CO2 is gas while SiO3 is solid at room temperature.
Correct answer: B. CO3 is an independent molecule while Si02 has network covalent structure
- A. carbon is non-metal while silicon is semi-metal
- B. CO3 is an independent molecule while Si02 has network covalent structure
- C. CO2 forms multiple bond while silicon does not form multiple bonds
- D. Silicon has all sigma bonds.
Explanation
While all the listed options contain some truths about the differences between CO2 and SiO2, only one accurately explains their contrasting states at room temperature:CO3 is an independent molecule while SiO2 has a network covalent structure.Therefore, the independent molecule structure of CO2 compared to the extensive network covalent structure of SiO2 best explains their different physical states at room temperature.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
