Do ionic bonds dissolve in methanol

Though ethanol is fairly polar for a covalent compound, it's nowhere near as polar as water is. That said, ionic compounds are more soluble in ethanol than in more non polar solvents. You can get a little bit of sodium chloride to dissolve in ethanol, but basically no NaCl will dissolve in benzene.

Ithink 2 is the correct

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.
