Example of a three-dimensional silicate is :

Options

  1. AUltramarines
  2. BFeldspars
  3. CZeolites
  4. DAll of these

Correct answer

D. All of these

Step-by-step solution

Three-dimensional silicates are formed by sharing all four oxygen atom of SiO 4 4 - . Ultramarines, feldspars and zeolites are examples of three- dimensional silicates. Molecular formula of ultramarine is Na 8 ( SiAlO 4 ) 6 feldspar is KAlSi 3 O 8 and zeolite is Na 2 Al 2 Si 2 O 8 .   xH 2 O .
