Answer» CORRECT answer is (b) SILICA To explain I would say: Sand is primarily composed of silicon dioxide, also called silica. Silicon tetroxide is not a COMPOUND but an oxo-anion of silicon. Silicon METAL does not form native in nature and feldspar is a mineral ore consisting of several TECTOSILICATE compounds. |
