The correct Answer is:
To solve the problem of matching the information in the three columns, we will analyze each reaction, process, and ore step by step. ### Step-by-Step Solution: 1. **Identify the First Reaction: PbS → PbO** - **Process**: This reaction involves the conversion of lead sulfide (PbS) to lead oxide (PbO). The process used for this conversion is known as **roasting**. - **Ore**: The ore used here is **Galena**, which is represented by (Q). - **Combination**: (I) PbS → PbO matches with (i) Roasting and (Q) Galena. 2. **Identify the Second Reaction: CaCO₃ → CaO** - **Process**: This reaction involves the thermal decomposition of calcium carbonate (CaCO₃) to calcium oxide (CaO). The process used for this conversion is called **calcination**. - **Ore**: The ore used here is **Limestone**, represented by (S). - **Combination**: (II) CaCO₃ → CaO matches with (ii) Calcination and (S) Limestone. 3. **Identify the Third Reaction: ZnS → Zn** - **Process**: This reaction involves the conversion of zinc sulfide (ZnS) directly to zinc (Zn) through a process known as **carbon reduction**. - **Ore**: The ore used here is **Zinc Blende**, represented by (P). - **Combination**: (III) ZnS → Zn matches with (iii) Carbon reduction and (P) Zinc Blende. 4. **Identify the Fourth Reaction: CuFeS₂ → Cu** - **Process**: This reaction involves the conversion of copper pyrite (CuFeS₂) to copper (Cu) through a process known as **salt reduction**. - **Ore**: The ore used here is **Pyrite**, represented by (R). - **Combination**: (IV) CuFeS₂ → Cu matches with (iv) Salt reduction and (R) Pyrite. ### Final Combinations: - (I) PbS → PbO matches with (i) Roasting and (Q) Galena. - (II) CaCO₃ → CaO matches with (ii) Calcination and (S) Limestone. - (III) ZnS → Zn matches with (iii) Carbon reduction and (P) Zinc Blende. - (IV) CuFeS₂ → Cu matches with (iv) Salt reduction and (R) Pyrite. ### Summary of Correct Combinations: - (I, i, Q) - (II, ii, S) - (III, iii, P) - (IV, iv, R)
