Supply the correct formulas for each compound and balance the equations: (Don’t forget
which elements are diatomic!!)
11.
copper (I) sulfate + iron → iron (II) sulfate + copper
12.
mercury (II) oxide → mercury + oxygen (diatomic)
13.
calcium hydroxide + carbon dioxide → calcium carbonate + water
14.
iron (II) sulfide + hydrochloric acid → iron (II) chloride + hydrogen sulfide
15. sodium sulfite + sulfuric acid → sodium sulfate + water + sulfur dioxide
16. aluminum + hydrochloric acid → aluminum chloride + hydrogen (diatomic)
17. iron + sulfur → iron (II) sulfide
18. sodium chloride + silver nitrate → sodium nitrate + silver chloride
19. calcium oxide + water → calcium hydroxide
20. aluminum + iron (III) oxide → aluminum oxide + iron
