Question

Match the column (I) and (II) and select the correct answer using the codes given below.

Column-I	Column-II
(a) Argentite	(1) Halide ore of magnesium
(b) Cuprite	(2) Carbonate ore of iron
(c) Siderite	(3) Oxide ore of copper
(d) Carnallite	(4) Sulphide ore of silver

• A. a-4, b-3, c-2, d-1
• B. a-1, b-2, c-3, d-4
• C. a-2, b-3, c-3, d-1
• D. a-3, b-4, c-1, d-2

Answer 1

Answer: (A)

a-4, b-3, c-2, d-1

Argentite = $A{g}_{2}S;$Cuprite = $C{u}_{2}O$;
Siderite = $FeC{O}_3$;
Carnallite =$KCl.MgC{l}_2.6H_{2}O$
