So,
Ionic compounds are compounds composed of ions. The following are soluble ionic compounds (they dissolve in water):
NaCl(s) --> Na⁺(aq) + Cl⁻(aq)
NaOH(s) --> Na⁺(aq) + OH⁻(aq)
The following are insoluble ionic compounds (they have low solubilities):
Al₂O₃ --> 2Al³⁺+3O²⁻
AgCl --> Ag⁺ + Cl⁻
These compounds can only be appreciably separated by melting or by dissolving them in enormous amounts of water (the concentration will still be very low).
Ionic compounds have electrons that are locked in place because of the strong ionic attractions between the ions. A charge is produced by moving electrons. Since the ions in melted ionic compounds are free to move, their electrons are no longer locked, allowing the ionic liquid to conduct electricity.
NaCl(s) --> Na⁺(l) + Cl⁻(l)
The answer is D.
Answer:
Subbituminous coal can form at temperatures as low as 35 to 80 °C (95 to 176 °F) while anthracite requires a temperature of at least 180 to 245 °C (356 to 473 °F).
Sub-types: Cannel coal
Child material class: Lignite
Explanation:
Answer:
The distilled water solution would be hypotonic to your blood cells, so they would gain water, swell, and possibly burst.
I am pretty sure that the statement which is true is A. a molecule having a covalent bond can be ionic. I choose this option because you usually ca see how electons of polyatomic ions are being covalenr and gain or loose ionic electrons in order to accomplish the octet.<span>
