3. (a) Beryl (Be3Al2S16018) and Wallastonite (Ca3Si309) are both ring silicates. Using tetrahedral representations, draw the structures of [S16018]12- and [Si30,]6-. (4 marks) (b) Talc is a clay mineral with the chemical formula Mg3Si4010(OH)2. It contains a two dimensional silicate sheet. Using tetrahedral representations, draw the structure of talc. You are only required to draw the silicate structure (i.e. connections of Si and O). What is the repeating unit of this structure? (3 marks) (c) Explain why SiCl4 reacts with water but CCl4 does not. (4 marks)
