Question

Classify this equation: FeS + HCl → H2S + FeCl2

Answer 1

FeS + HCl → H2S + FeCl2

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.

When balancing chemical equations our goal is to have the same number of each type of atom on both sides of the equation.

Only change the coefficients (these are the numbers in front substances).

Coefficients are the numbers in front of the molecule.

Never change the subscripts (the small numbers after elements).

Coefficients are the numbers in front of the molecule.
