Why is SiO2 a solid while CO2 is a gas?

However as SiO2(g) condenses into solid SiO2 and you break apart the solid SiO2, you won''t get the "same" SiO2(g) molecules. The Si and O lose their molecular associativity in the solid. $endgroup$ – MaxW Mar 2 ''17 at 18:13

SiO2 + H2O----------------> ? | Yahoo Answers

 · (SiO2 is the primary component of sand) There are specific conditions that it can react very slightly in and that goes the route of: SiO2 + H2O --> H2SiO3 But H2SiO3 is so unstable it''s not funny. Since silicon is in the same family as carbon it reacts similar.
