Step 1
Which gas causes acid rain?
Answer
The gas that causes acid rain is sulfur dioxide (SO₂). When sulfur dioxide is released into the atmosphere, it reacts with water vapor and oxygen, forming sulfuric acid (H₂SO₄). This acid then falls to the ground as acid rain, leading to environmental damage and various negative effects on ecosystems.
