Explanation:
Oxidation:
- In the reaction Zn + H2SO4 → ZnSO4 + H2, zinc (Zn) is undergoing oxidation.
- Oxidation refers to the loss of electrons by a substance during a chemical reaction.
- In this reaction, zinc (Zn) is losing electrons to form zinc sulfate (ZnSO4).
Reduction:
- Reduction refers to the gain of electrons by a substance during a chemical reaction.
- In this reaction, hydrogen ions from sulfuric acid (H2SO4) are gaining electrons to form hydrogen gas (H2).
Simple Dissolution:
- Simple dissolution refers to the process of a substance dissolving in a solvent without undergoing a chemical reaction.
- In this reaction, zinc sulfate (ZnSO4) is formed but zinc (Zn) is not simply dissolving in sulfuric acid (H2SO4), it is undergoing a chemical change.
Double Decomposition:
- Double decomposition is a type of chemical reaction where two compounds react to form two different compounds by mutual exchange of ions.
- In the given reaction, there is no exchange of ions between two compounds to form new compounds, so it is not a double decomposition reaction.
Therefore, the correct answer is option 'A' - Oxidation.
