What type of compound will have a high melting point and conduct electricity?
Ionic compounds will have a high melting point and conduct electricity when melted or dissolved in water due to their ability to form charged ions that can carry electric current.
Which is not a common property of ionic compounds?
The ability to conduct electricity in the solid state is not a common property of ionic compounds, as they typically only conduct electricity when molten or in solution.
What substance has a high melting and boiling point and conducts electricity?
Graphite is an example of a substance that has a high melting and boiling point and can conduct electricity. It has a layered structure that allows for the easy movement of electrons, which is why it can conduct electricity despite being a non-metal.
What substance has a melting point of 1074 K conducts electricity when dissolved in water but does not conduct electricity in the solid phase?
Sodium chloride fits this description. It has a melting point of 1074 K and conducts electricity when dissolved in water as it dissociates into sodium and chloride ions, but does not conduct electricity in the solid state because the ions are not free to move.
Compared with ionic compounds solid molecular compounds generally?
have lower melting and boiling points, exist as discrete molecules, and do not conduct electricity in the solid state.
What is a solid substance that does not dissolve in water does not conduct electricity and does not melt below 1500 C?
One example of a substance fitting this description is diamond. Diamond is a natural crystalline solid that does not dissolve in water, does not conduct electricity, and has a melting point of around 3550°C.

What are the unsual propeties of non metals?
They do not conduct electricity 2.They are not malleable 3.They have low melting and boiling point.4.They are bad conductors of heat.
Does lead conduct electricity when melted?
Yes, lead does conduct electricity when melted. In its molten state, lead becomes a good conductor of electricity due to the free movement of its electrons. This property is why lead is often used in various electrical applications, such as soldering.
Which of these is NOT a characteristic of an ionic compound A. is a solid B. has a low melting point C. is composed of metallic and nonmetallic elements D. when melted will conduct electricity?
B. has a low melting point is NOT a characteristic of an ionic compound. Ionic compounds typically have high melting points due to the strong electrostatic forces between the ions in the crystal lattice.
Why is pure aluminium oxide mixed with cryolite before electrolysis?
Pure aluminium oxide is mixed with cryolite in electrolysis of aluminium because cryolite lowers the melting point of the mixture, making the process more energy-efficient. This allows the aluminium oxide to dissolve in the molten cryolite and conduct electricity more easily, leading to the extraction of aluminium metal from the ore.
