What happened to the atoms in the heated metal ball so
that it didn't fit through the ring?

Many ionic compounds and a few highly polar covalent compounds are because they completely ionize in water to create a solution filled with charged ions that can conduct an electric current.

If the solubility of a gas in water is 1.22g/2.75 atm, what is it’s solubility (in g/l) at 1.0 atm

Which of the following is not a characteristic of a hydrogen bond? 1. it is responsible for the unusual physical properties of water. 2. it is weaker than a covalent bond. 3. it is stronger than other dipole-dipole interactions. 4. it can occur when hydrogen is covalently bound to very electronegative elements liks f, cl, br and i.
