Try a question

Which row correctly pairs a source of atmospheric sulfur dioxide with a balanced equation for its formation?

  1. Sulfur impurities in diesel fuel; 2SO₂ + O₂ → 2SO₃
  2. Combustion of sulfur-containing coal; S + O₂ → SO₂
  3. Heating limestone in a kiln; CaCO₃ → CaO + SO₂
  4. Lightning in air; N₂ + O₂ → 2NO
Answer

B. Combustion of sulfur-containing coal; S + O₂ → SO₂. Sulfur in coal reacts with oxygen during combustion to form SO₂. The equation S + O₂ → SO₂ is balanced.
