- Option B: (b) Zinc + Hydrochloric acid → Zinc chloride + Hydrogen is correct. The correct reaction is Zinc + Hydrochloric acid → Zinc chloride + Hydrogen gas. Though the products are correct,
- Option C: (c) Lead nitrate + Potassium iodide → Lead iodide + Potassium nitrate is correct. The actual reaction is Lead nitrate + Potassium iodide → Lead iodide + Potassium nitrate
- Option D: (d) Magnesium + Nitrogen → Magnesium nitride is correct. This reaction is discussed in the provided content. The correct reaction would be Magnesium + Nitrogen → Magnesium nitride (Mg3N2)
so all options are correct so

Correctly Matched Pairs in Chemical Reactions
The question provides various chemical reactions and asks for the correctly matched pair. Let's analyze each reaction to confirm that all of them are indeed correct.
1. Zinc + Hydrochloric Acid
- Reaction: Zinc + Hydrochloric acid → Zinc chloride + Hydrogen
- Explanation: This is a single displacement reaction where zinc displaces hydrogen from hydrochloric acid, forming zinc chloride and releasing hydrogen gas. This reaction is well-known and commonly demonstrated in chemistry.
2. Lead Nitrate + Potassium Iodide
- Reaction: Lead nitrate + Potassium iodide → Lead iodide + Potassium nitrate
- Explanation: This is a double displacement reaction where lead nitrate and potassium iodide react to form lead iodide (a yellow precipitate) and potassium nitrate. This reaction is also frequently encountered in chemistry.
3. Magnesium + Nitrogen
- Reaction: Magnesium + Nitrogen → Magnesium nitride
- Explanation: In this reaction, magnesium reacts with nitrogen gas to form magnesium nitride. This is a synthesis reaction where two elements combine to form a compound.
Conclusion
- All the reactions provided are correct and accurately represent the chemical processes described.
- Therefore, option 'A' (All of these) is indeed the correct answer, as each reaction is correctly matched.
This thorough analysis confirms that all the reactions are valid, making option 'A' the right choice.
