- This is a precipitation reaction. Products: $FeS$ $2NH_4Cl$ Completed equation: $FeCl_2(aq) + (NH_4)_2S(aq) \lt -- \gt FeS(s) + 2NH_4Cl(aq)$
Work Step by Step
1. Write and analyze the products of the reaction: - Since we have 2 ionic compounds, we will have a double displacement reaction. So, the products are: $FeS$: Which is insoluble in water* $(NH_4)_2Cl_2 --> 2NH_4Cl$: Which is soluble in water* * According to table 3.1 (Page 101). Since we have an insoluble product, there will be precipitation. - This is a precipitation reaction. Since we already have the reactants and the products, the final chemical reaction is: $FeCl_2(aq) + (NH_4)_2S(aq) \lt -- \gt FeS(s) + 2NH_4Cl(aq)$ - The reaction is balanced.
