(a)
Interpretation:
The balanced chemical equation needs to be determined for a double replacement reaction that occurs in an aqueous solution when zinc sulfide is added to sulfuric acid.
Concept Introduction :
An exchange of positive ions between the two aqueous solutions AB + CD which results in CB + AD is the general form of the double replacement reaction.
