Question

Column-I	Column-II
(A) Carbonate	(P) Siderite
(B) Sulphide	(Q) Malachite
(C) Hydroxide	(R) Bauxite
(D) Oxide	(S) Calamine
	(T) Argentite
	(U) Iron pyrite

Which of the following option has the correct combination considering column-I and column-II.

• A. A,T
• B. B,Q
• C. C,P
• D. D,R

Answer 1

The correct option is D D,R

$\left(P\right)\text{Siderite}\to FeC{O}_3\left(Q\right)\text{Malachite}\to CuC{O}_3.Cu\left(OH{)}_2\right(R)\text{Bauxite}\to A{l}_2{O}_3.x{H}_{2}O\text{or}Al{O}_x(OH{)}_{3–2x}\left(S\right)\text{Calamine}\to ZnC{O}_3\left(T\right)\text{Argentite}\to A{g}_{2}S\left(U\right)\text{Iron pyrite}\to Fe{S}_2$

$A\to \left(P\right)\left(Q\right)\left(S\right),B\to \left(T\right)\left(U\right),C\to \left(Q\right)\left(R\right),D\to \left(R\right)$
