AI Generated Solution

To predict the nature of bonding in quartz (SiO₂) and carbon dioxide (CO₂), we can analyze their melting and sublimation points and the types of solids they form. ### Step-by-Step Solution: 1. **Identify the Melting and Sublimation Points**: - The melting point of quartz (SiO₂) is 160 °C. - The sublimation point of carbon dioxide (CO₂) is -79 °C. ...
