Solution

(A) Kernite-(II) Boron

  1. The scientific name for the boron mineral kernite is hydrated sodium borate hydroxide, and its chemical formula is Na2B4O6(OH)2.3H2O
  2. is a mineral that is found in sedimentary deposits made of water-soluble mineral sediments that crystallize and concentrate after evaporation.
  3. It typically occurs in arid regions.

(B) Cassiterite-(I) Tin

  1. The primary tin ore is cassiterite, commonly referred to as tinstone, which is a heavy, metallic hard tin dioxide (SnO2).
  2. When cassiterite is pure, it is colorless, but when iron impurities are added, it turns brown or black.
  3. The most significant tin ore is cassiterite, however, it is only found in significant quantities in a few places.

(C) Calamine-(IV) Zinc

  1. Calamine mineral's chemical formula is Zn4Si2O7(OH)2H2O
  2. Specifically, this mineral is utilized to extract zinc.
  3. Typically, it is rounded and crystalline, and it is dark brown or grey in color.

(D) Cryolite-(v) Fluorine

  1. Cryolite is a mineral with the chemical formula Na3AlF6 and the chemical name sodium hexafluoroaluminate.
  2. a white or colorless mineral made of sodium and aluminum fluorides.
  3. It is an ore used to extract fluorine from it.

Final answer:
