Is the solid state of SiO2 classified as an ionic crystal, a covalent crystal, a molecular crystal, or a metallic crystal? Explain. Solid-state Crystals: The solid state crystals would have a definite arrangement of constituent element with d...
Both CO2 and SiO2 exhibit covalent bonding, so why is CO2 not a covalent-network solid? Which atom is most likely to accept electrons to form an ionic bond? What occurs in an ionic bond? Does oxygen form ionic or covalent bonds?
- The structure of SiO2 is a network solid, which is characterized by strong covalent bonds throughout the entire structure, making it a solid. Conclusion for Statement D: This statement is true. Final ConclusionAfter analyzing all the statements:- Statement A is the only false statement, ...

Where SiO2 has strong covalent bonds between molecules, SO3 only has weak van der waals intermolecular forces holding its molecules together. Since covalent bonds require more energy to overcome than van der waals,SiO2 requires a higher temperature than SO3 to melt, thus SiO2 has a higher meltin...
What are the major intermolecular forces that hold SiO2 together? What is the predominant intermolecular force present in Ar? a) London Dispersion b) Dipole-dipole c) Hydrogen Bonding (a) Identify the intermolecular forces from strongest to weakest and place the following compounds in the appropriat...
