The ability of a material to be drawn out into long, thin strands is called:

When can ionic compounds carry electric current? (check all that apply)

What is the advantage of polymers?

What phenomenon allows bugs to walk on water and accounts for bubbles to be able to expand without popping?

Rank the forces from weakest to strongest.

Statement A: Propane (H₃CCH₂CH₃) has a lower boiling point than pentane (H₃CCH₂CH₂CH₂CH₃).

Statement B: Shorter molecules are less polarizable and have weaker London dispersion forces than long molecules.

Statement C: Statement B explains why Statement A is true.

Statement A: The melting point of iron is higher than the melting point of iron(III) bromide (FeBr₃).

Statement B: Metallic bonds are stronger than covalent bonds.

Statement C: Statement B explains why statement A is true.
