Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Consider the following silicate minerals. Sepiolite → ${\mathrm{Mg}}_4{\mathrm{Si}}_6{\mathrm{O}}_{15}(\mathrm{OH}{)}_2\cdot 6{\mathrm{H}}_2\mathrm{O}$ Pezzottaite → Cs( ${\mathrm{Be}}_2{\mathrm{Li}}_2){\mathrm{Al}}_2{\mathrm{Si}}_6{\mathrm{O}}_{18}$ Glaucophane → ${\mathrm{Na}}_2{\mathrm{Mg}}_3{\mathrm{Al}}_2{\mathrm{Si}}_8{\mathrm{O}}_{22}(\mathrm{OH}{)}_2$ Tanzanite → ${\mathrm{Ca}}_2{\mathrm{Al}}_3\mathrm{O}\left({\mathrm{SiO}}_4\right)\left({\mathrm{Si}}_2{\mathrm{O}}_7\right)(\mathrm{OH})$
