These are chemical reactions showing the conversion of elements and compounds:

1) Iron (Fe) is oxidized to form Iron(III) oxide (Fe₂O₃), which then reacts with hydrochloric acid to form Iron(III) chloride (FeCl₃), and finally forms Iron(III) hydroxide (Fe(OH)₃) in a precipitation reaction.

2) Aluminum (Al) reacts with chlorine gas to form Aluminum chloride (AlCl₃), which then reacts with water to form Aluminum hydroxide (Al(OH)₃), and finally dehydrates to form Aluminum oxide (Al₂O₃).

3) Sulfur (S) undergoes oxidation to form Sulfur dioxide (SO₂), which further reacts with oxygen to form Sulfur trioxide (SO₃), then reacts with water to form Sulfuric acid (H₂SO₄), and finally reacts with Barium chloride to form Barium sulfate (BaSO₄) in a precipitation reaction.
