Answer
- 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.
