Select all of the following choices that would be a nonconducting substance or dissolved in water)a. sucrose c12h22o11b. cacl2c. bef2d. baf2e. distilled water

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.

the answer is definitely c.
