Question

3. What happens when sodium chloride melts?
A Covalent bonds in a giant lattice are broken.
B Electrons are released from atoms.
C Electrostatic forces of attraction between ions are overcome.
D Molecules are separated into ions.

Answer 1

When it melts, sodium chloride undergoes electrolysis, which involves conduction of electricity because of the movement and discharge of the ions. In the process, sodium and chlorine are produced. This is a chemical change rather than a physical process.

Answer 2

Answer:

molecules are seperated into ions
