Answer 7

Ionic bond is a strong electrostatic force of attraction between oppositely charged ions, a number of oppositely charged ions are held to gether by strong attraction, which is why ionic compounds have very high melting and boiling points. A covalent bond is formed by the sharing of electons between the atoms. Very weak forces exist between covalent molecules, that is why covalent compounds have low melting and boiling points.

Answer 8

wow dude... just stop being smart XD

Answer 9

can you help me with 2 more questions? @Xbeast

Answer 10

Im sorry for being smart, I guess? uh sure, gonna have to give me a minute to reply because of precalc but yea.

Answer 11

thx you're awesomeeeee :D

Answer 12

3.In order to conduct an electrical current, a substance must have charged particles (ions or electrons) that are free-moving (able to move about throughout the sample).


a.Why do you think ionic compounds are not able to conduct electricity as solids, even though they can as liquids and in solution?


b.Based on your research and observations, why do you think pure (distilled) water does not conduct electricity but tap water usually does?

Answer 13

A. Ionic compounds can't move in their solid state because the electrons also can't move freely. Solids are rigid structures that are caused by bond formation. If electrons can't move, there will be no current for electricity to pass through. Electrons from opposite poles need to have a solution to move electrons from anode to the cathode.
B. Pure water only contains water molecules, meaning no ions, electrons, or charges. Tap water contains impurities or minerals (salts) that dissociate into ions and move freely in the solution, these free moving ions help to conduct electricity.

thank you so much!!!
