Question

Match the following

Ores		Composition
A	Calamine	i	$CuFeS _{2}$
B	Chalcopyrites	ii	$ZnCO _{3}$
C	Bauxite	iii	$Fe _{2} O _{3}$
D	Haematite	iv	$Al _{2} O _{3} 2 H _{2} O$

Tlie correct match is

• A. A - (II) ,B - (I) , C - (IV) , D -(III)
• B. A - (I) ,B - (III) , C - (IV) , D -(II)
• C. A - (III) ,B - (I) , C - (II) , D -(IV)
• D. A - (I) ,B - (III) , C - (II) , D -(IV)

Answer 1

Answer: (A)

$\because$ Formula of given ores are as follows :
(A) Calamine $= ZnCO _{3}$
(B) Chalcopyrite $=C u F e S_{2}$
(C) Bauxite $= Al _{2} O _{3} \cdot 2 H _{2} O$
(D) Haematite $= Fe _{2} O _{3}$
