Two dimensional sheet silicates: In such silicates, three oxygen atoms of each tetrahedral are shared with adjacent \(SiO_4^{4-}\) tetrahedral, such sharing forms two dimensional sheet structure with general formula \((Si_2O_5)_n^{2n-}\)
Ex. Talc \(Mg(Si_2O_5)_2Mg(OH)_2\)
The structure of silicates has been found with the help of X-ray diffraction techniques.
Hence, The correct Answer is option B sheet silicate.
The number of oxygen atoms present in chemical formula of fuming sulphuric acid is _______.
