Example of a three-dimensional silicate is :

Options

AUltramarines
BFeldspars
CZeolites
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 ${Na}_{2}{Al}_{2}{Si}_{2}{O}_{8} . {xH}_{2}O$ .
