Ionic molecules have higher boiling point than covalent molecules.
So that leaves Na2SO4 and NaCl.
The ionic molecule with higher charge will have higher boiling point.
Na2SO4 have ions with charge +-2.
NaCl have ions with charge +-1.
So the answer is C.
The answer is the third one because density is mass divided by volume so 80 divided by 10 is 8
Answer:
A and B is the answer as there structure change
A. The bonds between the individual monomers of a polymer are broken by the addition of water molecules.
