2. Aqueous barium nitrate reacts with sulfuric acid to yield a barium sulfate precipitate and nitric acid.
3. Silver nitrate reacts in solution with potassium chromate to yield a silver chromate precipitate and soluble potassium nitrate.
4. Solid calcium carbonate reacts with hydrochloric acid to yield aqueous calcium chloride, carbon dioxide gas, and liquid water
5. Aqueous zinc chloride reacts with dihydrogen monosulfide gas to yield a zinc sulfide precipitate and hydrochloric acid.
6. Magnesium nitrate reacts in solution with potassium hydroxide to yield a magnesium hydroxide precipitate and soluble potassium nitrate
7. Solid aluminum hydroxide reacts with nitric acid to yield soluble aluminum nitrate and liquid water
8. Aqueous lead (IV) nitrate reacts with aqueous sodium sulfate to yield a lead (IV) sulfate precipitate and soluble sodium nitrate
