Molecular and Ionic Equations for the Reaction of Sulfuric Acid with Zinc, Iron, and Copper

Molecular Equation: The molecular equation for the reaction of sulfuric acid with zinc, iron, and copper can be represented as follows:

1. Sulfuric acid with zinc: - Sulfuric acid: H2SO4 - Zinc: Zn - Molecular equation: H2SO4 + Zn → ZnSO4 + H2.

2. Sulfuric acid with iron: - Sulfuric acid: H2SO4 - Iron: Fe - Molecular equation: H2SO4 + Fe → FeSO4 + H2.

3. Sulfuric acid with copper: - Sulfuric acid: H2SO4 - Copper: Cu - Molecular equation: H2SO4 + Cu → CuSO4 + H2.

Ionic Equation: The ionic equations for the reactions can be represented as follows:

1. Sulfuric acid with zinc: - Ionic equation: 2H⁺ + SO4²⁻ + Zn → Zn²⁺ + SO4²⁻ + H2.

2. Sulfuric acid with iron: - Ionic equation: 2H⁺ + SO4²⁻ + Fe → Fe²⁺ + SO4²⁻ + H2.

3. Sulfuric acid with copper: - Ionic equation: 2H⁺ + SO4²⁻ + Cu → Cu²⁺ + SO4²⁻ + H2.

These equations represent the chemical reactions of sulfuric acid with zinc, iron, and copper in both molecular and ionic forms.
