Answer:
Molecular solids are held together by relatively weak forces, such as dipole–dipole interactions, hydrogen bonds, and London dispersion forces.
Answer:
True
Explanation:
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate.
Open- end credit can be used for anything up to a certain limit but nothing can be purchased after they’ve reached the limit
Answer:
Sodium fluoride and calcium iodide are ionic and carbon disulfide covalent.
Explanation:
Hello,
Since both calcium iodide and sodium fluoride are ionic compounds, one could identify that in comparison with carbon disulfide which is covalent:
- they've got both a cation and an anion.
- they are crystalline solids.
- they've got higher fusion points due to stronger electrostatic attractive forces.
- they don't conduce the electricity when solid but do it when liquid or in aqueous phase solutions.
Unlike sodium fluoride and calcium iodide, carbon disulfide:
- doesn't conduct the electricity.
- doesn't form charged particles in aqueous solutions.
- it tends to be liquid or gas due to weak intermolecular forces.
Best regards.
