Ionic compunds are able to conduct electricity when molten/in solution, but not when they are solid

Answer from: andrealfar1010

Option (1) is the correct answer.

Explanation:

An ionic compound is the compound which is composed of oppositely charged ions.

When an ionic compound is in a solid state, then oppositely charged ions are held together by strong electrostatic force of attraction. To break is force of attraction, high energy is required. That is why, ionic compounds do not conduct electricity as a solid.

Whereas in melted state, the ions are less tightly held and as a result they can move easily from one place to another. Also in melted state, ionic compounds act as strong electrolyte. Hence, they are able to conduct electricity.

On the other hand, molecular compounds are poor conductors of electricity and non-metals do not conduct electricity. Whereas a metal is a good conductor of electricity even in its solid state.

Thus, we can conclude that a substance that does not conduct electricity as a solid but does conduct electricity when melted is most likely classified as an ionic compound.

Answerd. may include all of these are many definitions of bases: the brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.

Atp, shorthand for adenosine triphosphate, is the standard molecule for cellular enger in the human body. all motion and metabolic processes within the body begins with energy that is released from atp, as its phosphate bonds are broken in cells through a process called hydrolysis.

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!
