Question

Sulfuric acid is a component of acid rain formed when gaseous sulfur dioxide pollutant reacts with gaseous oxygen and liquid water to form aqueous sulfuric acid. part a write a balanced chemical equation for this reaction. express your answer as a chemical equation. identify all of the phases in your answer.

Answer 1

2SO₂(g) + O₂(g) + 2H₂O(aq) → 2H₂SO₄(aq)

Answer 2

The chemical reaction is :

`2SO_2(g)+O_2(g)+2H_2O(l)\rightarrow 2H_2SO_4(aq)`

Step-by-step explanation:

When sulfur dioxide gas reacts with oxygen gas and liquid water it gives aqueous solution of sulfuric acid.

This is reason behind the acidic nature of the rain water during acid rain.The chemical reaction is given as:

`2SO_2(g)+O_2(g)+2H_2O(l)\rightarrow 2H_2SO_4(aq)`

According to stoichiometry, 2 moles of sulfur dioxide gas reacts with 1 mole of oxygen gas and 2 moles of water to give 2 moles of aqueous sulfuric acid.
