Question

Hydrogen sulfide gas H2S and aqueous iron(II) chloride are formed by the reaction of aqueous hydrochloric acid HCl and solid iron(II) sulfide . Write a balanced chemical equation for this reaction

Answer 1

Answer:

The balanced chemical equation for this reaction is:

2HCl (aq) + FeS (s) -----> FeCl2 (aq) + H2S (g)

Explanation:

Answer 2

Answer:

$2HCl(aq.)+FeS(s)\rightarrow H_{2}S(g)+FeCl_{2}(aq.)$

Explanation:

Unbalanced equation: $HCl(aq.)+FeS(s)\rightarrow H_{2}S(g)+FeCl_{2}(aq.)$

Balance Cl: $2HCl(aq.)+FeS(s)\rightarrow H_{2}S(g)+FeCl_{2}(aq.)$

We can see both side of equation contains two H atoms, two Cl atoms, one Fe atom and one S atom.

Therefore it is a balanced equation.

Balanced equation: $2HCl(aq.)+FeS(s)\rightarrow H_{2}S(g)+FeCl_{2}(aq.)$
