8. you can pour water into a glass made of silicon dioxide, sio₂(s). explain why you would never see the…

Brief Explanations:

Silicon dioxide ($SiO_2$) is a covalent - network solid. It has a very strong and rigid three - dimensional network of covalent bonds. Water is a polar solvent. Covalent - network solids like $SiO_2$ do not dissolve in water because the energy required to break the covalent bonds in the solid is much greater than the energy released when the solid interacts with water molecules. So, $SiO_2$ does not exist as an aqueous solution, and we never see $SiO_2(aq)$.

Answer:

Silicon dioxide is a covalent - network solid that does not dissolve in water due to the high energy needed to break its covalent bonds, so we don't see $SiO_2(aq)$.
