for the reaction between FeCl3 (iron(III) chloride) and Na2S (sodium sulfide), we need to first determine the products of the reaction.
FeCl3 is an ionic compound that dissociates completely in water, producing Fe3+ ions and Cl- ions:
FeCl3(s) → Fe3+(aq) + 3 Cl-(aq)
Na2S is also an ionic compound that dissociates in water, forming Na+ ions and S2- ions:
Na2S(s) → 2 Na+(aq) + S2-(aq)
Now, let's combine the ions to find the products:
Fe3+(aq) + 3 Cl-(aq) + 2 Na+(aq) + S2-(aq) → Fe3+(aq) + 2 Na+(aq) + 3 Cl-(aq) + S2-(aq)
In this reaction, Fe3+ and Cl- ions remain unchanged on both sides of the equation, so they are spectator ions. We can cancel them out to obtain the net ionic equation:
2 Na+(aq) + S2-(aq) → 2 Na+(aq) + S2-(aq)
The net ionic equation simplifies to:
S2-(aq) → S2-(aq)
Therefore, the net ionic equation for the reaction between FeCl3 and Na2S is just the sulfide ions (S2-) remaining the same on both sides.
To write the molecular and net ionic equations for the reaction between FeCl3 (iron (III) chloride) and Na2S (sodium sulfide), we first need to know the formulas of the products.
The formula for iron (III) chloride is FeCl3, and the formula for sodium sulfide is Na2S.
Now, let's break down the reaction and write the molecular equation:
FeCl3 + Na2S → FeS + NaCl
In the molecular equation, we simply write the formulas of the reactants and products, separated by an arrow. However, this equation does not accurately represent the actual species that are involved in the reaction. To obtain the net ionic equation, we need to consider the substances that ionize in the solution.
In this reaction, both FeCl3 and Na2S are ionic compounds that dissolve in water to form ions:
FeCl3 (s) → Fe^3+ (aq) + 3Cl^- (aq)
Na2S (s) → 2Na^+ (aq) + S^2- (aq)
Now we can write the balanced net ionic equation by focusing only on the ions involved in the reaction:
Fe^3+ (aq) + 3Cl^- (aq) + 2Na^+ (aq) + S^2- (aq) → FeS (s) + 3Na^+ (aq) + 3Cl^- (aq)
In the net ionic equation, we only include the ions that participate in the reaction, represented as formulas with their respective charges. It shows the overall reaction without spectator ions (those that do not undergo any chemical change).
So, the molecular equation for the reaction between FeCl3 and Na2S is FeCl3 + Na2S → FeS + NaCl, and the net ionic equation is Fe^3+ (aq) + 3Cl^- (aq) + 2Na^+ (aq) + S^2- (aq) → FeS (s) + 3Na^+ (aq) + 3Cl^- (aq).
