Match the list : List - I Ores Name List - II Correct Formula (P) Copper pyrite (1) FeCO 3 ​ (Q) Chalcocite (2) PbCO 3 ​ (R) Cerrusite (3) CuFeS 2 ​ (S) Siderite (4) Cu 2 ​ S

TestHub · Accepted Answer

Copper pyrite has the chemical formula CuFeS₂ which corresponds to (3). Chalcocite (copper glance) has the chemical formula Cu₂S, corresponding to (4). Cerussite is a lead carbonate mineral with the formula PbCO₃, matching (2). Siderite is an iron carbonate mineral with the formula FeCO₃, matching (1). Combining these gives the correct matching sequence: P → 3; Q → 4; R → 2; S → 1. Therefore, the correct option is (C).

List - I Ores Name	List - II Correct Formula
(P) Copper pyrite	(1) $FeCO_{3}$
(Q) Chalcocite	(2) $PbCO_{3}$
(R) Cerrusite	(3) $CuFeS_{2}$
(S) Siderite	(4) $Cu_{2} S$
