Answer:
A. Sucrose
D. Distilled water
Explanation:
Nonconductive substances are those that are covalently bonded. To have a conductive solution we have to have ions in solution, with that in mind lets answer the question:
A. Sucrose C₁₂H₂₂O is an organic compound which we know are made of C. H and O (in this case) atoms with covalent bonds.
B CaCl₂ is an ionic compound, as are C BeF₂ and D BaF₂ from metals (Ca, Be, Ba) and Halogens Cl, F ( nonmetal). Remember when have compounds from groups I and II and VII we have ionic compounds where the metal ion gives up its electrons and the halogens, in this case gain those electrons.
Distill water since it is pure (i.e, does not have ions dissolved) and is a covalent substance is nonconducting.
