Vedclass · Answer

(A) Carbon dioxide $(CO_2)$ exists as discrete,linear covalent molecules held together by weak van der Waals forces,which makes it a gas at room temperature.In contrast,silica $(SiO_2)$ forms a three-dimensional network structure where each silicon atom is covalently bonded to four oxygen atoms in a tetrahedral arrangement,resulting in a high-melting solid.

Carbon dioxide is a gas while silica is a solid because .......
