Question

The crystal structure of NaBr is represented in the diagram above. Which statement correctly compares crystalline NaBr(s) to moiten NaBr(t) in terms of electrical conductivity? Crystalline NaBr contains no freely moving electrons that could conduct an electrical current, whereas electrons can flow freely in molten NaBr, which is a good conductor of electricity Crystalline NaBr and molten NaBr both containions that are held in fixed positions due to strong electrostatic attractions among the ions, making neither a good electrical conductor Crystalline NaBr and molten NaBr both contain Na atoms that transfer electrons to Br atoms in a chemical reaction, thus allowing them both to be good conductors of electricity Crystalline NaBr contains no freely moving electrons to conduct electricity, but molten NaBr is composed of freely moving Nat and Br ions, which allows it to be a good conductor of electricity

Answer 1

Answer A

Crystalline NaCl is solid structure where ions does not dissociate .

Molten NaCl dissociate in to Na + ( aq ) and Cl- ( aq ). Due to dissociation of free ions, there will be conductance in molten NaCl.
