Final answer:
The balanced chemical equation for the reaction of sulfur trioxide (SO₃) with water is: SO₃ + H₂O → H₂SO₄. When sulfur trioxide reacts with water, it forms sulfuric acid (H₂SO₄). This reaction is commonly known as the hydration of sulfur trioxide. The correct option is a.
Step-by-step explanation:
The balanced chemical equation for the reaction of sulfur trioxide (SO₃) with water is:
SO₃ + H₂O → H₂SO₄
When sulfur trioxide reacts with water, it forms sulfuric acid (H₂SO₄). This reaction is commonly known as the hydration of sulfur trioxide.
The equation shows that one molecule of sulfur trioxide reacts with one molecule of water to produce one molecule of sulfuric acid. Option a. is the correct one.
