EEJ MAIN Chemistry QUESTION #7122
Question 1
Match the ores in List I with their corresponding metals in List II:
  • (I) Siderite - (II) Kaolinite - (III) Malachite - (IV) Calamine
  • (a) Zinc - (b) Copper - (c) Iron - (d) Aluminium
  • (I)-(a); (II)-(b); (III)-(c); (IV)-(d)
  • (I)-(c); (II)-(d); (III)-(b); (IV)-(a)✔️
  • (I)-(c); (II)-(d); (III)-(a); (IV)-(b)
  • (I)-(b); (II)-(c); (III)-(d); (IV)-(a)
Correct Answer Explanation
The correct matching of ores to metals is:
  • Siderite: $FeCO_3$ (Iron)
  • Kaolinite: $Al_2Si_2O_5(OH)_4$ (Aluminium)
  • Malachite: $Cu_2CO_3(OH)_2$ (Copper)
  • Calamine: $ZnCO_3$ (Zinc)
