Which of the following compounds would result in an exchange reaction if mixed in an aqueous solution with (NH4)2S?
I don't know what to look for.
Look for the following:
1. formation of an insoluble substance (a precipitate). Do you know the solubility rules?
2. formation of a gas.
3. formation of a weak electrolyte.
4. possibility of an oxidation-reduction reaction.
Here are the solubility rules.
