1. lonic compounds ternd to be more flammable than covalent
2. Covalent compounds are soft and flexible.
3. lonic compounds are usually insoluble in water
4. lonic compounds conduct electricity in a solution
5. Covalent compounds generally have higher melting and boiling
Answer:
True or False:
1. False
2. False
3. False
4. True
5. False
Explanation:
True or False:
1. False - Ionic compounds tend to have high melting and boiling points, but their flammability depends on the specific compound.
2. False - Covalent compounds can vary in their physical properties, but they are generally not as soft and flexible as ionic compounds.
3. False - Ionic compounds are usually soluble in water due to the attraction between the ions and the polar water molecules.
4. True - Ionic compounds can conduct electricity when dissolved in water or in a molten state due to the movement of ions.
5. False - Ionic compounds generally have higher melting and boiling points compared to covalent compounds due to the strong electrostatic forces between ions.
