Final answer:

Sulfur-oxidizing bacteria produce sulfuric acid (H₂SO₄) and sulfur dioxide (SO₂). These processes are also related to the industrial synthesis of sulfuric acid where SO₂ is further oxidized to SO₃ before being converted to H₂SO₄.

Step-by-step explanation:

Sulfur-oxidizing bacteria primarily produce sulfuric acid (H₂SO₄) and sulfur dioxide (SO₂) as part of their metabolic processes. When these bacteria oxidize sulfur compounds, sulfuric acid can be formed as a byproduct. Additionally, sulfur dioxide is an intermediate product in the industrial synthesis of sulfuric acid, where it reacts with oxygen to form sulfur trioxide (SO₃), which is then used to produce sulfuric acid.

The formulas for the compounds mentioned in the question are:

  • Iron (II) sulfate - FeSO₄
  • Boron trifluoride - BF₃
  • Sulfur trioxide (mentioned for context) - SO₃
