Match list I with list II

List I (Name of ore / mineral) | List II (Chemical formula)
(a) Calamine | (i) ZnS
(b) Malachite | (ii)

FeCO_{3}

ZnCO_{3}

(d) Sphalerite | (iv)

CuCO_{3} \cdot Cu (OH)_{2}

Choose the most appropriate answer from the options given below:

Answer: A → III, B → IV, C → II, D → I

Solution

Calamine is zinc carbonate,

ZnC O_{3}

; malachite is the basic copper carbonate

CuC O_{3} \cdot Cu (OH)_{2}

; siderite is iron(II) carbonate,

FeC O_{3}

; and sphalerite is zinc sulphide,

ZnS

. Thus calamine pairs with

ZnC O_{3}

, malachite with

CuC O_{3} \cdot Cu (OH)_{2}

, siderite with

FeC O_{3}

and sphalerite with

ZnS
