Answer 1

Answer:

Word equation: Iron (II) sulfide + Hydrochloric acid → Iron (II) chloride + Hydrogen sulfide

Type of Chemical Reaction: For this reaction we have a double replacement reaction.

Balancing Strategies: In this double displacement reaction the Fe and H atoms are switching places. In order to balance the reaction, count the atoms on each side of the equation.

We need to double the number of H and Cl atoms on the reactant side to balance the equation.

Put a "2" in front of the HCl on the reactant side of the equation.

FeS + 2HCl = FeCl2 + H2S
