Solids and Liquids. Chapter 14. Intermolecular forces . Intramolecular forces. The forces that occur among molecules that cause them to aggregate to form a solid or a liquid. Bonding forces that hold atoms together within a molecule . Intermolecular forces.
The forces that occur among molecules that cause them to aggregate to form a solid or a liquid
Solubility (or Soluble)
Insolubility (or insoluble)
Incapable of being dissolved within a given solution
The amount of substance of solute, divided by the mass of solvent.
The number of moles of solute divided by the number of kilograms of solvent
Moles of solute = mol Kg of Solution kg
* indicate the correct formula and charge of each ion
