Answer 1

Answer: 2SO₂(g) + O₂(g) +2H₂O(l)-------> 2 H₂SO₄(aq)

Step 1: Explanation

Steps to balance the chemical reaction

1. Write down your given equation.
2. Write down the number of atoms per element.
3. Save hydrogen and oxygen for last,
4. Start with single elements.
5. Use a coefficient to balance the single carbon atom.
6. Balance the hydrogen atoms next and finally balance oxygen at last.

Sulfur dioxide react with oxygen and water to produce Sulfuric acid . This is a synthesis type of reaction

The unbalanced chemical equation is

SO₂(g) + O₂(g) +H₂O(l)-------> H₂SO₄(aq)

Just multiply SO_2, H₂O and  H₂SO₄ by 2

Step 2: The complete balanced   reaction is

2SO₂(g) + O₂(g) +2H₂O(l)-------> 2 H₂SO₄(aq)

Step 3: check whether reaction is balanced or not

Left side element: S=2, H=4, O=8

Right side element:S=2, H=4, O=8

since the element on both side of compounds are same hence the reaction is balanced.
