Options

A. `{:(A,B,C,D),(4,5,1,3):}`
B. `{:(A,B,C,D),(3,5,1,2):}`
C. `{:(A,B,C,D),(4,3,1,2):}`
D. `{:(A,B,C,D),(3,4,1,2):}`

Answer

To solve the problem of matching the ores with their respective chemical formulas, we can follow these steps:

### Step 1: Identify the Ores and Their Chemical Formulas
We have two lists:
- **List I (Ores)**:
- A) Gypsum
- B) Barytes
- C) Galena
- D) Zinc blende

- **List II (Formulas)**:
- 1) PbS (Lead sulfide)
- 2) ZnS (Zinc sulfide)
- 3) BaSO₄ (Barium sulfate)
- 4) CaSO₄·2H₂O (Gypsum)
- 5) Fe₃O₄ (Iron(II,III) oxide)

### Step 2: Match Each Ore with Its Formula
1. **Gypsum (A)**: Gypsum is known to be calcium sulfate dihydrate, which has the formula **CaSO₄·2H₂O**. This corresponds to option **4**.

2. **Barytes (B)**: Barytes is the ore of barium and is represented by the formula **BaSO₄**. This corresponds to option **3**.

3. **Galena (C)**: Galena is the ore of lead and is represented by the formula **PbS**. This corresponds to option **1**.

4. **Zinc blende (D)**: Zinc blende is the ore of zinc and is represented by the formula **ZnS**. This corresponds to option **2**.

### Step 3: Write the Final Matches
Now, we can summarize the matches:
- A) Gypsum → 4) CaSO₄·2H₂O
- B) Barytes → 3) BaSO₄
- C) Galena → 1) PbS
- D) Zinc blende → 2) ZnS

### Final Answer
The correct matches are:
- A - 4
- B - 3
- C - 1
- D - 2
