Match the entries of column I with appropriate entires of column II Each entry in column I may have one or more than one corret option from column II if the correct matches are A-p,s, B-r,C-p,q,D-s then the correctly bubbled `4xx4` matrix should be as follows:
`{:(,"column I" ,, "column II "),((A) ,"Metal which reacts with dilute acids to give H_(2) gas" , (p), "zinc"),((B), "Metal whose container can be used to store conc HNO_(3)", (q), "silver"),((C ) ,"Metal which is used as an electrode in daniell cell" , (r),"Aluminium"),((D),"Metal which does not react with dilute acids to give H_(2) gas" , (s),"copper " ):}`

Answer

To solve the problem, we need to match the entries from Column I with the appropriate entries from Column II based on the descriptions provided. Let's go through each entry step by step.

### Step-by-Step Solution:

1. **Entry A: "Metal which reacts with dilute acids to give H₂ gas"**
- Metals that react with dilute acids to produce hydrogen gas (H₂) are those that are more reactive than hydrogen in the reactivity series.
- The metals that fit this description include **Zinc (p)** and **Aluminum (r)**.
- **Match**: A → p, r

2. **Entry B: "Metal whose container can be used to store concentrated HNO₃"**
- To store concentrated nitric acid (HNO₃), the metal must be less reactive than hydrogen, meaning it should not react with HNO₃.
- **Silver (q)** and **Copper (s)** are suitable metals for this purpose.
- **Match**: B → q, s

3. **Entry C: "Metal which is used as an electrode in Daniell cell"**
- The Daniell cell uses **Zinc (p)** as the anode and **Copper (s)** as the cathode.
- **Match**: C → p, s

4. **Entry D: "Metal which does not react with dilute acids to give H₂ gas"**
- Metals that do not react with dilute acids include **Copper (s)** and **Silver (q)**.
- **Match**: D → q, s

### Final Matches:
- A → p, r
- B → q, s
- C → p, s
- D → q, s

### Summary of Correct Matches:
- A: p, r
- B: q, s
- C: p, s
- D: q, s

### Correctly bubbled matrix:
- The correctly bubbled `4xx4` matrix should be:
- A → p, r
- B → q, s
- C → p, s
- D → q, s
