Solution

$C O_{2}$ consists of individual molecules with one central carbon atom double bonded to two oxygen atoms. Silicon does not form double bonds with oxygen. $C O_{2}$ is gas but $S i O_{2}$ is solid because the $S i O_{2}$ is in giant molecular structure but the $C O_{2}$ is simple molecular structure.Because of this reason $C O_{2}$ is gas but $S i O_{2}$ is solid.
